【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。
[Abstract]:Hydrodynamic pressure suspension polishing machine requires a minimal polishing gap to form a polishing liquid film. The small vibration of the polishing machine may have a great impact on machining. Based on the Workbench simulation platform, The effects of different properties of synchronous belt on the vibration characteristics of polishing machine are numerically simulated. The parameters affecting the transverse vibration of synchronous belt are obtained by motion analysis, and the orthogonal test is constructed as a factor, and the simulation is carried out under different factors and levels. By measuring the influence of various factors on the vibration characteristics of the polishing machine, it is found that the material properties have the greatest influence on the vibration characteristics, the bandwidth is the second, and the tension force is the least, and the best combination is obtained according to the actual situation, which effectively improves the stability of the polishing machine. The structure is optimized.
