摘要
液动压悬浮抛光机要求抛光间隙极小以形成抛光液液膜,抛光机微小的振动都可能会对加工造成极大影响。基于Workbench仿真平台,数值模拟了同步带的不同属性对抛光机振动特性的影响。运动分析得出影响同步带横向振动的参数;以此为因素构建正交试验,并进行不同因素及水平下的仿真;衡量各因素对抛光机振动特性的影响,发现材料属性对振动特性影响最大,带宽次之,张紧力最小,并结合实际情况得出最佳组合,有效提高了抛光机的稳定性,实现了结构的优化。
To form slurry film, hydrodynamic-suspension polishing machine needs polishing clearance extremely small, so any slight vibration will make tremendous influence on machining. The effect of different properties of synchronous belt on vibration characteristics of polishing machine was simulated by Workbench. Motion analysis shows the parameters which influence on transverse vibration of synchronous belt. Orthogonal test was designed and simulation was made by using above parameters. The results released that the material played an important role than the belt width and tension force. According to actual situation, optimum combination was obtained. Consequently, the stability of the machine was obviously improved. The structure optimization was realized.
