Development of a Strength Prediction Technique for Automotive Exhaust Systems

Article of Honda R&D Technical Review Vol.12 No.2


A technique has been devised for predicting the strength of an automotive exhaust system in relation to the rotational force input from the torque reaction force of the engine.
Conventional static analysis conducted using the Finite Element Method (FEM) has been replaced by techniques for dynamic analysis that treat the force input accompanying large transient displacement as a forced displacement, and techniques that take into account the nonlinear nature of mounting rubbers, flexible joints, and so on. As a result, it has become possible to predict the strength of exhaust systems with greater accuracy, and to apply these techniques as development support tools.
