提高刨床动态测试数据精度的研究

Studies of improving planer tested data precision

主要对提高刨床动态测试数据精度的方法进行了研究。一般工厂不具备先进测试仪器 ,而且现场中常用的脉冲激励方法有很多不足之外。在模态分析前 ,通过时域平均处理及加指数窗等方法来提高信噪比和数据精度。

The paper mainly studied the way of improving planer dynamic test data precision.The common pulse exciter ways have many shortcomings in the field.It improved the signal to noise ratio and data precision by the ways of time domain average processing and adding index window before model analysis.
