介绍了一种高速主轴性能的测试实验。采用DHDAS动态信号测试分析系统,在高速主轴工作状态下,采集不同转速下主轴两端的振动加速度信号,并利用仪器自带的分析软件以及MATLAB软件,对所得数据进行平滑、消除趋势项、积分变换等分析处理,提取了真实有效的信息,为高速主轴性能的研究和分析提供了依据。结果表明,该实验方法,实时高效,且抗干扰能力强,误差较小,是研究高速主轴振动特性的有效方法。
A high speed spindle performance test is introduced. Using DHDAS dynamic signal test and analysis system, under high-speed spindle working state, the vibration acceleration signal of the spindle at different rotational speeds is collected, and the instrument’s own analysis software and MATLAB software are used to smooth the obtained data and eliminate the trend term, integral transform And other analysis and processing, extract the real and effective information for high-speed spindle performance research and analysis provide the basis. The experimental results show that the proposed method is effective and real-time with high anti-interference ability and small error. It is an effective method to study the vibration characteristics of high-speed spindle.
