摘　　要：采用ANSYS软件的二次开发语言,建立了门式起重机的有限元模型,对其模型进行静态和动态分析,得到起重机的变形、应力强度和模态固有频率。以起重机整体结构为研究对象,以起重机整体质量最小和起重机的模态固有频率在满足条件的情况下最大为优化目标,对起重机的结构参数进行优化设计。优化结果表明,在满足约束条件的情况下,起重机的整体质量可以降低21.6%,模态固有频率也能够满足起重机要求,降低了起重机的制造成本,改善了起重机工作性能。Using ANSYS secondary development language, the finite element model of gantry crane is built. Through the study of the static and dynamic analysis of the model, the crane deformation, stress intensity and model frequencies are got. Making crane structure as the object of study, making the overall quality and crane model frequencies in under the condition of maxi-mum satisfying conditions as object of optimization, then the structural parameters is optimized. Optimized results shows that in the case of satisfying the constraint conditions, the overall quality of the crane can be reduced by 17. 8% , reduces the man-ufacturing cost of the crane is reduced and the working performance of the crane is improved.
