摘 要: 在p元分析的基础上,讨论了解析灵敏度分析的列式和实现方法.以二维几何单元为例推导出隐式微分敏度分析公式,同时给出了利用PCG迭代方法求解灵敏度方程的初始解向量选取方案.计算结果表明本文敏度分析方法是高效的、高精度的. The formula and the implementation of the analytical sensitivity analysis are discussed based on the p element analysis. The implicit differential sensitivity analysis formula is derived for 2D geometric elements, and the strategies are given for selecting a start solution of the PCG iterative method used to solve the sensitivity equations. The computational results show that the method is high efficient and high accuracy.
