摘　　要：针对偏心轴在磨削过程中存在冲击和振动而影响加工表面精度和质量的问题,文章分析了偏心轴磨削系统产生的几种振动,通过CATIA三维软件建立了磨削简化模型,同时通过接口互换导入ADAMS进行运动仿真,分析研究了偏心轴磨削过程中换向冲击产生的自由振动导致的加速度曲线变化、砂轮架质量、砂轮架水平进给速度等因素对振动的影响,又分析了工件偏心、砂轮偏心引起的振动,可以为进一步提高表面质量和磨削稳定性的研究提供理论支撑。Aiming at the problem that the eccentric shaft has impact and vibration during the grinding process and affects the accuracy and quality of the machined surface,several vibrations generated by the eccentric shaft grinding system are analyzed.The simplified model of grinding is established by CATIA software.The ADAMS was imported and exchanged for motion simulation.The influence of the acceleration curve caused by the free vibration generated by the commutation shock during the eccentric shaft grinding,the quality of the wheel frame and the horizontal feed rate of the wheel frame on the vibration were analyzed.The eccentricity of the workpiece and the vibration caused by the eccentricity of the grinding wheel is analyzed,which can provide theoretical support for further research on surface quality and grinding stability.
