摘要
本文以某规格进口双缸双作用隔膜泵液力端活塞杆为研究对象,利用有限元分析专用软件ANSYS对其产生裂纹的成因进行分析并提出不同的几种结构改进方案,最终确定了应力分布最优、应力集中程度最小的结构形式,为同类产品的设计和研发提供了设计依据,具有一定的实践指导意义。
In this paper,the hydraulic piston rod of an imported double-cylinder double-acting diaphragm pump is taken as the research object,and the causes of cracks are analyzed by finite element analysis software ANSYS,and several structural improvement schemes are put forward.Finally,the structural form with the best stress distribution and the least stress concentration is determined,which provides a design basis for the design and research of similar products and has certain practical guiding significance.
