摘要
编制了3~5节点轴对称弹塑性有限元程序,对带有法兰的油缸体受壁内均布力作用时缸体截面应力分布规律进行了模拟计算,计算表明,油缸体的开裂失效是由于局部应力集中造成的,并提出了改进措施。
:3~5 nodes axial Symmery elastoplastic model is presented The cross-section stress distri- bution of sylindrical body with rim at one part suffered form distributed load in its inner part is simulated. It is shown that the stress concentrate is the main failure cause, a new way is presented.
