摘　　要：针对所设计的一种无泄漏柱塞缸的筒型密封件进行研究,应用超弹性理论和非线性理论,对密封件层叠型结构进行有限元模拟,分析层叠型结构在加载过程中的应力集中现象。设计样机实验,观察层叠型结构在加载过程中的变形,并与模拟结果进行对比。结果表明:层叠型密封件工作时的应力集中在层叠弯折处,层叠型结构在层叠部分产生的大变形与模拟结果一致。基于模拟结果以层叠角度和层叠距离为优化变量对层叠结构进行优化,以提高较大行程下柱塞缸的性能,并对优化后的柱塞缸进行快进工况的有限元模拟,验证优化设计的合理性。Aiming at the cylindrical seal of a leak-free plunger cylinder designed.The super-elastic theory and nonlinear theory are used to simulate the laminated structure of the seal and analyze the stress concentration of the laminated structure during loading.A prototype experiment was designed to observe the deformation of the laminated structure during the loading process and compare it with the simulation results.The results show that the stress of the laminated seal is concentrated at the bending of the laminated structure,and the large deformation of the laminated structure in the laminated part is consistent with the simulation results.Based on the simulation results,the stacking structure is optimized with the stacking angle and stacking distance as the optimization variables to improve the performance of the plunger cylinder under large stroke.The finite element simulation of the optimized plunger cylinder is carried out to verify the rationality of the optimization design.
