安全气囊系统(国外英文资料) Airbag system (SRS) I. Preface The driver and passenger injury in order to reduce the vehicle frontal collision due to huge inertia force caused by the modern car in the front wheel with a common central driver airbag system, some cars are equipped with safety air bag system in the drivers seat before the upper side toolbox. The experiment and practice have proved that when the automobile is equipped with the airbag system, the frontal crash of the car will greatly reduce the damage to the driver and the crew. Some cars are equipped with front airbags as well as side airbags, which allow lateral airbags to be inflated during lateral collisions to minimize side impact damage. Two. The working principle of the airbag system When the car is involved in a head-on collision, the airbag control system to detect the impact (deceleration) exceeds the set value, the airbag computer connected immediately in electrical circuit components pneumatic pipe explosion ignited ignition electric blasting medium tube, flame ignition powder and gas generating agent, produce a lot of gas, in 0. 03 seconds to the air, the air bag expands rapidly, break through the steering wheel decorative cover drum to the driver and the passenger, the driver and the passengers head and chest pressure in the air bag filled with gas, the impact of buffer to drivers and passengers, then release the air in the air bag. Three. Composition of airbag system Airbag system mainly consists of collision sensors, airbags, computers, SRS lights and airbag components of four parts. 1 、 collision sensor Collision sensor is the main control signal input device in airbag system. It is in the car collision, the collision detection signal strength sensor of vehicle collision, and the signal input airbag computer, the airbag computer according to the signal collision sensor to determine whether the inflatable element is inflated to detonate. Airbag system is generally equipped with 2~4 collision sensors, fr
