摘　　要：针对某型号岸边集装箱桥式起重机门框斜撑进行优化设计。首先应用结构拓扑优化技术,建立斜撑拓扑优化设计的模型;通过拓扑优化设计,得到三种斜撑的布置方案。然后基于斜撑的抗风振要求对斜撑进行尺寸优化,得到满足设计条件的质量最轻的优化结果。通过对优化后的斜撑结构在岸桥整机上的刚度和强度校核,验证了提出方法的有效性。Structural design optimization is implemented for bracing bars of the frame of a container crane.The topology design model is constructed based on the structural topology optimization technique,and three layout patterns are obtained on the identification of the results of topology optimization.The sizing optimization of the bracing bars of the frame is then carried out by the consideration of the critical resonance caused by wind,and the lightest structure is gaimed.Finally,the stiffness and strength of crane are checked to validate the effectiveness of the proposed method.
