Operability of MAN F2000 Trucks in the North MAN F2000卡车在北方的可操作性
Gennadiy Zudov, I. Buslaeva, A. Levin
Experience in operation of trucks shows a significant increase in a failure number of their systems and parts in natural and climatic conditions of a permafrost zone compared with the conditions of a moderate climate. This article presents a study of operability of the forty MAN F2000 trucks used in Yakutia for long-haul transport. The systems were identified that limit reliability of these vehicles in the severe operation conditions of the North. These are an engine, suspension and brake system. Regularities of changes in the main operability parameters (operating time to failure and operating time between failures) of these systems and truck as a whole were investigated. Regression models of dependences of the operating time between failures on truck mileage for the engine, the suspension and brake system show a significant decrease in this operating time with the increase in the mileage. Taking into account this decrease, an improved technique of calculating the planned repair number for the systems and parts of automobiles, based on statistical information about the failures of these assembly units in the specific operation conditions is proposed. This technique can be used when planning the repairs of the vehicles with the different mileage and calculation of the required number of the spare parts. Keywords—truck; operability; operating time to failure; operating time between failures; mileage; natural and climatic conditions of the North
卡车的运行经验表明,与温和气候条件相比,在永久冻土带的自然和气候条件下,卡车系统和部件的故障数量显著增加。本文介绍了在雅库特用于长途运输的40辆MAN F2000卡车的可操作性研究。这些系统限制了这些车辆在北方恶劣操作条件下的可靠性。这些是发动机、悬架和制动系统。研究了各系统及整车主要可操作参数(故障间隔时间和故障间隔时间)的变化规律。发动机、悬架和制动系统故障间隔时间与行驶里程相关性的回归模型表明,随着行驶里程的增加,故障间隔时间显著降低。考虑到这种减少,提出了一种基于特定运行条件下这些装配单元的故障统计信息计算汽车系统和零件计划修理次数的改进技术。该技术可用于规划不同里程车辆的维修和计算所需备件数量。Keywords-truck;可操作性;故障前运行时间;故障间隔时间;里程;北方的自然和气候条件

The Approach to Automating the Control of the Vibrational Field of a Technological Machine 工业机械振动场的自动化控制方法
S. Kruglov, S. Kovyrshin, R. Bolshakov
The article considers the task of controlling a technological vibration machine, designed for the vibration interaction of a granular working medium with details attached to the working body of a vibration machine. The computational scheme of this kind of machine is a solid body on two springs with adjustable stiffness, which can be attributed to symmetric systems that execute a flat oscillatory motion. The task of the automatic control system is to maintain the vibration field at the required level, in particular, the amplitude of oscillations under conditions of a priori uncertainty of the parameters of the vibration machine. A control system is proposed to be built on the basis of a stabilizing regulator with static adaptation, capable of performing a target function with the object nonlinearity, external perturbations and having a simple structure. The features and conditions of functioning of this regulator are considered. A demo example is given.

Using Automated Fare Collection System Data to Determine Transport Demand 利用自动收费系统数据确定运输需求
A. Fadeev, S. Alhusseini
Transport demand (a set of data about trips and passengers mobility patterns in the network) is a golden key for solving a wide range of issues of transportation and town planning problems. These are development of the road network, development and optimization of public transport routes, etc. To determine the transport demand, the complex four-stage model is traditionally used, in which traditional manual surveys are needed. Indirect methods of obtaining information represent a special perspective based on the collection, integration and analysis of large and mixed type of data which been generated by various sources of human life aspects (Urban computing [10], Big data [11, 12]). One of such methods is the analysis transactions of non-cash fare payment in public transport [9 24]. The results of the passenger trips are obtained by comparing the sequence of payment transactions. As a result of processing transactions of non-cash fare payment, a sample is drawn from the general mobility of citizens transported by public transport. The article considers the following tasks: 1. Estimation of the representativeness of the non-cash fare payment transactions sample to the general set of trips. 2. Calculation of the parameters of transport demand based on the trips set’s sample, which obtained as a result of processing transactions of non-cash fare payment. We proposed calculation of the Origin-Destination (OD) matrices, which takes into account presence of nondecrypted transactions. The obtained results allow us to use automated fare collection system (AFC) data to study transport demand: to obtain information about passenger's trip between the stopping points of network route or between transport districts, as well as passenger correspondence, which consist of one or several trips (when traveling with transfers). Keywords— transport demand, passenger flows, passenger trip, Origin-Destination matrices.
交通需求(一组关于出行和乘客出行模式的数据)是解决交通和城市规划问题的金钥匙。这些是道路网络的发展,公共交通路线的发展和优化等。为了确定运输需求,传统上使用复杂的四阶段模型,其中需要传统的人工调查。间接获取信息的方法代表了一种特殊的视角,它基于对人类生活各方面来源产生的大量混合类型数据的收集、整合和分析(城市计算[10],大数据[11,12])。其中一种方法是分析公共交通非现金票价支付交易[9 24]。乘客旅行的结果是通过比较支付交易的顺序得到的。作为处理非现金票价支付交易的结果,从乘坐公共交通工具的公民的一般流动性中抽取样本。本文主要考虑以下几个任务:1。估计非现金票价支付交易样本对一般行程集的代表性。2. 根据处理非现金票价支付交易得到的出行集样本,计算交通需求参数。我们提出计算原点-目的地(OD)矩阵,其中考虑了未解密事务的存在。获得的结果允许我们使用自动收费系统(AFC)数据来研究交通需求:获得乘客在网络路线停靠点之间或在运输区域之间的行程信息,以及乘客通信,包括一次或多次行程(当换乘时)。关键词:交通需求,客流,旅客出行,出发地-目的地矩阵。

Safety of Railway Transport Facilities Operating in Extreme Climatic Conditions 铁路运输设施在极端气候条件下的运行安全
G. Struchkova, T. Kapitonova, A. Levin
Railway facilities in the Northern territories of Russia are built and operated in the areas of the cryolithozone and low climatic temperatures. Railway transport in the Republic has been operating since 1979. In 2004, a 360 km long highway to Tommot was built. Passenger and cargo transportation to Tommot station has been carried out since 2006. In 2014, the Tommot Nizhny Bestyakh section was built with a length of more than 400 km. Currently, intensive preparation of the construction of the Berkakit-YakutskMagadan railway is underway in Yakutia. However, railway transport is one of the potential sources of emergency situations with a large number of victims, significant material damage and adverse environmental consequences. Accidents and emergencies at railway transport facilities are caused by the complex natural and climatic conditions of the region, violation of technical and technological regulations during construction and operation, factory defects of structures and materials, dangerous natural and climatic phenomena, degradation of the cryolithozone and interaction of technological elements and objects with the natural environment, human factor. This article presents an analysis of the main risk factors of railway transport facilities under construction and operating in the extreme conditions of the North. To ensure the the necessary indicators of reliability and durability of components and assemblies of railway equipment operating in cold climates, a regional technical regulation is developed for the operation of railway rolling stock, traction, track facilities and lifting mechanisms. The procedure used for risk analysis is focused on the consideration of emergency situations in which damage and losses may be caused. Key wordsrailway transport; risk factors; accidents and failures; difficult climatic conditions; cryolitozone
俄罗斯北部地区的铁路设施是在冰冻岩石带和低气候温度地区建造和运营的。共和国的铁路运输自1979年以来一直在运作。2004年,开通了通往托莫特的360公里长的高速公路。从2006年开始,将乘客和货物运送到托莫特站。2014年,修建了长度超过400公里的托莫特-下拜斯泰akh路段。目前,雅库特正在加紧筹备建设贝尔卡吉特-雅库茨克-马加丹铁路。然而,铁路运输是造成大量受害者、重大物质损失和不利环境后果的紧急情况的潜在来源之一。铁路运输设施的事故和突发事件是由于本地区复杂的自然和气候条件,在建设和运营过程中违反技术和工艺规定,结构和材料的工厂缺陷,危险的自然和气候现象,冰冻岩石带的退化以及技术要素和物体与自然环境、人为因素的相互作用造成的。本文分析了在北方极端条件下铁路运输设施建设和运行的主要风险因素。为了确保在寒冷气候下运行的铁路设备的部件和组件的可靠性和耐久性的必要指标,制定了铁路车辆、牵引、轨道设施和起重机构运行的区域技术规程。用于风险分析的程序侧重于考虑可能造成损害和损失的紧急情况。关键词:铁路运输;风险因素;事故和失败;恶劣的气候条件;cryolitozone

— The article reviews the simulation of functional dependence of the heat treatment process time of vermiculite concentrates on their size groups (fractions) in power process units with a mechanical base plate, in which the movement of expanded vermiculite is set by vibro-transporting bulk material in the thermal field of electric heaters. At present we research the process of conductive layer-by-layer heat transfer into the vermiculite grains with the purpose to figure out the so-called “expected time” of temperatures balancing and the time of full expansion in the process of heat treatment of concentrates. The experimental data on the firing time of vermiculite concentrates from various deposits and their comparison with the results of analytical simulation are presented. It was firstly found that grain size of vermiculite concentrates depends on the duration of firing. This dependence was proved by the experimental results of the research.
本文综述了基于机械底板的动力装置中蛭石热处理工艺时间的功能依赖性模拟,该模拟集中在蛭石的粒径群(分数)上,其中膨胀蛭石的运动由电加热器热场中的振冲输送块状物料来设定。目前我们研究的是蛭石颗粒中导电层层传热的过程,目的是求出精矿热处理过程中所谓的温度平衡“预期时间”和充分膨胀时间。给出了不同产地蛭石精矿烧成时间的实验数据,并与分析模拟结果进行了比较。首先发现蛭石精矿的晶粒大小与烧制时间有关。本研究的实验结果证明了这种相关性。

A new approach to assessing the competence of aviation security screeners was proposed and tested, allowing taking into account the parameters of oculomotor activity and heart rate variability of test aviation security screeners, and differing from the existing approaches by using fuzzy classification models. According to the results of an experimental study, three different models were synthesized. The results of the comparison showed that the Sugeno model, trained using the ANFIS-algorithm, is more accurate than the Mamdani model and the linear regression model depends on the competence assessment of aviation security screeners. It described ways of addressing the important task of obtaining more precise relevant digital data in network training complexes using noise-resistant coding tools. It presented a model of a permutation decoder of a non-binary redundant code based on a lexicographic cognitive map. This model of a redundant code decoder uses cognitive data processing methods for completing permutation decoding procedures in order to protect remote control commands from the influence of destructive factors on the control process.
在本文中,对世界经验进行了分析,并得出结论,提高俄罗斯联邦航空安全效率的方法之一是使用现代网络训练综合体。提出并测试了一种新的航空安检人员能力评估方法,该方法考虑了测试航空安检人员的动眼肌活动和心率变异性参数,并使用模糊分类模型与现有方法进行了区别。根据实验研究结果,综合了三种不同的模型。对比结果表明,使用anfiss算法训练的Sugeno模型比Mamdani模型更准确,线性回归模型依赖于航空安检人员的能力评估。它描述了使用抗噪声编码工具解决在网络训练复合体中获得更精确的相关数字数据的重要任务的方法。提出了一种基于词典学认知图的非二进制冗余码排列解码器模型。该冗余码解码器模型采用认知数据处理方法完成排列解码过程,以保护远程控制命令不受破坏性因素对控制过程的影响。
