矿用液压元件是流体机械进行往复运动中的关键部件,基于有限元法,利用有限元分析软件Solidworks Simulation对某液压元件进行静应力分析,得到液压元件的应力及位移変化云图。提出一种结构改进措施,并且对改进后的结构进行有限元分析,结果表明:结构改进后的液压元件比改进前应力集中减少,应力及位移变化幅度小,该结果为液压元件结构改进提供一定参考价值。 Mining hydraulic components are the key components in the reciprocating motion of fluid machinery. Based on the finite element method, the static stress of a hydraulic component is analyzed by finite element analysis software Solidworks Simulation to get the stress and displacement of the hydraulic components. A structural improvement measure is proposed and the finite element analysis of the improved structure is carried out. The results show that the hydraulic components with improved structure have less stress concentration and less change of stress and displacement than those before the improvement, Reference value.
