Abstract

Reducing the weight and production cost of chassis is considered to be one of the most important area of research in automotive manufacturing industry. However with lighter vehicle, the chassis is easily subjected to large vibration mainly coming from the engine and road irregularities. This paper looks into the application of dynamic analysis for verification of the complex FE model of truck chassis. The dynamic characteristic of truck chassis such as the natural frequency and mode shape is determined by finite element method. Experimental measurement by modal testing is then carried out to determine the accuracy of finite element analysis. Initial result indicated some discrepancies with regard to natural frequencies at various modes. However for mode shape analysis, both methods produced almost the same shape. As for getting a better agreement between both methods of analysis, modal updating had been carried out. The results show that the error was reduced to ± 2% through the model updating.
