Dynamic Modeling of an Independent Wheelset Bogie with MapleSim

Abstract:

In order to help researchers better understand the dynamic characteristic of independent wheelset rail vehicles, this article presents a new modeling way to establish an independent wheelset bogie with a white-box dynamic analysis tool-MapleSim. In this article, an independent wheelset model is made firstly. Than based on this wheelset model, an independent wheelset bogie is made. After the modeling, the necessary validation with Simpack is done. The straight line dynamic validation includes the creepage of left and right wheels, the lateral displacements of bogie and both wheelsets’ yaw and lateral displacements. The results are similar to the model with the same parameters in Simpack which reveals that the bogie model in this article is correct and feasible.
