Abstract

The invention discloses a occupant restraint system optimization method based on energy analysis. The occupant restraint system optimization method based on energy analysis comprises the following steps: firstly, establishing a frontal collision model of a A-class vehicle, and verifying the effectiveness by the method of simulation and experiment; then, analyzing the energy absorption condition of each restraint subsystem combined with the energy theory and based on the energy transfer mode of the occupant, and obtaining the restraint system energy distribution curve; and then finding out the relationship between the energy distribution of the restraint system and the occupant weighted injury criterion (WIC); finally, analyzing the parameters of each restraint subsystem, and constructing the relationship between the parameters and the energy distribution of the restraint system, so as to adjust the relevant parameters and realize the performance optimization for occupant protection of the restraint system. The invention has great significance for improving the protection performance of the occupant restraint system and shortening the optimization period.

Description

technical field

[0001] The invention belongs to the field of automobile safety, and in particular relates to an optimization method for an occupant restraint system based on energy analysis. Background technique

[0002] Vehicle frontal collision is the most common form of collision in traffic accidents. In the process of frontal collision, the occupant restraint system has a significant protective effect on the occupant, and the research on its performance is very necessary. At present, the occupant damage value is mainly used as the evaluation basis to optimize the restraint system. However, there are many uncertain factors in the occupants themselves, and the steps to evaluate the restraint system indirectly are cumbersome and imprecise. Therefore, from the perspective of energy, the energy absorption of each restraint subsystem can be analyzed, and the relationship between the energy distribution of the restraint system and the protection of the occupants can be found ...
