Determination Analysis of the Torsion Beam Suspension FEA Model and Fatigue Strain Based on Road Test

Abstract:

Accurate FEA model of torsion beam suspension and its strain histories are keys to precisely predicting its fatigue life. A strain analysis method is presented, integrating FEA and neural network analysis. The displacement and force histories of the wheel center and strain histories of multiple measurement points on the suspension are measured from road durability test. Apply transient response analysis to determine the FEA model and obtain strain histories of the measurement points. Use a neural network method to obtain accurate additional load. By comparing analysis results and test data, the accurate strain response of torsion beam suspension can be gained
