针对界面力的大小、作用的位置以及部分给定位移的结构边界始终保持不变的要求,以工程技术人员易懂的方式,导出了基于水平集演化的结构拓扑优化问题的最佳解的必要条件,并构建了相应的法向速度场,研究了由该法向速度场导出的序列解的收敛特性.
Because boundang force, the location of interaction and one part of stuctural boundany of a given displacement should be kept constant. Based on level set movements, necessary conditions for optimizing the solution for structural topology optimization problem were given, respective normal speed field was constructed and convergence characteristics of structural topology optimization solutions derived from normal speed field were obtained.
