摘要
主梁作为桥式起重机的主要承载结构之一,其重量在整机中占有比较大的比重。传统的主梁设计是依据经验进行反复的试凑、校核,从而最终确定设计方案,虽能满足要求,但设计过程复杂、繁琐,设计成本高且往往不是最佳的设计方案。在研究主梁的优化数学模型的基础上,以截面尺寸最小为优化目标,建立优化数学模型并利用Mtlab软件的优化工具箱,通过序列二次规划算法对钢梁截面尺寸进行优化设计,并利用ANSYS对优化后的模型进行有限元分析。从而验证了该结果的可靠性。
Girder as one of the main load-bearing structure of bridge crane, it＇s weight take the major part of the machine＇s total weight. Traditionally, the girder design is according to the experience and then through repeated calculation verification. Then got the final design scheme. Although this result can meet the requiremefftS, b^t this design process is, complex, tedious, high cost and often not the best design solution. Through the research of girder optimization mathematical model with the minimum cross section dimension as the optimization goal. Then using the optimization toolbox of MATLAB, through sequential quadratic programming algorithm to optimize the design of girder size. By using ANSYS finite element analysis of the optimized model to verify the reliability of the results. The application of Sequential Quadratic Programming and the MATLAB optimization toolbox in this paper were briefly introduced.
