RESEARCH ON VIBRATION FATIGUE LIFE OF VEHICLE EXHAUST SYSTEM UNDER TEMPERATURE FIELD DISTRIBUTION

Aiming at analyzing the influence of thermal load and mechanical load on the vibration characteristics and fatigue life of the exhaust system,the finite element model and modal test were conducted by modal analysis. The temperature field distribution of the exhaust system was obtained via CFD analys...
