Abstract

The study of coach welded structures durability based on the tests and FEM Numerical simulation was carried out. First, the tension-compression fatigue tests with welded joints were carried out. The steel S-N curves which will be used in the FEA fatigue analysis were gained; The finite element models of weld structure has been built and the fatigue analysis of welded joints were taken out, the comparison between fatigue test results and the FEA simulation results was performed, the results of both methods showed very closed and the verification of FEA weld seam model which was built in the FEA; Finally, the FEA model of coach with welded joints has been established, the number of seam welds reached at 3870, the fatigue analysis of the whole coach has been carried out. The research can be used for coach or bus fatigue analysis of high cycle in welded joints of profiles with thin wall tubes.
