桥式起重机桥架箱形主梁的传统设计一般采用偏于保守的简化计算方法，并且选用比较大的安全系数，所设计出的箱形主梁往往在一定程度上存在结构笨重、部分材料浪费和造价过高等问题，导致整机的性价比降低。本文应用 ANSYS 软件的优化设计模块，对起重机桥架的箱形主梁结构进行了优化设计分析。应用 ANSYS 软件的 APDL 语言，建立箱形主梁的参数化有限元模型，选取其截面尺寸作为设计变量，对其截面参数进行寻优，在满足其强度和刚度要求的前提下，使其质量减小，性价比提高。

The traditional design of main girder of bridge cranes generally uses conservative and simplified method to de-sign and uses a large safety factor.The main girder design exists a certain extent problems such like bulky structure,mate-rial waste and high costs,which leads to the reduces of the whole cost-effective.This paper used ANSYS software optimized design modules to conduct a optimal design for the main girder of crane bridge structure.By using the internal command and ANSYS APDL language,established the parameterized finite element model of the main beam.The sectional dimensions of the main beam were selected as the design variables to optimize the main beam cross-section parameters.Under the premise of meeting the strength and stiffness of the main girder,minimized total weight and improved cost performance.
