Research on the Intelligent Rear Under-run Protection System for Trucks
In collisions with trucks, there is a high risk for car occupants to sustain severe or fatal injuries. The intelligent rear under-run protection system, as a very important part to prevent under-run accidents and decrease loss, its dynamic deformation and stress distribution mostly lie on the characteristic of energy absorber and keeping directional stability of the rear vehicle during collision. In this paper, based on the related actuality in China and abroad, an intelligent rear under-run protection system with integrated function is presented and the key structure is systematically given. Then taking a car as an example, the whole process of under-run collision is simulated and analyzed by applying nonlinear FE program. Simultaneously, the time histories of collision force of the key support structure and velocity variation are presented. All of these can be worth using as references in related fields.
