Investigation of Pressure Rise in Automotive Airbags
Safety is a widely spread topic in engineering, from specific producing processes to everyday life. Innovation of passenger cars belongs to the frontline of industrial sector. Higher and higher performance motors, more streamlined vehicle dynamics, more reliable autonomous vehicles, and minor noise and vibration are the most expected developments what customers prefer. However, it is not allowed to forget automotive safety, which effectiveness prevents fatalities to drivers and passengers.
A very important part of this safety system are the airbags. Frontal airbags aim at preventing serious injuries from impacts of the driver’s or passenger’s head or upper body against the steering wheel or other parts of the vehicle. Worldwide almost every vehicle produced with frontal or front-seat passenger airbags. Their improvement and investigation of operation is a main role of production. Pressure rise and gas temperature in bladders are significant information related to their operating mechanism.
Many investigations can be found in literature which describe the occurring processes during the explosion. Most of them are computational or experimental ones, and others sets up mathematical models. This paper presents options of modelling pressure rise in automotive airbags and inflators.
