Abstract

For dynamically loaded lightweight structures fatigue strength is an important design criteria. In this paper a new method to predict fatigue lifetime is shown. This is based on the combination of frequency domain and time domain calculations, which allow lifetime prediction with reduced computational effort. The method is implemented to work in a concurrent engineering software environment together with a computer aided design (CAD), a finite-element-method (FEM) and a multibody system (MBS) program. The benefits of the new approach are demonstrated by applications to the bogie of a freight locomotive. The dynamic loads acting on the bogie are computed by multibody simultaion. The bogie frame is considered as an elastic body of the MBS and the highly nonlinear wheel rail contact is modeled quasi-elastically. For the ride on a straight track the equations of motion can be linearized and nonlinear differential equations. FEM yields the stresses in the most stressed locations of the bogie prediction is carried out in the MBS post-processing program FATIGUE.
