摘　　要：通过港珠澳大桥钢箱梁吊具受限吊装工程实例,基于Ansys的应力强度、刚度位移及面外失稳的结构设计计算分析,得到薄弱危险区域和应力分布规律等相关力学性能信息,为优化拓扑吊具结构尺寸和形状以及提高稳定性起到了关键作用。Taking the limited hoisting of the sling for steel box beam of Hong Kong-Zhuhai-Macao Bridge as an example,the paper performs the structural design calculation analysis for Ansys-based stress strength,rigidity displacement,and out-plane buckling,to get data related to the mechanical properties such as hazardous areas and the stress distribution rule,helping optimize the dimension and shape of the topology sling and improve stability.
