Research of Front Seat Design Parameters on Rear Seat Passenger in Front Crash

摘要

In order to study the influence of front seat parameters on rear seat passenger when front crash happens, this article uses the MADYMO software to establish the rear seat passenger constraint system model which including car bodies, safety belts and a 5% dummy for impact simulation. The simulation values are close to test ones after contrasted with the vehicle impact test. The influence of design parameters including the front seat headrest and backrest parameters on passenger HIC, T3MS, femur force is researched by this model. With the optimized parameters, the rear passenger head, chest and leg injury are decreased so that the safety of rear passenger can be effectively improved.
