Research on the process parameters of bionic surface texture applied to double elastic spindle
摘要
Abstract
To process bionic shell-like surface texture on double elastic spindles and achieve mass production,based on random vibration module in finite element software Ansys,a simulation model of bionic shell-like surface texture double elastic spindles with different process parameters was established.The laws of process parameters such as line spacing,column spacing,size,arrangement mode and their combination on the amplitude at the critical speed and maximum stress of double elastic spindles were analyzed,and experiments were carried out to verify.The simulation results showed that under the condition of column spacing change,the texture with the size of 0.5 mm or 0.6 mm,line spacing of 1.3 mm and column spacing of 1.4 mm,vibration could be significantly suppressed,the amplitude at the critical speed could be controlled lower 0.05 mm,meeting the normal operation requirements and the maximum stress was not increased significantly.Under the condition of line spacing change,the texture with the size of 0.4 mm,line spacing of 1.2 mm and column spacing of 1.3 mm also showed better vibration reduction effect,which could expand the stable working speed of the spindle.The texture area occupancy rate and arrangement mode had a significant effect on the performance,when arranged in parallel with the line spacing of 1.3 mm and column spacing of 1.4 mm,the size of 0.6 mm performed the best under a fully-uniform distribution,while the size of 0.9 mm performed the best under a non-fully-uniform distribution,both of them were better than the non-textured state.The staggered arrangement showed better vibration reduction and stress distribution characteristics when the size was 0.8 mm.The coupling effect between parameters was obvious,the coordinated increase of texture size and spacing would strengthen and then weaken dynamic pressure effect,and there was an obvious optimal interval.Neither too high nor too low area occupancy rate was beneficial to the improvement of performance.The reliability of the simulation law was verified by the experiment.The research provides theoretical basis and parameter guidance for the engineering application and mass production of the surface texture applied to double elastic spindles.关键词
