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.
Abstract:
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. Themathematical 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 fulluse 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 systemcalculation results are accurate,convenient and practical,and the efficiency is improved greatly. The errorlimit is 8.5 %.
