Abstract
The rear torsion beam of a car was taken as the research object, and its fatigue life was estimated by nominal stress method.In ANSYS Workbench, the strength of the torsion beam was checked through analysis, and the dangerous part and the nominal stress spectrum were obtained. The load time series was obtained in Admas. The SN curve of composite material and fatigue cumulative damage theory were analyzed in ncode Designlife to obtain the fatigue life of the torsion beam. The calculation results show that the minimum fatigue life of the torsion beam is 564,000 kilometers, which is higher than the national number of scrapped cars and meets the use requirements. This method can provide the basis for the optimal design of the torsion beam.Keywords
