Modal Testing Analysis and Dynamic Properties Estimate on the Exhaust System of a Medium-sized Bus

摘要：

At the beginning of this paper, we made some brief introductions on the modal analysis theory. In allusion to the vibration conditions of a mediumsized Buss exhaust system, LMS Test.Lab testing software was used and MIMO method was selected to conduct the modal testing. According to the synthesized modal analysis on the X, Y, Z directions of the gauging points, parameters such as the modal frequencies and shapes could be obtained. Then with modal shapes of the first 9 orders, we made some analysis and estimates to the dynamic properties of the exhaust system.
