摘　　要：运用有限元工具建立某型起重机用三级齿轮减速箱动力学模型,在考虑传动误差和轴系变形的条件下对整机进行动力学特性分析,并提出结构优化设计方案。This paper proposed a method for analyzing the static strength and dynamic behaviors of a three-stage gearing with given parameters by using FEM and the parametric optimization design of the gearing. The 3D FE model of the whole gearing is developed using unique 20 node brick dements. The dynamics model is established based on considering transmission error excitation and shaft compliance as main vibration-exciting facts. Finally, a structural parameter optimization method is proposed to minimize the total weight and noise level of the gearing by optimizing main parameters of the gearing such as modules, tooth numbers and spiral angles.
