Dynamic Performance Optimization Design and Research of Ping Qiao of the Abnormal High Tower Crane Based on the FEM

异形高耸塔机的平桥动态性能对其整机性能有重要影响。采用有限元法动态分析理论,建立异形高耸塔式起重机平桥有限元参数化模型,对其进行动态分析。以分析结果作为优化设计的目标函数,采用ANSYS的优化算法模块,对平桥结构进行动态优化设计,通过实验对优化结果进行了可靠性验证,结果表明其有效减轻了异形高耸塔式起重机平桥的质量,提高了平桥金属结构的动态性能,为整机优化奠定了基础。

The dynamic performance of Ping Qiao of abnormal high tower crane is particularly important to the whole structure. Using the finite element method to set up the finite element parametric model of Ping Qiao of the abnormal high tower crane,and then making dynamic analysis. Taking the analysis result as the objective function of the optimization design model,and using the optimization algorithm module of ANSYS to make dynamic optimization design of Ping Qiao structure,the quality of Ping Qiao of the abnormal high tower crane is effectively reduced,the dynamic performance of the metal structure is improved,this lays the foundation for the whole optimization.
