摘要
高速加工能显著地提高生产率、降低生产本钱和提高产品加工质量，是制造业进展的重要趋势，也是一项超级有前景的先进制造技术。实现高速加工的首要条件是高质量的高速机床，而高速机床的核心部件是高速电主轴单元，它实现了机床的“零传动”，简化了结构，提高了机床的动态响应速度，是一种新型的机械结构形式，其性能好坏在专门大程度上决定了整台机床的加工精度和生产效率。
在主轴的动态参数中，振动是最重要的问题之一，包括了丰硕的运行状态信息，是一个动态状态信息库。因此对高速电主轴进行振动分析相当重要。
本文要紧介绍了高速电主轴的振动机理及相关的防治方法，提出了高速电主轴的检测方式，介绍了虚拟仪器Labview及其仿真进程。并通过仿真结果对不同因素的振动阻碍进行了直观描述，对前述的理论分析进行了验证。

ABSTRACT
High speed machining(HSM)has become the mainstream of manufacturing for drastically
increasing productivity,reducing production costs and improving the product quality.HSM is also a promising advanced manufacturing technology.In the realization of HSM,machine tool generally plays an all-important role and high speed motorized spindle is the key technology for a machine tool.The machine tool equipped with high speed motorized spindle has characteristic of the zero-transmission and simplified of the machine structure.With use of new mechanical structure,the high speed motorized spindle has much better dynamic performance in response to the high demands in this machine.In general,overall performance of high speed machine in terms of the machining precision and productivity is largely dependent upon the performance of the 郑爽整容了吗equipped high speed motorized spindle.
It is storeroom in the dynamic problem of the machine tool which include many information of the dynamic movement on the equipment. So it is very important to analysis the vibration of high-speed electric spindle.
This article mainly introduced vibration mechanism and preventing measures of the high-
speed electric spindle.It proposes the detection method of high-speed electric spindle and introduces the Labview virtual instrument and its simulation process. Through the simulation results we make intuitionistic description for  the influence of vibration ,in different factors and validate the  foregoing theoretical analysis.
Keywords: high-speed electric spindle, Labview simulation, vibration analysis, Virtual instrument testing
