Abstract

The passenger protection performance of seat belts in special-purpose vehicles subjected to vertical shocks has rarely been studied. This paper describes numerical simulations of the vertical shock response of seat-passenger systems equipped with 5 different types of safety belts. Anchoring systems of 5 or 6 anchor-point belts are optimized to improve the protection under strong performance vertical shocks, and the influences of the anchoring configuration changes for the two types of safety belts also numerically analyzed for frontal and lateral collisions. The results show the remarkable influence of the configuration of multi-anchor-point safety belts on the passenger protection performance and the optimized anchoring systems of safety belts significantly improve the passenger's vertical shock protection. The study gives a comprehensive optimal design method for safety belt systems of special-purpose vehicles.
