基于ANSYS的通用桥式起重机主梁优化设计

Structural Optimization Design of Crane Girder Based on ANSYS

本文以桥式起重机箱形主梁为研究对象,结合现代设计方法中的有限单元法和优化设计方法,建立了主梁结构优化设计的数学模型。结合箱形主梁的结构及承载特点,在有限元分析软件ANSYS中对其进行了结构分析。采用ANSYS中的应用程序开发语言(APDL),编制了主梁的结构优化程序,并完成了主梁的结构优化设计。

This thesis chooses the box girder of the crane as the research object and builds the mathematical model of the gird structural optimization design by combining the finite element method with the optimization design method in modem design method. Combining the structure feature with the loading feature. Using the ANSYS application program development language （APDL）, the structural optimization codes of the girder are programmed and the gird structural optimization design is finished.
