Optimization and Validation of PAB to the Front Row HIII 5th Percentile Female Occupant Restraints System

摘要

There are more and more female passengers presently. How to protect the safety of female passengers effectively is a problem to be solved. The study in this paper is based on the safety of 5th percentile female in Euro-NCAP full frontal impact test. This paper studied the restraint performance of front row 5th percentile female through built and correlated the CAE models with MADYMO to analysis the restraint performance, optimize the parameter of passenger airbag. The single stage passenger airbag, tether passenger airbag and double stage passenger airbag are used in the sled tests individually. The study shows that the single stage passenger airbag decrease effectively the injury of the front row 5th percentile female by optimize the type, the manner of fold and the method of pre-sew, tether passenger airbag alleviate effectively the head deflection injury of the front row 5th percentile female, double stage passenger airbag resolve effectively the chest injury risk of the front row 5th percentile female. Restraint system sled test is quickly and availability method to develop and validate the passenger airbag in the project, then laid a foundation for the following restraint system development.
