摘要
以有限元分析软件ANSYS为主要工作平台,建立了液压油缸模型。根据实际工况对其约束与载荷作了有效处理,并对其强度进行了有限元分析,得到油缸缸体位移与应力分布规律。改良前油缸在测试过程中,因油压高致使油缸容易内漏,借助于有限元分析结果,对油缸缸体增加壁厚,缩短缸体长度。改良后的液压油缸在ANSYS分析中,内壁应力减小,在工程测试中,无油缸内漏现象发生。
A hydraulic cylinder mode is established with the finite-element analysis software ANSYS as the main working platform. According to the actual conditions, the constraint and the load of the hydraulic cylinder are dealt with effectively, and the strength is carried out with the finite-element analysis, getting the regular pattern of the cylinder body displacement and stress distributexl. Before the improvement of hydraulic cylinder, the hydraulic cylinder leaked easily in the test process due to the high pressure. With the results of finite-element analysis on the cylinder, the cylinder body increase wall thickness and shorten the length of the cylinder. After improvement of the cylinder, internal stress decreases in ANSYS analysis. And meanwhile, the phenomenon of cylinder leakage doesn＇t happen in engineering testing.
