目的。分析和概括废物来源,作为构成乌克兰累积废物总量的因素,对环境产生负面影响。根据统计指标的计算结果,构建了乌克兰垃圾堆积的数学模型。研究所选因素之间的相互影响,避免计算中出现非共线性或多重共线性的现象。的方法。运用多元相关回归分析方法进行建模,在对所研究的统计指标进行分析的基础上,筛选出最具统计显著性的因子值,评估它们之间的关系以及这些因子值与所得到的特征之间的关系,为建立数学回归模型提供前提条件。发现。在描述性统计的基础上,对研究的废弃物产生量、利用量、燃烧量、清除量等各因子值进行了分析,并建立了2010-2020年各因子值的变化趋势。统计数据的相关回归分析结果如下:所选因子变量与结果变量之间的相关关系密度;线性确定系数;对回归方程质量的度量。剔除弱相关或多重共线性的因子变量。建立了基于回归-扩散分析的数学模型,并对其充分性进行了检验,计算数据的平均相对误差为6%,最大相对误差为10%。由于引入了非线性变量,对线性数学模型进行了改进,计算数据的平均相对误差为3%,最大相对误差为8%。垃圾产生量、利用量、焚化量和清除量的依赖关系和规律已经确立。已经发展了一个多因素数学模型,建立了不同类型的废物与积累的废物总量之间的关系,废物总量趋于增加,而这反过来又增加了对环境的负面影响。实际的实现。用于预测由于产生、利用、燃烧、清除废物及其组合的综合影响而累积的废物总量的数学装置,这在估计废物积累区域的大小和制定废物处置的远景计划时很重要。

Purpose. The substantiation of the compliance of the selected cement-mineral mixture with the mining and geological conditions of the working location when calculating the parameters of cast or packaged walls, considering the intensity of concrete hardening over time, the compliance of the set strength of concrete with the expected load. Method. To substantiate the compliance of the physical and mechanical properties of the pressure mixture on the means of protection of the production from the side of the fake roof of the coal seam, the values of the limit strength of concrete for uniaxial compression, obtained according to standard tests in laboratory conditions, are used. At the same time, concrete samples are subjected to uniaxial compression, the surfaces of which must be smooth and parallel, which does not correspond to the mine conditions for the construction and operation of cast and packaged protective walls. Quick-hardening liquid mixtures are used in the construction technologies of cast and packaged security walls. For some time, necessary for the hardening of concrete, they are not able to perceive the pressure from the rocks forged by longwall. Therefore, the criterion for evaluating the stability of cast or packaged walls is the correspondence of the rate of growth of the strength limit of the wall to uniaxial compression with the load from the forged roof of the coal seam at the moment of timeτ. Results.The importance of the impact on the strength limit of the concrete wall of each of the factors that create the risk of its destruction has been established. At the same time, the ranges of change of these factors are considered. The largest influence (up to 33%) is exerted by the coal seam capacity factor km. The scientific novelty of the work consists in the integration of the influence coefficients of the factors that create the risk of destruction of the concrete protective wall: its structure; relief of forged and crushed rocks pressing on the wall; chemical aggressiveness of mine water, which is used to dissolve the mixture; the temperature of the mine environment and the power of the coal seam to obtain a formula for calculating the growth of wall strength over time. The practical significance of the work lies in the improvement of the method of calculating the strength of concrete protective walls over time by considering the factors that form the mine conditions of their construction and operation.
目的。在计算浇筑或包装墙参数时,考虑混凝土随时间的硬化强度,混凝土的设定强度与预期荷载的符合度,所选水泥-矿物混合物与工作地点的采矿和地质条件的符合度的证实。方法。为了证实压合料的物理力学性能对煤层假顶板侧面保护装置的一致性,采用了在实验室条件下根据标准试验获得的混凝土单轴抗压极限强度值。同时,混凝土试样受到单轴压缩,其表面必须光滑平行,这与浇筑和包装防护墙的施工和运行不符合矿山条件。快速硬化液体混合物用于铸造和包装安全墙的施工技术。在一段时间内,由于混凝土的硬化所必需,它们无法感知长壁锻造的岩石的压力。因此,评价铸壁或包裹壁稳定性的标准是在时间τ时刻围岩单轴抗压强度极限增长率与煤层锻造顶板荷载的对应关系。结果。影响混凝土墙强度极限的每一个因素对其破坏风险的重要性已经确立。同时考虑了这些因素的变化幅度。煤层容量因子km的影响最大,可达33%。这项工作的科学新颖性在于综合了造成混凝土防护墙破坏风险的因素的影响系数:其结构;对压在墙壁上的锻造和破碎岩石的缓解;矿井水的化学侵蚀性,用于溶解混合物;结合矿井环境温度和煤层动力,得到井壁强度随时间增长的计算公式。本文的实际意义在于,通过考虑构成混凝土防护墙施工和运行条件的因素,改进了混凝土防护墙强度随时间变化的计算方法。

Objective. The aim of the study is to establish the possibility of recognizing the characteristics of the internal state and confirm the influence of atomic or molecular bonds on the change of certain indicators of physical and mechanical properties of non-magnetic metallic (aluminum, copper) and non-metallic (polymeric) materials. Methods. The research is carried out on the basis of magnetic resonance using neodymium magnets and electric current modulated by white noise signal, as well as with the help of two neodymium magnets. Results. When using neodymium magnets and electric current modulated by a white noise signal in the range of 15-20000 Hz to create the effect of magnetic resonance for non-magnetic metallic materials, an increase in strength is observed until peak values are reached with a gradual decrease to the average value. The interaction of magnetic fields of neodymium magnet and electric current occurs in the body of samples at subcrystalline and subatomic levels. Therefore, this effect is explained by the fact that as a result of vibrations in the material there is a compaction of dislocations. At the moment of change of rest friction to sliding friction, the dislocation accumulation barrier is destroyed, after which the process is repeated again. When two neodymium magnets are used to create the effect of magnetic resonance for textolite and Plexiglas, i.e. for a group of non-metallic materials, the theory of a simultaneous decrease in entropy in the form of an increase in orderliness, namely the orderliness of domains and compaction of dislocations, with an increase in strength is confirmed. The influence of magnetic resonance treatment on changes occurring at the atomic and molecular level in polymeric materials is confirmed. Scientific novelty. The established dependences indicate a connection between the strengthening of the material and the improvement of the quality of its structure: ordering of domains and compaction of dislocations created by magnetic resonance. Practical significance. The obtained data give grounds for the development of a complex method of influence on a number of parameters of physical and mechanical properties using magnetic resonance based on neodymium magnets for influence and the possibility of predicting the life cycle.
目标。本研究的目的是建立识别内部状态特征的可能性,并确认原子或分子键对非磁性金属(铝、铜)和非金属(聚合物)材料的某些物理机械性能指标变化的影响。方法。本研究是在利用钕磁铁和白噪声信号调制电流的磁共振基础上,以及借助两块钕磁铁进行的。结果。当使用钕磁铁和由15- 20000hz范围内的白噪声信号调制的电流对非磁性金属材料产生磁共振效应时,可以观察到强度的增加,直到达到峰值,然后逐渐降低到平均值。钕磁体磁场与电流的相互作用发生在样品体内的亚晶和亚原子水平上。因此,这种效应可以用这样一个事实来解释:由于材料中的振动,位错会被压实。在静止摩擦转变为滑动摩擦的瞬间,位错积累屏障被破坏,之后该过程再次重复。当使用两块钕磁铁对textolite和plexglass(即对一组非金属材料)产生磁共振效应时,以有序性增加的形式同时减少熵的理论,即域的有序性和位错的压实性,随着强度的增加得到了证实。磁共振处理对高分子材料在原子和分子水平上发生的变化的影响得到证实。科学的新奇。已建立的依赖关系表明,材料的强化与其结构质量的改善之间存在联系:磁畴的有序和由磁共振产生的位错的压实。现实意义。所获得的数据为开发一种复杂的影响方法提供了依据,该方法利用基于钕磁铁的磁共振来影响物理和机械性能的一些参数,并有可能预测寿命周期。

Purpose: synthesis of a mathematical model of an asynchronous motor, taking into account the impact of changes in the quality of electricity on the processes of heating and heat exchange for an economically justified choice of means of protection. Methodology: Theoretical substantiation of the expediency of using a one-mass thermal model of an asynchronous motor, for the conditions of operation of the latter in conditions of low-quality electricity, in order to determine losses in it. Results: Experimental studies of the operation of an asynchronous motor at nominal load were carried out. The obtained results of the measurements made it possible to determine the parameters of the single-mass thermal model, the heat transfer coefficient of the engine, and the coefficient of its heat capacity.A single-mass thermal model of an induction motor is a mathematical model used to describe the thermal processes occurring in an induction motor. This model is based on the assumption that all motor elements can be combined into one mass that heats up during engine operation. The model assumes that the thermal capacity of the motor is a constant, and the heat flow that is released during the operation of the motor is proportional to the square of the current passing through the motor windings. In addition, the model assumes the presence of thermal conductivity between the mass of the motor and the external environment, which affects the rate of heat dissipation. Scientific novelty: A methodology for determining losses in an asynchronous motor using a synthesized mathematical model is proposed, taking into account the influence of changes in the quality of electricity on the processes of heating and heat exchange in it. Practical significance: The obtained results indicate the adequacy of the proposed thermal model of an asynchronous motor operating in a network with low-quality electricity. Taking into account the fact that for many types of engines in the reference literature,there are no necessary data on the coefficients of heat transfer and heat capacity, and only the thermal time constants for certain types of engines are given, the value of the specified parameters of the model can be obtained on the basis of the methodology presented in the work.A single-mass thermal model can be useful for analyzing the thermal processes occurring in an induction motor and for improving the efficiency of the motor. In particular, it can help determine the optimal operating temperature of the motor, as well as calculate the necessary cooling system to ensure stable operation of the motor under conditions of variable load and temperature conditions.
目的:综合异步电动机的数学模型,考虑到电力质量变化对加热和热交换过程的影响,以经济合理地选择保护手段。方法:从理论上证实使用异步电动机的单质量热模型的便利性,用于后者在低质量电力条件下的运行条件,以确定其损失。结果:对异步电动机在额定负载下的运行进行了实验研究。得到的测量结果可以确定单质量热模型的参数、发动机的传热系数和热容系数。感应电机的单质量热模型是用来描述感应电机中发生的热过程的数学模型。这个模型是基于这样一个假设,即所有的马达元件都可以组合成一个在发动机运转过程中加热的整体。该模型假设电机的热容量为常数,电机运行过程中释放的热流与通过电机绕组的电流的平方成正比。此外,该模型假设电机质量与外部环境之间存在导热系数,这影响了散热速率。科学新颖性:考虑到电力质量变化对异步电动机加热和热交换过程的影响,提出了一种利用综合数学模型确定异步电动机损耗的方法。实际意义:所得结果表明所提出的异步电动机在低质量电力网络中运行的热模型是充分性的。考虑到参考文献中许多类型的发动机没有关于传热系数和热容系数的必要数据,并且只给出了某些类型发动机的热时间常数,因此可以根据本文提出的方法获得模型的指定参数值。单质量热模型可用于分析感应电机中发生的热过程和提高电机的效率。特别是,它可以帮助确定电机的最佳运行温度,并计算必要的冷却系统,以确保电机在变负载和变温度条件下稳定运行。

Purpose. An experimental study on modern cold rolling mills with double feed and turning on the effect of the cold rolling process on the change in the cross-wall variation in a batch of pipes and on the change in the value of the cross-wall variation at the ends of the pipes from the blank pipe to the finished pipe. The methodology is an industrial experiment on modern industrial equipment using modern devices. The study of changes in the cross-sectional variation in a batch of pipes was carried out during pipe rolling on the HPT -40-8 mill with feeding and turning the pipe in both extreme positions of the cage when rolling pipes measuring 25.4x2.11 mm. The study of the change in the cross-wall variation along the ends of the tubes from the blank tubes to the finished tube during rolling with double feed and rotation was carried out on the KPW-25 mill with feed and rotation in both extreme positions of the cage along the route of 33.7x3.2 → 16x1.5 mm steel pipes 08Х18Н10Т. The methods. The study of the change in transverse thickness from the billet to the pipe in a batch of pipes showed that the maximum value of the transverse thickness among the sample of pipes is 5.64%, the minimum is 0.85%. The average value is 3.51%, the root mean square deviation of the values of diversity is 1.174%. It is not always possible to obtain these accuracy values even at the state of the HPT, and when conducting the HPT process, where the feed is performed before the forward stroke, and the pipe is turned before the reverse stroke, it is practically impossible to obtain such indicators. The study of the change in the cross-wall difference along the ends of the pipes from the billet pipes to the finished pipe during pipe rolling on the KPW-25 mill with feed and rotation of the billet in both extreme positions of the cage showed that although the minimum values of the relative difference slightly increased, but in general the wall difference along the ends of the pipes significantly decreased. This makes it possible to reduce the cut at the ends of the pipes and, accordingly, the consumption coefficient of the metal. The originality. Additional experimental dependences were obtained on the change of the cross-wall variation from the billet pipe to the finished pipe in a batch of pipes and the change of the variation along the ends of the pipes during rolling with the execution of feed and rotation before the forward and reverse motion of the cage. Practical implementation. The conducted studies allow us to use the obtained experimental dependencies in the design of routes, deformation modes and determination of roll calibration in the manufacture of pipes with increased requirements for the accuracy of pipes in cold rolling mills, which have the ability to feed and turn the pipe before the forward and reverse movement of the cage.
目的。在现代双进给双转动冷轧机上,研究了冷轧过程对一批管材横壁差变化的影响,以及对管材从毛坯到成品管材两端横壁差值变化的影响。该方法是利用现代设备在现代工业设备上进行的工业实验。研究了在HPT -40-8轧机上轧制25.4 × 2.11 mm管材时,在保持架的两个极端位置进料和转动管材时,一批管材的横截面变化规律。在kpww -25轧机上,对33.7x3.2→16x1.5 mm钢管08Х18Н10Т的路线进行了双进给和双旋转轧制过程中,从坯管到成品管沿两端的横壁变化进行了研究。的方法。对一批管材中从坯料到管材的横向厚度变化进行了研究,结果表明,管材样品的横向厚度最大值为5.64%,最小值为0.85%。其平均值为3.51%,多样性值的均方根偏差为1.174%。即使在HPT状态下,也不可能总是获得这些精度值,并且在进行HPT工艺时,在正向冲程之前进行进给,在反向冲程之前进行管材转动,实际上不可能获得这些指标。在KPW-25轧机上轧制过程中,在保持架两个极端位置加料和转动坯料时,从坯料管道到成品管道沿端壁差的变化研究表明,尽管相对差的最小值略有增加,但总体上沿端壁差明显减小。这样就可以减少管道末端的切割,从而降低金属的消耗系数。的创意。在保持架向前和反向运动之前,在轧制过程中,随着进料和旋转的执行,从坯料管到成品管的横壁变化以及沿管端变化得到了额外的实验依赖关系。实际的实现。所进行的研究使我们能够将获得的实验依赖关系用于路线设计,变形模式和轧辊校准的确定,以制造对冷轧机中管道精度要求更高的管道,冷轧机能够在保持架向前和反向运动之前馈送和转动管道。

Purpose. Analytical justification of the method of strengthening the stability of the water-saturated alluvial soil massif around the subway tunnel by the method of jet cementation using low-viscosity polyurethane. Consider the advantages of this material and present the strength characteristics. The methods. Analytical justification of the method of strengthening the stability of the water-saturated alluvial soil massif around the subway tunnel by the method of jet cementation using low-viscosity polyurethane. Consider the advantages of this material and present the strength characteristics. Findings. The use of a mixture of concrete and low-viscosity polyurethane during jet cementing allows to increase the strength characteristics of piles, thanks to the advantages of polyurethane. The material has a high density, ozone resistance, stability at high and low temperatures, the possibility of use under significant mechanical loads, with a high density, it does not have a large mass, it is elastic. When filling wells with a mixture of cement and polyurethane solution in interaction with water-saturated soil, the physical and mechanical characteristics of the soil and the load on the structure of the metro tunnel change. Based on the analysis of the data on the consolidation of the soil massif, it can be highlighted that to increase the stability of the water-saturated soil massif, it is advisable to use the jet cementation method with the addition of low-viscosity polyurethane. The originality. The use of low-viscosity polyurethane as a cementing material by jet cementation is highly effective in cementing weak water-saturated soils. The use of polyurethane will make it possible to shorten the period of work, reduce the amount of material, and increase operational characteristics. Practical implementation. The silicification method is common and convenient for strengthening underground soil in the case of dense urban development, but the use of piles as a result of mixing soil with polyurethane will not only reduce the duration of work, but also reduce the cost and increase the speed of pile hardening, increase the range of coverage of the water-saturated massif near the tunnel, will reduce the possibility of the formation of an anti-filtration cushion, which is safer for urban development

Analytical justification of the method of strengthening the stability of the water-saturated alluvial soil massif around the subway tunnel by the method of jet cementation using low-viscosity polyurethane. Consider the advantages of this material and present the strength characteristics. Findings. The use of a mixture of concrete and low-viscosity polyurethane during jet cementing allows to increase the strength characteristics of piles, thanks to the advantages of polyurethane. The material has a high density, ozone resistance, stability at high and low temperatures, the possibility of use under significant mechanical loads, with a high density, it does not have a large mass, it is elastic. When filling wells with a mixture of cement and polyurethane solution in interaction with water-saturated soil, the physical and mechanical characteristics of the soil and the load on the structure of the metro tunnel change. Based on the analysis of the data on the consolidation of the soil massif, it can be highlighted that to increase the stability of the water-saturated soil massif, it is advisable to use the jet cementation method with the addition of low-viscosity polyurethane. The originality. The use of low-viscosity polyurethane as a cementing material by jet cementation is highly effective in cementing weak water-saturated soils. The use of polyurethane will make it possible to shorten the period of work, reduce the amount of material, and increase operational characteristics. Practical implementation.
