Occupant Risk Evaluation Based on Frontal Collision of Bus

This article took the type of 6900 passenger car as an object reference, referred protection of the occupants in the event of a frontal collision (ECE R94) and protection of the occupants of the cab of commercial vehicles (ECE R29). Through the analysis of the initial energy when the bus was collision and took advantage of the software LS-DYNA to analyze the impact tests of pendulum and fixed barrier wall, respectively. By calculated the displacement and acceleration of the framework, it determined using the frontal collision evaluation was reasonable. On this basis, it selected the collision speed-30 km/h to conduct the frontal passenger crash test in real vehicle that of fixed barrier wall. And then, it analyzed the impact of two-point and three-point seat belts harness on the bus occupant safety. The results showed that: the three-point seat belt protection was better than two-point seat belts, so the three-point seat belts arrangement should be installed on buses, possibly.
