Analysis of key technology in fatigue simulation experiment of torsion beam

摘要

Torsion beam is a kind of automobile suspension system. At present, bench experiment is a widely used method to predict the fatigue torsion life of torsion beam in the research and development process of torsion beam, so the accuracy of experiment results is particularly important. According to the actual load condition of torsion beam, this paper builds the corresponding experiment bench, and analyzes the key technologies in the process of bench experiment and adjustment. The experiment results show that the application of the key technology can restore the entry point, force direction and load of the vehicle in the real driving process.
