摘要
运用Pro/E软件建立了液压缸模型,通过ANSYS软件对液压缸各部件在同时承受轴向力和径向力时进行非线性有限元分析,得到了活塞杆、活塞、导向套和缸筒的应力及变形分布云图,在此基础上对液压缸筒进行优化设计,增加液压缸底的圆角半径,重新进行有限元分析,证明了这种方法可以保证液压缸在同时承受轴向和径向载荷时的安全性。
A hydraulic cylinder model is established using Pro/E software. Nonlinear finite-element analysis of hydraulic cylinder various parts, enduring the axial loads and the radial loads were carried on by ANSYS software. By finite element analysis the stress distribution and the deformation of the hydraulic rod, piston, guiding bushing and the cylinder body were given. Based on this, the optimization design to the hydraulic cylinder tube is carries on, and it ensures the safety of the hydraulic cylinder enduring the axial loads and the radial loads, through increases the cylinder bottom to the internal cavity wall transition region radius of curvature.
