摘　　要：利用Pro/E和ANSYS软件建立MKZ84125数控轧辊磨床的有限元分析模型,进行整机的动态分析。研究结果表明:砂轮架是整机结构中薄弱环节。进一步以筋板厚度为设计参数,以砂轮架的固有频率作为衡量结构动态特性优劣的指标,进行筋板厚度对结构固有频率的灵敏度分析。数值仿真结果显示经动态设计后的轧辊磨床比原机床具有更好的动态特性。The FE model of the roller grinding machine MKZ84125 is established using the software Pro/E and ANSYS, the dynamic analysis was studied, which show that the grinding carriage is the frail part that im pacts the dynamics of the whole machine. Thereby the sensitivity analysis between performance of the grinding carriage and design parameters was held. Simulation results show that the dynamic behavior of the whole machine redesigned is better than that of the original machine.
