摘　　要： 利用环境激励作为激励振源,测试了一复杂结构的脉动响应信号,并利用工程振动反演理论分析得到了该结构的固有频率、振型、阻尼比等动力特性。X、Y向基频及X、Y向第一振型与理论计算值吻合较好,X、Y向基频对应的阻尼比约为3.4%。 This paper(report) presents the method to test the pulsing response signal of the complicated structure by using external stimulation as the vibration source.The dynamic characters of natural frequency,vibration mode,damping ratio etc.of the structure can be derived based on Vibration Reverse Theory.The results showed that the natural frequency and first mode in X and Y direction are well agree with the theoretical results with the corresponding damping ratio resulted at about 3.4 percent.
