介绍了连续体结构拓扑优化中的棋盘格式问题 ,以及目前解决这一问题常用的几种方法。在此基础上提出了采用高斯窗函数解决棋盘格式问题的新方法 ,并从理论上证明了这一方法的可行性 ,数值计算结果较理想 The problem of checkerboard format in topological optimization of continuum structure is introduced, and several methods commonly used to solve this problem are introduced. On this basis, a new method to solve the chessboard format problem by using Gaussian window function is put forward, and the feasibility of this method is proved theoretically. The numerical results are satisfactory
