摘　　要：以起重量为200t、跨度为31m的桥式起重机为例,运用Visual C++6.0对ANSYS进行二次开发,借助ANSYS自带的参数化设计语言(APDL),根据桥式起重机桥架结构的特点,采用自底向上的方法建立桥架结构的参数化有限元模型,并实现有限元分析过程的程序化。在此基础上,研究影响主梁上盖板开门处应力分布的各个因素,为今后大吨位桥式起重机主梁上盖板开门处的合理设计提供有益的参考。Faking a overhead crane with lifting capacity 200 t and span 31 m for example, the paper apphed Visual C＋＋6.0 to the second development of ANSYS. The paranaetric model of the bridge structure was set up by bottom-up method using ANSYS Parametric Design Language （APDL）, and the procedural process of finite elcment analysis was realized. On this basis, the paper studied the various factors affecting the stress distribution of the main beam cover, provided a useful reference for the rational design of large-tonnage overhead crane cover of the main beam.
