Finite Element Modeling and Analysis for a Certain Urban Bus Frame

Abstract:

Using CATIA set up a 3d model of urban bus frame in this paper, And ANSYS13.0 is used to establish the body frame finite element model of the certain urban bus body frame, Based on this model, the static characteristics under various conditions were analyzed, and the features of stress and strain distribution are gotten. Through the analysis of calculation results, we can conclude that this body frame around the column to the rear windscreen beam junction strength in insufficient, need to increase cross-sectional area of the left column; The floor behind driver seats strength is not enough, need to add two beams to strengthen the support. And the calculation result shows that the rest of the frame has a certain extent optimization space, and can provide the basis for the next step of lightweight.
