摘要 针对磨削过程中砂轮的振动失效现象,使用有限元分析软件ANSYS APDL对组合式砂轮的碳纤维砂轮基体进行静止状态下的固有模态分析和旋转状态下有预应力的模态分析。通过对比分析可知,由离心力产生的预应力对砂轮基体固有模态产生的影响很小。采用组合式砂轮结构设计时,能够避免外界激振频率与固有频率接近而引起的共振破坏。模态分析的结果能为砂轮结构的改进设计及进一步动态特性分析提供数据参考。

Abstract: For the vibration failure of the grinding wheel during grinding, the carbon fiber grinding wheel base of the combined grinding wheel is analyzed by using the finite element analysis software ANSYS APDL for the inherent modal analysis in the stationary state and the pre-stressed modal analysis in the rotating state. From the comparative analysis, it can be seen that the prestress produced by centrifugal force has little effect on the inherent mode of the grinding wheel base. In the design of the combined grinding wheel structure, it is possible to avoid the resonance damage caused by the closeness of the external vibration frequency to the natural frequency. The results of modal analysis can provide data refe-rence for the improved design of the grinding wheel structure and the analysis of further dynamic characteristics.
