Development of Model Simplifications of Bus Body Connections

The simplifications for connections between beams of body frame, although is not enough to affect the stress distribution of the whole bus body frame, is still very important for local stress distribution, especially for stress concentration regions. In this paper, with electronic test technique and the FEM software ANSYS, according to the real structure, we use different ways to simplify the connections to acquire the optimum simplified way and higher calculation accuracy.
