具有形状和应力约束的连续体结构拓扑优化及其在框架结构设计中的应用

OPTIMAL TOPOLOGY DESIGN OF CONTINUA WITH STRESS AND SHAPE CONSTRAINTS AND ITS APPLICATION TO FRAME STRUCTURES

  • 摘要: 本文研究了在形状和应力约束下的连续体结构拓扑优化问题,采用满应力法求解保证了应力约束的满足;根据对形状的要求,固定部分单元不被删除,强迫最优拓扑满足设计要求。对框架结构进行了计算,结果表明了算法的正确性。

     

    Abstract: Optimal topology design of continua with stress and shape constraints is studied in this paper. The modified full stress criterion is used to obtain the optimal topology under stress constraints. Some elements are fixed in order to satisfy the shape conditions. The proposed method is applied to frame structure design. Numerical results demonstrate the efficiency and effectiveness of the method.
