For vehicle structural fatigue life issues considered in the design, fatigue analysis of key parts of the vehicle based on road test and CAE (Computer Aided Engineering) simulation techniques is presented. The rear torsion beam of a vehicle can be used as an example. Firstly, the unit load stress field is calculated by the principle of inertia release after the establishment of the torsion beam finite element model; Then, establishing vehicle rigid coupling model, and making six-component test site collection wheel center as a multi-body simulation input, torsion beam rear obtain the required load spectrum of fatigue analysis; The ground test data is provided for verifying the reliability of the model and the modified model parameters; Finally, Stress influence coefficient method is used for the torsion beam fatigue life prediction. What’s more, simulation results are compared with the road test results. The results show that this method can ensure the accuracy of the finite element model for fatigue analysis and boundary conditions, so that the fatigue life of the torsion beam rear car simulation analysis is more accurate. Provides a theoretical basis for fatigue analysis based on the structural design and Improvement of the rear torsion beam of vehicle. The method is also applicable to the fatigue analysis of other vehicle parts.

Background:: In the process of high-speed driving, the wheel hub is constantly subjected to the impact load from the ground. Therefore, it is important to estimate the fatigue life of the hub in the design and production process. Objective:: This paper introduces a method to study the fatigue life of car hub based on the road load collected from test site. Methods:: Based on interval analysis, the distribution characteristics of load spectrum are analyzed. The fatigue life estimation of one - dimensional and two - dimensional load spectra is compared by compiling load spectra. Results:: According to the S-N curve cluster and the one-dimensional program load spectrum, the estimated range fatigue life of the hub is 397,100 km to 529,700 km. For unsymmetrical cyclic loading, each level means and amplitude of load were obtained through the Goodman fatigue empirical formula, and then according to S-N curve clusters in the upper and lower curves and two-dimensional program load spectrum, estimates the fatigue life of wheel hub of the interval is 329900 km to 435200 km, than one-dimensional load spectrum fatigue life was reduced by 16.9% - 17.8%. Conclusion:: This paper lays a foundation for the prediction of fatigue life and the bench test of fatigue durability of auto parts subjected to complex and variable random loads. At the same time, the research method can also be used to estimate the fatigue life of other bearing parts or high-speed moving parts and assemblies.
