AGC伺服液压缸结构优化

Structure Optimization of AGC Servo Hydraulic Cylinder

针对我国某一钢厂的轧机AGC伺服液压缸出现的故障进行了分析,对出现伺服液压缸缸体底部裂损进行了详细的研究。首先使用Solidworks对缸体进行建模,并对缸体外径和底部厚底进行参数化设置,用ANSYS对其进行了有限元三维优化分析,选择出较佳的参数模型,再次对底部倒圆角和倒斜角进行参数化设置,且用ANSYS有限元分析,比较两者优化的结果,选择较佳的优化方案。最终优化方案相比原始优化方案,不仅节约材料成本,而且结构应力也明显减小,满足工作需求。

This paper analyses the failure of the rolling mill＇s AGC servo hydraulic cylinder in a certain factory, especially the cracked bottom of the cylinder. Firstly, model the cylinder and set the parameters for the external diameter and thickness of the cylinder with Solidworks. Secondly, make the three-dimensional finite element optimization analysis with the help of ANSYS. Then select the optimal parametric model and set parameters for bottom comer and beveling again. Fourthly, make the finite element analysis by ANSYS and compare the two schemes of the optimal result, then choose the better one. Compared with the original one, the final scheme is cost-saving and also meet the working demand because of the obviously smaller structure stress.
