摘　　要：本文以起重量为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,着力研究影响主梁腹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腹板开门处的合理设计提供有益的参考。Taking the weight of 200t, span 31m overhead crane as an example, the use of Visual C＋＋6.0 on the ANSYS second development that comes with the ANSYS Parametric Design Language （APDL） under the crane bridge structure is characterized by the use of bottom-up method to establish the parameters of the bridge structure finite element model, and finite element analysis to achieve the procedural process. On this basis, taking efforts to study the various factors that affect the main beam web door at the stress distribution, and provide a useful reference for the rational design of future large tonnage bridge crane cover to open the door at the main beam.
