The conception of smart materials and structures is firstly combined with research of air bag, and the main theory of self-adapting cushioning of intelligent air bag is expatiated. The intelligent venting structure is the main part affecting the cushioning result. Electrostrictive material was found having big force, high response speed and wide linearity, and it is fit to utilize in intelligent venting structure. The characteristic of the dynamic response and cushioning actuating of an electrostrictive stack actuator is analyzed, and the result of the computer simulation of the fuzzy control to intelligent venting structure is given. It is concluded that intelligent venting structure has good actuating characteristic and can satisfy the need of intelligent air bag.
