Abstract

The invention discloses an airbag linear impact test platform and a test method thereof. The airbag linear impact test platform comprises a pneumatic device module, an airbag linear impact module, an airbag installation module, an airbag to be tested, a coordinate plate and a test bench, and is characterized in that a photoelectric speed sensor and two high-speed cameras are further installed on the test bench. The test method comprises the steps of 1) adjusting the test platform to an initial state; 2) installing the airbag to be tested on an airbag installation mold; 3) adjusting a pressure adjusting valve to the set pressure; 4) starting a pneumatic pump; 5) pushing an impact block by a piston cylinder; 6) recording the whole unfolding process of the airbag; 7) detecting a contact force between the impact block and the airbag to be tested through an acceleration sensor; 8) carrying out analysis and signal processing on recorded data; and 9) finally, acquiring dynamic characteristic parameters of the airbag to be tested. According to the invention, dynamic characteristics of the airbag in the impact process can be measured effectively, thereby improving the test accuracy.

Description

technical field [0001] The invention relates to a safety airbag test platform, which belongs to the technical field of auto parts testing, in particular to a safety airbag linear impact test platform and a test method. Background technique [0002] Common airbags on automobiles can be divided into driver airbag DAB, passenger airbag PAB, side airbag SAB, knee airbag KAB and air curtain CAB. In the research and development stage of the airbag, it is necessary to obtain the dynamic characteristics of the airbag through experiments, and the automobile airbag is mainly researched and developed through the combination of experiment and simulation. The experiment can provide comparison for the simulation results to verify the accuracy and accuracy of the airbag simulation model. Effectiveness, used for simulation benchmarking of airbag components. According to the type of airbag, the airbag test can be divided into driver airbag test, copilot airbag test, knee airbag test, side...
