摘要
桥式起重机的性能很大程度上取决于箱形梁结构。笔者通过详细论述基于ANSYS的拓扑优化实现过程,以30t起重机主梁为具体算例进行拓扑优化,并根据优化结果建立空腹式箱形主梁模型。分析结果显示,采用空腹式箱形梁在满足设计要求的前提下减轻了主梁的自重,为箱形梁的结构设计提供了一定的参考。
The performance of bridge crane largely depends on its box girder structure.The paper elaborates the implementation procedure of topology optimization based on ANSYS.Taking the model of 30t crane girder to conduct topology optimization,and according to the optimization results,the hollow model of box girder is built and analysed.The results show that the hollow box girder not only satisfies the designing requirements,but has less deadweight,which offers references for structural design of box girder.
