摘　　要：首先,通过平面磨削过程动力学模型,对平面磨削颤振的发生和发展进行分析。然后,设计平面磨削颤振的试验方案,获得磨削颤振和磨削表面波纹度的试验结果,进而研究不同的磨削条件对磨削颤振和磨削表面波纹度的影响,得到与理论分析一致的结果。最后,给出磨削颤振和磨削表面波纹度之间的相互关系,研究表明,在平面磨削过程中,磨削深度是影响磨削颤振和磨削表面波纹度的主导因素;在较大的磨削深度条件下,磨削颤振的幅值和磨削表面的波纹度幅值随着工件速度的增加有显著增大的趋势。First, based on a dynamic model of surface grinding processes, the generation and development of surface grinding chatter are analyzed. Then, the experimental scheme of grinding chatter in surface grinding process is designed. The experimental results of grinding chatter and ground surface waviness on the precise surface grinding machine are obtained. The influences on grinding chatter and ground surface waviness under the diverse grinding conditions are investigated, and it corresponds with theoretical analysis. Finally, the relationship between grinding chatter and ground surface waviness is presented. The results show that cutting depth is the leading factor in grinding chatter and ground surface waviness in surface grinding process, and there is an obvious increasing tendency of chatter amplitude and surface waviness amplitude with the increase of workpiece speed under the condition of large cutting depth.
