摘要磨削颤振是制约凸轮轴高效优质磨削最主要的因素之一。在分析凸轮轴磨削几何运动学特性的基础上，综合考虑时滞效应和砂轮-工件弹性退让机制推导了凸轮轴高速磨削动态磨削力计算方法，建立了多因素耦合的凸轮轴磨削动力学模型和凸轮轴动态磨削仿真模型。基于稳定性叶瓣图法和动态磨削过程仿真方法对凸轮轴高速磨削稳定性进行预测分析；开展实验验证了所提出模型和方法的正确性。最后，通过对动态磨削过程的变模态参数仿真，分析模态参数对凸轮轴高速磨削过程稳定性的影响。结果表明：增大系统刚度和阻尼、减小模态质量都可以改善磨削稳定性，获得更大的稳定磨削极限。

Abstract：Grinding chatter is one of the most important factors for restricting the efficient and high-quality grinding of camshaft. Based on the analysis of the geometric and kinematic characteristics of camshaft grinding, the calculation method of dynamic grinding force in high-speed grinding of camshaft is deduced considering the time delay effect and the elastic concession mechanism of grinding wheel-workpiece comprehensively, and the multi-factor coupling camshaft grinding dynamics model and camshaft dynamic grinding simulation model are established. Based on the stability lobe diagram method and dynamic grinding process simulation method, the high-speed grinding stability of camshaft is predicted and analyzed. Experiments are carried out to verify the correctness of the proposed model and method. Finally, the influence of modal parameters on the stability of camshaft high-speed grinding process is analyzed by simulating the variable modal parameters of dynamic grinding process. The results show that increasing the stiffness and damping of the process system and reducing the modal mass of the process system can improve the grinding stability and obtain a greater stable grinding limit.
