Description

technical field

[0001] The invention relates to a device for detecting the stiffness of an automobile safety airbag, which belongs to the technical field of automobile parts detection. Background technique

[0002] As an auxiliary configuration for the passive safety of the vehicle body, the airbag has been paid more and more attention by people. When the car collides with an obstacle, it is called a primary collision, and when the occupant collides with the internal components of the vehicle, it is called a secondary collision. When moving, it "flutters on the air cushion" to ease the impact on the occupant and absorb the collision energy, reducing the degree of injury of the occupant.

[0003] Car airbags also have their unsafe side. According to calculations, if the car is traveling at a speed of 60km / h, a sudden impact will stop the vehicle within 0.2 seconds, and the airbag will pop out at a speed of about 300km / h, and the resulting impact force will be about 180kg. ...
