Vehicle safety has become an important indicator in the automotive industry,especially with the increasingly stringent requirements of safety regulations,C-NCAP,C-IASI and other related standards,the protection requirements for the right side passengers are also becoming higher and higher.In order to meet stricter regulatory requirements and achieve higher star of safety levels,the volume of airbag and the energy of gas generator have been correspondingly increased,which puts higher requirements on the structure of interior components that related to airbag explosion.Based on the situation of the co-driver airbag explosion test in previous development projects,this article introduces the common concept of passenger side airbag,and takes the U-shaped airbag door as an example to discuss the common failure modes and related solutions of the instrument panel in the airbag test.so as to provide relevant reference information for subsequent project development.The following technical suggestions can be reserved in advance at the design stage to avoid repeated test and mold modification in the physical stage,which will affect the project schedule and cost.
