Engineering Design - CAE

Employing computer simulation as an analytical tool for airbag product design and safety analysis can partially replace automotive crash testing, thereby enhancing efficiency, reducing costs, and shortening the development cycle. The CAE Simulation Team, based on the 3D digital models provided by automakers, uses the occupant injury simulation software MADYMO to build dynamic simulation models of vehicle crash occupant restraint systems. These models include both frontal occupant restraint system analyses and side occupant restraint system analyses. By leveraging the validated simulation models, engineers can optimize airbag designs—specifically targeting types such as the Driver's Airbag (DAB) for frontal deployment and the Passenger Airbag (PAB) for side-impact scenarios.

Product Description

　　Employing computer simulation as an analytical tool for airbag product design and safety analysis can partially replace automotive crash tests, thereby enhancing efficiency, reducing costs, and shortening the development cycle. The CAE Simulation Team, based on the 3D digital models provided by automakers, uses the occupant injury simulation software MADYMO to build dynamic simulation models of vehicle crash occupant restraint systems. These models include analyses of both frontal and side occupant restraint systems. Once the validated simulation models are established, they can be used to optimize the design of airbags—covering types such as the Driver Airbag (DAB), Passenger Airbag (PAB), Side Airbag (SAB), and Curtain Airbag (CAB). By refining airbag designs through this optimization process, manufacturers can improve the effectiveness of airbags in protecting occupants, while also providing valuable guidance for the development of next-generation airbag technologies.

Steering Wheel and DAB

The Driver Airbag (DAB) is a facial protection device installed in the driver's steering wheel. Specifically, it is a 55-liter facial protection airbag mounted via a snap-in structure inside the steering wheel. When used in conjunction with the vehicle's seat belt, it can reduce the degree of injury to the driver's head and face. Compared with other airbags, it boasts advantages such as lower development costs and shorter development cycles. Additionally, it features a platform-based structure, which can adapt to different vehicle models with only minor modifications.

Decorative Cover

The Driver AirBag (DAB) cover is made of high-performance thermoplastic elastomer (TPO) through precision injection molding. Co-designed with the vehicle’s interior styling, it features specific pre-formed tear lines to ensure timely and smooth airbag deployment, combining aesthetics and functionality.

Chery E01 SW Assembly

The steering wheel of the Chery E01 is wrapped in premium microfiber leather, with the secondary foaming process achieving a two-tone exterior design. It is applicable for the Chery Fengyun A9L model.Equipped with HOD (Hand on Detection) and heating functions, the HOD adopts a three-zone capacitive sensing solution, delivering accurate and sensitive response.The steering wheel frame is made of lightweight die-cast aluminum-magnesium alloy with excellent dynamic performance, combining high strength and lightweight properties.

Geely E22H-R

Automotive side airbags are designed to protect the occupant's torso during a side collision. When side impact sensors detect an impact of sufficient force, the control unit rapidly triggers the gas generator within the airbag module. The solid propellant is ignited, producing a large volume of harmless nitrogen gas that inflates and deploys the airbag in approximately 20 milliseconds. This forms a cushioning barrier between the occupant and the rigid door structure, effectively dispersing and absorbing impact energy to reduce the risk of injuries to the ribs, internal organs, and pelvis.
