Research on Vibration Test Method of the Whole NC Machine Tool

摘要

Vibration test of the whole machine has become an important measure to solve vibration problem of NC machine tool, because it can evaluate anti-vibration performance and check the validity of vibration analysis. In the paper, on basis of confirming the vibration test contents for NC machine tool, the vibration test method and flow of the whole machine are proposed from the need of engineering, which include planning experiment instruments, confirming test contents, putting up test system, vibration test, analyzing experiment data etc. At last, taking a NC boring machine which is built by Shenyang machine tool group as study case, the whole machine vibration test is done. The practice indicates that the method is effectual.
