Dynamic Analysis of a Full System Durability Test in Vehicle Exhaust Systems 2001-01-1438

A vehicle exhaust system model is implemented into the verified vibration table model. (A dynamic model of the Multi-Axial Simulation Table (MAST) was presented at the SAE 2000 World Congress, Paper No. 2000-01-1187.) The ultimate motivation of this model is to develop and demonstrate advanced dynamic modeling tools in exhaust system design, especially in predicting ‘what if’ situations. The process of the vehicle exhaust system model development is described and the results of a correlation study between the dynamic model analysis, the Full System Durability Test experiments, and the vehicle four-poster tests are presented in this paper. Both sinusoidal and proving ground excitations are used in the experiment. A dynamic model of the rubber isolator is also briefly discussed.
