A Car Exhaust System Hook Position Optimization Analysis

Abstract:

Based on the study of a car exhaust system, use HyperMesh Software and its build-in finite element software to build FEM , Analysis the free modal of exhaust system, Calculate its natural frequency, Then optimize the position of hook based on the ways of average degrees of freedom (ADDOFD), Makes its modal frequencies avoiding engine idling frequency. Finally, through the calculated constraint mode, Verify whether coupling with the excitation frequency of engine, and further verify the reasonableness of the position of the hook.
