Abstract

The invention relates to an automobile testing device, in particular relates to an airbag head hammer falling static testing device. The head hammer is oriented by rolling a roller wheel on a guide track so as to control the impact point of the head hammer; the elevating height of the head hammer is controlled automatically so as to ensure the speed of impacting the airbag; the explosion of the airbag and the separation of the head hammer from a suspension frame mechanism are controlled automatically, so that the influence of the suspension frame mechanism to the collision response is eliminated; the suspension frame mechanism can adjust the position of the head hammer at the front, the back, the left and the right; and the airbag adjusting mechanism can adjust the inclination angle and the front and the back positions of the airbag. The impact angle and the position of the head hammer to the airbag are adjustable; and the quality of an impact object can be controlled; the collision position, the angle and the mass of the object are ensured to accord with a corresponding automobile model; and the test is good in repeatability effect.

Description

technical field [0001] The invention mainly relates to an automobile safety test device, in particular to a safety airbag static test device. Background technique [0002] When the car collides and reaches a certain collision intensity, the airbag will generate a large amount of gas in a very short time to inflate the airbag. When the vehicle occupant's head and chest are in contact with the air bag, the air bag should be fully inflated and deployed with a certain support stiffness, so as to generate an evenly dispersed force on the occupant's head and chest, and absorb it through the throttling damping of the air bag vent hole. Collision energy, ease the impact of the occupant, reduce occupant injury. The protection effect of the airbag on the occupant depends on whether its performance parameters are reasonable. Therefore, for different car models, it is necessary to set the airbag performance parameters suitable for the car model. At present, the research and matching ...
