THE IMPACT OF THE MOTION PATH OF THE STRAW-WALKER KEY ON THE PROCESS OF ROUGH SEPARATING 秸秆行走键运动轨迹对粗分选过程的影响
O. Kosilov, E. Chumachenko
The ways of productivity rise of the straw-walker keys are exhausted. Other dynamic effects on the heap layer in the straw-walker different from rotational movement of keys in modern straw-walkers are studied. The quantitative assessment of the separating efficiency process depending on different motion paths of the keys is also executed. Keyword Straw-walker, key, motion path, separating. Общеизвестно, на сегодняшний день, что возможности клавишного соломотряса, у которого клавиши совершают вращательное движение, исчерпаны и он сдерживает дальнейший рост производительности зерноуборочных комбайнов классической схемы. Различного рода дополнительные устройства в виде ворошителей, активаторов и тому подобного, повышают пропускную способность соломотряса на 10...12%, что в реальных условиях эксплуатации практически не сказывается на производительности комбайна. Таким образом, необходимы иные способы воздействия на ворох, обеспечивающие прорывной рост эффективности сепарации. В середине 20-го века предполагалось, что в процессе движения слоя вороха по клавише зерно из верхних слоев опускается вниз к поверхности клавиши. Зерна, находящиеся в верхних частях слоя, получают незначительные воздействия со стороны клавиши в силу неголономности связи их с соломистыми компонентами слоя вороха, через который эти воздействия зернам передаются [1]. Однако, по мере приближения зерен к поверхности клавиши эти воздействия будут возрастать, что приведет к снижению скорости их опускания и если по достижении поверхности клавиши они не попадут в отверстие решетчатой поверхности клавиши, то они неизбежно будут заброшены клавишей снова в слой вороха, так как движение частиц по поверхности клавиши происходит с отрывом. Так как скважность решетчатых поверхностей клавишей достаточно мала [2], то 30...35% зерна подвергается этой процедуре, что приводит к замедлению процесса
《straw-walker keys的崛起》。在现代斯特拉斯特拉斯工作室里,另一个动态反应者在海法层。在这种情况下,钥匙的决定是不确定的。Keyword Straw-walker, key, motion path, separating。众所周知,到目前为止,键盘吸管的旋转能力已经耗尽,阻碍了经典电路谷物加工机生产率的进一步提高。各种各样的额外设备,如麻雀、激活器之类的,提高了吸管的容量10……12%,在实际操作中,这几乎不会影响联合收割机的性能。因此,需要其他方式来影响漩涡,以确保分离效率的显著提高。在20世纪中期,人们认为,随着一层麻雀的移动,上层的谷物会下降到琴键的表面。由于它们与麻雀层的稻草成分联系不全,在上层的谷物受到了微小的影响。然而,随着零按键表面的这些影响将会增加,导致速度下降陷落如果实现按键表面他们不落入键盘筛孔表面,那么他必然将键盘又一层层的,如废弃键盘表面颗粒运动发生井喷。因为键盘上的晶格表面不够大,所以30……35%的粮食受到这个过程的影响,导致了这个过程的减慢。

ANALYSIS OF EFFECTIVE ELASTIC PROPERTIES FOR MASONRY WITH DIFFERENT VOID SHAPES AND VARIOUS POROSITY 不同孔洞形状和不同孔隙率砌体的有效弹性性能分析
A. Nasedkina
The paper presents the calculation of the effective properties of masonry as a regular composite structure, which consists of the materials of brick and mortar. For the homogenization of masonry, the effective moduli method is used, which considers the representative volume as a periodic cell of masonry structure. For the inhomogeneous medium of the representative volume, several boundary-value problems of the elasticity theory with special boundary conditions are set, which are solved using the finite element method. The computation results are averaged by the representative volume, which allows computing the full set of the effective moduli for the composite structure. The suggested approach is used for the calculation of the effective properties of masonry made of porous and hollow bricks with various void shapes and number of voids, as well as different porosity. The dependence of the effective moduli values on the brick porosity and void sizes is analyzed.
本文介绍了砌体作为一种由砖和砂浆组成的规则复合结构的有效性能计算。对于砌体的均质化,采用有效模量法,将代表体视为砌体结构的周期单元。针对具有代表性体积的非均匀介质,设置了若干具有特殊边界条件的弹性理论边值问题,并采用有限元法进行了求解。计算结果按代表体积求平均值,从而可以计算出复合材料结构的全部有效模量。该方法用于计算不同孔洞形状和孔洞数量以及不同孔隙率的多孔砖和空心砖砌体的有效性能。分析了有效模量值与砖的孔隙度和空隙度的关系。

POWER OF THE STAND DRIVE FOR TESTING SPRING STRAPS ON TARGET STRENGTH 机架驱动器的功率,用于测试弹簧带的目标强度
V. Ignatenko, A. Rulevski, V. Demina
The work is devoted to the search for ways to reduce the energy of the stands for testing the spring racks of the cultivator for fatigue strength. The mechanism of the drive in the form of a crank-rocker mechanism is considered, where a spring stand serves as a yoke. An expression is obtained for determining the maximum instantaneous power under cyclic loading. The dependence on the dynamic characteristics of the elastic link is noted. The spectrum of the natural frequencies of the rack is determined. The dependence of the power of the drive motor on the rotational speed is determined experimentally. It is established that the minimum power per drive is obtained if the frequency of rotation coincides with the natural frequency of the spring column. The conclusion is made about the need for the drive to work in resonance mode with a spring post.
