用脉冲激振法识别超精密金刚石车床的动态特性

Identification of Dynamical Behavior of Ultra-precision Diamond Tool Lathe with Impulse Excitation Method

用脉冲激振方法识别了 MSG—325双轴数控金刚石车床的传递函数。机床动态特性参数用复模态方法识别。为了考证被测试验结果的可靠性。运用随机激振方法进行校核。

In this paper,the impulse excitation method was applied in iden- tifying the transfer function of MSG-325 2-axis CNC Diamond Tool Lathe,its dynamical behaviors parameters were identified by complex modal method.In order to examine the reliability of measured test results,the verifying tests were carried out with the random excita- tion method.
