Abstract
The current advanced airbag regulation (FMVSS208) requires passenger cars and MPV either to have an automatic suppression system or to meet the LRD requirement on the passenger side. Recently, the car makers are choosing LRD requirement option and developing new LRD passenger airbag system. This paper presents a new methodology for improvement of airbag deployment using experimental and analytical research. The significant parameters were determined from statistical analysis of the experiment data. Basically, to deploy airbag normally, the ultra sonic knife or laser is used to cut the skin layer inside along with the gate line partially, so that deploying airbag can tear gate on instrument panel surface easily. As a result of the number of tests conducted at different conditions, this study was able to determine the range of relevant parameters. Additionally, using LRD simulation model, a parametric study was done, to figure out, which design factors mainly affect the low risk deployment of the passenger airbag, and some design improvements are presented.
