摘要
介绍了ANSYS软件子模型法的使用方法,说明了设置结构诱导缝的作用,并利用子模型法对小湾拱坝结构诱导缝进行有限元计算,使用APDL参数化语言进行相应的二次开发辅助计算,分析子模型法的适用场合及其优缺点.分析结果表明,用子模型法对结构物进行有限元分析,可以得到结构部分区域更加精确的数值解,大大降低了计算工作量,且有利于提高计算精度.
The submodel method of ANSYS software was introduced. Based on its application to finite element calculation of inducement slot of Xiaowan Arch Dam and the secondary developemt with APDL parameterized language for auxiliary calculation, the function of the inducement slot was explained. Then the scope of application of the submodel method and its advantages and disadvantages were analyzed. The results show that the submodel method, used for finite element analysis of hydraulic structures, can improve the calculation accuracy. This method can greatly reduce the workload of calculation.
