摘　　要：港口移动式高架起重机臂架结构设计的好坏将直接影响整机性能的优劣。建立了高架起重机臂架力学模型,通过Matlab/GUI开发了高架起重机臂架结构计算软件,实现了高架起重机臂架强度、刚度和稳定性指标的程序迭代计算。对1200 t·m高架起重机臂架结构进行了优化仿真实验,得到了各幅度下臂架截面参数变化对上述指标的影响,确定了满足指标要求的各截面设计参数。ANSYS分析结果表明,优化后臂架自重较原结构降低了3.7%,为高架起重机臂架结构设计提供了参考。Mobile harbor crane is evolved from mobile crane,and becomes a sort of multipurpose lifting equipment used in harbor, which currently is still in the stage of R＆D in our country. And the quality of boom structure will directly determine the overall performance of crane. To this end, the mechanical model of the boom structure of mobile harbor crane is established, and the calculation software is also developed by using Matlab/GUI for the optimization design of the boom structure. Ultimately, the iterative calculation of strength, stiffness and stability is achieved. Furthermore, a simulation re- search on the optimization of 1200t ~ m mobile harbor crane is implemented, and the impacts of boom cross - sectional pa- rameters on these performance indicators are obtained, thus the best design parameters are determined. ANSYS analysis shows that the boom weight reduced by 3.7% after optimization. The work is useful for the boom structure design of mobile harbor crane.
