A Device and Test Methodology for Side Impact Crash Simulation Using A Frontal Crash Simulator and Two Hydraulic Brake Systems 2000-01-0047
Occupant protection in the side impact of a car became one of the most important issues of the car crashworthiness due to high injury level in a side impact crash. An accurate simulation of the side impact crash is an essential tool for the reduction of development time and cost for side impact safety system. This paper describes a new test methodology that can accurately generate the crash pulses of the vehicle and the door in a very cost-effective manner, and then evaluates the injury values of the dummy for various sled pulses. This test methodology is simple and easy to approach because the door velocity is controlled by the hydraulic actuator and brake, and the seat velocity is only adjusted by friction force of the hydraulic brake. The superiority of the proposed test methodology is proven by correlation with test.
