摘要
本文介绍了C6132车床结构实验模态分析的测试、分析与结果。通过对该车床结构随机激励的响应测试分析,识别其模态参数和模态振型,从而找出有害模态。同时也分析了不同转速下车床尾坐、刀架的振动频谱的模态表现对加工精度的影响。
The test and analysis results of model for the C6132 type lathe structure are introduced in this paper. Through recognizing the mode parameters and mode of vibration, the pernicious models are looked upon by the respond test analysis of random driver. The paper finally analysies the condition of the different order model frequencies in the vibration frequency spectrum for the tailstock and tool carrier during the different rotational speed.
