Description

TECHNICAL FIELD

[0001] The application belongs to the field of device safety airbag testing, and particularly relates to a comprehensive test test bed for automobile safety airbags. BACKGROUND

[0002] Under the vigorous and rapid development of the global automobile industry, the automobile population continues to rise, and the road traffic environment is becoming increasingly complex. At the same time, consumers' safety awareness has significantly increased, and their expectations for the safety performance of automobiles have reached an unprecedented height. As a core component of the passive safety system of vehicles, the importance of automobile safety airbags is self-evident. In the instant of a vehicle collision, the safety airbag needs to complete the inflation and deployment action at an extremely fast speed, and build a buffer barrier between the passenger and the hard components in the vehicle, effectively absorbing the energy generated by the collision, thereby greatly reducing the probability of the passenger suffering serious injuries. However, upon examining the current airbag testing field, the traditional testing methods have exposed many limitations. On the one hand, traditional testing often focuses only on a single detection item. Taking the tensile test as an example, its main purpose is to evaluate the mechanical properties of the airbag material under tensile force, such as the tensile strength and elongation at break of the material. However, it is difficult to fully understand the performance of the airbag under complex stress conditions in the actual collision scenario based on the tensile test results alone. The same is true for the tear test. Although the tear test can reflect the airbag material's ability to resist tearing to some extent, it cannot cover various complex deformation conditions such as bending and twisting that the airbag may face during the inflation and deployment process, and thus cannot fully present the comprehensive performance of the airbag. On the other hand, the traditional testing equipment has obvious deficiencies in the impact test. In actual vehicle collision accidents, the collision angle and direction have great uncertainty, which can come from the front, side, rear, or even multiple directions. However, when performing impact tests, traditional testing equipment can only achieve fixed-position impact on the airbag. For example, common front impact testing equipment can only simulate a single working condition in the case of a vehicle frontal collision, and cannot accurately reproduce the impact conditions of multiple angles and directions in reality. The limitations of this testing method result in a large deviation between the test data obtained and the actual performance of the airbag in the real collision scenario, seriously affecting the accuracy of the airbag quality evaluation, and thus making it difficult to provide highly valuable data support in the development, production, and quality control process of the airbag. In view of the above problems, in order to meet the stringent requirements of the automobile industry for high-performance and high-reliability safety airbags, and to ensure the safety and competitiveness of products in the fierce market competition, the industry urgently needs a test bed that can break through the traditional testing bottlenecks and achieve comprehensive and efficient testing of automobile safety airbags.
