摘要
将有限单元和可变容差法相结合，将几何参数的反分析归结为一个带约束条件的非线性优化问题。应用此模型也可反分析材料力学参数和边界荷载。两个算例表明了模型的良好性能。
In this paper,The geometrical parameter backanalysis is formulated as a nonlinear optimum problem with constraint condition by combining the FEM with the flexible tolerance method.This backanalysis model can be also applied to the identification of boundary loads and material mechanics parameters.Two case studies show a good and stable results.
