本文以实验模态分析理论为依据,采用单输入/单输出,即SISO正弦激振方法对简易立式加工中心机床进行激振试验,在7T08信号分析仪上进行数据处理和模态参数识别。试验获得了危险振型,找到了薄弱环节。
Based on the experimental modal analysis theory, single-input / single-output (SISO) sinusoidal excitation method is used to test the vibration of a simple vertical machining center machine. Data processing and modal parameter identification are performed on the 7T08 signal analyzer. The experiment got the dangerous vibration mode and found the weak link.
