摘要
对非线性静力分析的简化计算方法进行了研究,提出了分段计算法。先计算出在材料屈服极限时的外力载荷值,据此将外部载荷分为两段进行计算。前一段,使用线弹性计算一个载荷步;后一段逐步加载,进行材料非线性计算。以ANSYS WORKBENCH为仿真平台,分别用传统方法和分段法对某汽车手刹进行了计算,结果表明:在保证精度的前提下,分段计算法将计算效率提高了67%。
The simplified calculation methods of nonlinear static analysis are studied, and subsection method is proposed. At first, the external load is calculated when it is at the yield limit of material , the calculation of external load is divided into two stage. First stage, is to use linear elasticity to calculate a load step. Material nonlinear is calculated after a period of progressive loading. By using traditional method and the subsection method, an automobile handbrake is calculated by ANSYS WORKBENCH simulation platform, and the results show that the computation efficiency is improved by 67% through subsection calculation method at the premise of accuracy.
