Abstract:

Based on the deformation characteristics of the bus superstructure in the lateral rollover accident, three kinds of representative waist beam joints were extracted after investigating the joint types for the existing enclosed skeletons and their finite element models were developed accordingly to study the deformation characteristics during the rollover. Then three different joints were implanted separately in the enclosed skeleton and a comparison among the rollover performances was made. A preliminary conclusion about the influence of the rollover characteristics was drawn to provide a reference for the rollover safety design of the bus structure.

Key words: vehicle engineering, bus superstructure, waist beam joint, rollover simulation
