利用Pro／E对单体液压支柱液压缸进行有限元分析和寿命优化。以液压缸疲劳寿命最大和使用材料最少为目标函数，并对缸体强度、许用应力、许用壁厚、稳定性进行约束。利用LINGO软件进行优化求解，得到优化后尺寸。结果表明，缸体能承受的最大载荷值、剩余寿命均有所增加而破损量减小，达到了优化的目的。

It proposes the application of pro/E in the finite element analysis and life optimization of hydraulic cyl-inder of hydraulic prop.It builds the objective function as the maximum fatigue life and minimum materials, de-fines the constraint such as the cylinder strength, allowable stress, wall thickness and the stability.It obtains the optimization model with LINGO, and the optimized size.The results show that optimized cylinder can withstand higher loads.
