Abstract

In some typical bus accidents, the causes of passenger injury have presented some common characteristics, which makes it necessary to improve the design of bus. In general, bus traffic accidents can be divided into two typical forms: emergency braking and rollover, both of which could seriously threaten the life security of passengers. In this article, these two kinds of bus accident are studied through numerical simulation and some improving suggestions on bus design and manufacture are given. According to simulation results, passengers may suffer from serious hurt due to emergency braking acceleration and deformation of bus body caused by the impact with highway guardrail. Improving measures include equipping seats with three-point belts, adding board on the handrail and enhancing the material and structure of side uprights of the bus. Simulation results show that these improving measures can provide better protection for the passengers involving bus traffic accidents, which has verified the rationality of these measures.
