一、引言机床在加工时,既要保证达到一定的精度和光洁度,又要有较高的生产效率,这就要求整机具有良好的动态性能。整机的动态性能是由各部件的综合决定的,而机床主轴部件是机床最关键的部件,其动态性能的好坏,很大程度上直接影响整机的动态性能。众所周知,机床主轴部件的静态特性是以机床主轴端部的静刚度表示的;而其抗振
I. INTRODUCTION Machine tool in processing, it is necessary to ensure that a certain degree of accuracy and finish, but also have a higher production efficiency, which requires the machine has good dynamic performance. The dynamic performance of the whole machine is determined by the synthesis of the various components. The main components of the machine tool are the most critical components of the machine tool. The dynamic performance of the whole machine directly affects the dynamic performance of the whole machine directly. It is well known that the static characteristics of the spindle components of the machine tool are expressed by the static stiffness at the end of the spindle of the machine tool.
