NiYo Engineers’ Vehicle Air Bag Simulator Trainer is designed for students to understand the basics of an automobile air bag system. All the components of the air bag system of a car are mounted on a representative chassis. A simulator is provided for generating the effect of an impact. Upon impact the bags inflate and open up. Either compressed air is used to inflate the bag or an original canister is used for inflation. The canister based inflating bag has a higher operating cost.
