| 摘 要： | 本文讨论了研究主轴部件质量分布对其动特性影响规律的模态分析方法,发现质量分布对不同阶次的固有频率和模态柔度的影响存在着较大差异,指出正确调整主轴部件的质量分布,将有助于均化模态柔度在静柔度中所占比重,从而提高机床的切削稳定性。引用实验结果,初步证实了本文的结论。

| Abstract: | The modality analysis method is employed in this paper to study the influence of mass distribution on dynamic characteristics of a spindle system. It is found that there exist obvious difference between the influences of different mass distribution on the natural frequencies . and modality flexbilities of various order-mode. It is shown that the proportion of modality flexbility in the astatic flexbility can be equilibrated by means of adjusting correctly the mass distribution of the spindle system so that the cutting stability is improved as well. Experiment results are quoted to confirm, in a certain degree, the conclusion above. |
