Strength Analysis of Chassis Structure for Medium-Sized Low-Floor Vehicle under Dynamic Load Cases

초록

For the medium-sized low-floor bus, backbone structure of chassis was designed to have light-weight structure with SAPH (Steel Automobile Press Hot rolled) 440. Strength for the designed backbone structure was also analyzed by finite element method under various dynamic load cases considered in this paper. On the basis of the analysis results, the structural safety for the designed backbone structure was evaluated and discussed in this paper.
