摘　　要：采用基于ODS的测试方法对25kJ液压模锻锤机身系统进行试验模态分析,采用Vib’SYS振动信号采集、处理和分析软件,由试验数据识别出机身系统的模态参数及其振型图,找出了机身系统的薄弱环节及需要注意和改进的地方。ODS was used to the body of 25 kJ hydraulic stamp forging hammer by the method of testing modal analysis. Vib＇ SYS collecting, analyzing and processing program processor for sign vibration was applied. Based on testing data modal parameter and vibration chart of body system was identified and the weak sections of the body system and the places which need paying attention to and modifying were found.
