摘要： 为了解决双盘直槽研磨方法实施过程中的关键技术问题，针对圆柱滚子在研磨状态下的自转运动展开相关研究。首先，对圆柱滚子在研磨状态下的自转运动进行理论分析，得到了其稳定自转的条件。然后，基于ADAMS （automatic dynamic analysis of mechanical systems，机械系统动力学自动分析）软件建立了圆柱滚子自转运动的动力学仿真模型，并以圆柱滚子与上、下研磨盘间的摩擦系数，下研磨盘V形槽半角，单个圆柱滚子所受研磨载荷及上、下研磨盘相对运动线速度为主要影响因素，以圆柱滚子的相对滑动率为评价指标，进行了计及因素间交互作用的正交试验。通过响应均值分析与方差分析，得到了可实现圆柱滚子稳定且连续自转的最优参数组合。最后，在自主设计的圆柱滚子自转运动试验平台上对最优参数组合的正确性进行了验证试验。试验结果表明，最优参数组合下圆柱滚子自转时的平均相对滑动率仅为0.30%，能够实现稳定且连续的自转，这充分证明了通过理论分析与正交试验得到的最优参数组合的正确性。研究结果证实了基于双盘直槽研磨的圆柱滚子自转运动的合理可行域，其对双盘直槽研磨方法的工程实践具有指导意义，为提高圆柱滚子批直径尺寸一致性奠定了基础。
Abstract: In order to solve key technical problems in the implementation of double-disc straight groove grinding method, relevant studies on the rotating motion of cylindrical rollers under the grinding state were conducted. Firstly, the theoretical analysis of the rotating motion of cylindrical roller under the grinding state was carried out to conclude the its stable rotation conditions. Secondly, based on ADAMS (automatic dynamic analysis of mechanical systems) software, a dynamics simulation model of the rotating motion of cylindrical roller was established. Taking the friction coefficient between the cylindrical roller and the upper and lower grinding discs, the half-angle of lower grinding disc V-type groove, the grinding pressure on single cylindrical roller and the relative linear velocity of the upper and lower grinding discs as main influencing factors, and the relative sliding rate of cylindrical roller as the evaluation index, an orthogonal experiment considering the interaction between factors was carried out. Furthermore, through the response mean analysis and variance analysis, the optimal parameter combination which could realize the stable and continuous rotation of cylindrical rollers was obtained. Finally, the correctness of the optimal parameter combination was verified on a self-designed experimental platform of cylindrical roller rotating motion test platform. The experimental results showed that the average relative sliding rate of cylindrical rollers during rotation under the optimal parameter combination was only 0.3%, and the stable and continuous rotation could be achieved, which verified the correctness of optimal parameter combination obtained by the theoretical analysis and orthogonal experiment. The research results confirm the reasonable and feasible range of the cylindrical roller rotating motion based on the double-disc straight groove grinding, which has guiding significance for the engineering practice of the double-disc straight groove grinding method, and lays the foundation for improving the consistency of the batch diameter size of cylindrical rollers.
