摘要
以MSC.Patran为二次开发平台,以Marc为求解器,充分利用PCL语言批处理命令的功能,通过制定自定义菜单和图形界面,开发了铝合金厚板残余应力分析软件系统,实现了预拉伸消减残余应力过程的前处理(几何建模-网格划分-边界条件施加及淬火残余应力到预拉伸初始条件的映射-材料属性定义)-分析-后处理等一系列工序的自动化和参数化.结果表明:该系统计算结果准确,误差率最大仅为8.5%,使用方便,大大提高了分析效率.
Pre-treatment (geometric modeling-grid-boundary conditions-material attribute definition ) -analysis- post-processing are needed when the different plate sizes, solid solution, quenching temperature, thermal con- ductivity, stretching rate and other parameters are taken into consideration on the residual stress analysis. The mathematical model is set up for each set of parameters for analysis, repeating operation, the analysis efficien- cy is low. Based on MSC. Patran for secondary development platform, were based on Marc solver, make full use of the powerful features of the Patran command language, by making the custom menus and graphical in- terface, can submit automatically parameterized modeling, analysis, and read the result of analysis. The alu- minum alloy thick plate residual stress analysis software system is developed. The results show that the system calculation results are accurate, convenient and practical, and the efficiency is improved greatly. The error limit is 8.5%.
