以图形参数为设计变量 ,以机架牌坊内最大应力最小为追求目标 ,运用边界单元法与罚函数法耦合求解牌坊窗口上下转角处的形状参数 ,得出了较理想的结果。
Taking the graphic parameters as the design variables, the maximum stress in the frame of the frame is the pursuit of the goal, the boundary element method and the penalty function method are used to solve the shape parameters of the upper and lower corners of the arch window, and the ideal result is obtained.
