摘要
建立了一种新型结构的高速精密主轴单元的振动分析模型,定量研究了直线轴承支承对主轴轴系的径向振动特性的影响,得到了若干具有实际意义的研究结果。
The vibration analysis model of a new high-speed spindle is founded in this paper. By analyzing the influence on the high-speed spindle's radial vibration characteristic, which is caused by using the linear bearing in the structural design of the high-speed spindle, the invaluable results are acquired.
