摘　　要：因液压缸活塞杆退刀槽处存在应力集中,在往复工作中受冲击力易导致活塞杆断裂失效。使用Solidedges软件对滑移装载机液压缸活塞杆进行建模,使用ABAQUS有限元分析软件分别对曾用结构、目前结构和改进结构活塞杆进行有限元分析,求解出每种活塞杆所对应的应力大小。根据分析结果对活塞杆结构进行优化,提高了活塞杆寿命,保证了滑移装载机的可靠性。To cope with the piston rod fracture failure caused by impact force in reciprocating work due to the stress concentration occuring in undercut position of hydraulic cylinder piston rods,Solidedges software is applied to model the hydraulic cylinder piston rod of the slip loader,and finite element analysis is conducted on the former structure,the current structure and the improved structure of piston rod by ABAQUS software to solve the corresponding stress size of each piston rod.According to the analysis results,the structure of the piston rod is optimized,which improves the service life of the piston rod and ensures the reliability of the slip loader.
