Ensuring the safety and reliability of automotive airbags is a critical aspect of vehicle manufacturing. Airbags are a key component of a vehicle's passive safety system, designed to protect passengers during a collision. To guarantee their effectiveness, rigorous testing of airbags is essential before they are installed in vehicles.
Airbags are a crucial safety feature in modern vehicles, providing a cushion to protect passengers during a crash. According to the National Highway Traffic Safety Administration (NHTSA), frontal airbags saved 50,457 lives from 1987 to 2017. With the majority of car accidents involving frontal impacts, the testing of front airbag systems is particularly vital.
Airbags are typically made from a combination of rubber and nylon, forming a laminated film that must rapidly inflate with gas during deployment. The Labthink DM 2/330 Gas Permeability Tester is an advanced instrument capable of assessing the permeation properties of airbag materials. It can test under differential and equal pressure conditions, accommodating three samples at once, and is suitable for a range of gases, including hazardous ones. The temperature control feature allows for testing across a broad range of conditions, simulating both storage and activation environments.
The smoothness and ease of deployment are critical for airbag performance. Labthink Instruments Co. Ltd offers the MXD Series of Coefficient of Friction Testers to evaluate the static and kinetic friction of materials, ensuring the airbag unfolds correctly. The FTP-F1 Friction/Peel Tester further assesses the material's friction coefficient and peel strength, which are essential for proper airbag function.
Airbags must withstand significant forces during deployment and protect passengers from impact. Labthink's PARAM XLW Series Auto Tensile Testers evaluate tensile strength, deformation, and other mechanical properties of airbag materials. For impact resistance, the BMC-B1 Falling Dart Impact Tester is used to measure the material's strength against tearing, adhering to standards such as ASTM D 1709 and JIS K 7124.
Airtight sealing is crucial for airbag inflation. The PARAM MFY-01 Leak Tester from Labthink Instruments Co., Ltd. checks for leaks by submerging the airbag in water and applying pressure. This tester is user-friendly, computer-controlled, and provides precise data in compliance with ASTM D3078 and GB/T 15171.
The bond between the nylon and rubber layers of an airbag must remain intact over time to ensure proper inflation. The PARAM XLW series of auto tensile testers from Labthink Instruments Co. Ltd. is designed to test the peeling strength of these materials, offering computer control and professional software to deliver reliable results in line with ASTM, ISO, JIS, and GB standards.
Automotive airbag testing is a sophisticated process that requires specialized instruments to ensure the safety and reliability of these life-saving devices. With advancements in testing technology, manufacturers can continue to improve airbag performance and passenger protection.
