Optimization of Passenger Restraint System of a Production SUV Based on Automobile Frontal Impact Protection

Abstract

Abstract:

The frontal impact restraint system model of a production sport utility vehicle(SUV) was developed and validated. Based on this model, the orthogonal experimental design and computational simulation were conducted and optimized parameters of the system were obtained. The passenger restraint system was improved and the sled test was conducted. The results show that the improved system has better protection performance in frontal crash.
