Side door impact beam is a safety device installed inside the car door, aiming to enhance the vehicle's resistance to side impact accidents and protect the safety of passengers inside. Here are some industry knowledge you should know about side impact beams:
Absorbing Energy and Dissipating Impact Force: Side Door Impact Beam can absorb and dissipate the impact force during an accident, reducing the direct injury to passengers inside.
Strengthening Structure: Improving the rigidity of the car door structure to prevent excessive deformation during an accident.
Material Selection: Common materials include high-strength steel, aluminum alloy, and composite materials. High-strength steel is often used for its high strength and durability, while aluminum alloy and composite materials are also being adopted for their lightweight characteristics.
Structure Design: Typically in the form of tubular or beam structures, some designs use complex cross-section shapes to better absorb energy.
Forming Process: Including hot stamping, cold stamping, and extrusion forming. Hot stamping can effectively improve the strength and toughness of the material.
Welding and Assembly: Impact beams usually need to be welded to the car door frame to ensure a secure connection.
Regulatory Requirements: Different countries have different safety regulations and standards for side impact beams. For example, the European E-NCAP (European New Car Assessment Programme) and the American FMVSS (Federal Motor Vehicle Safety Standards) have specific testing requirements for vehicle side impacts.
Test methods: These include static tests and dynamic tests. Dynamic tests simulate actual collisions and measure impact forces and deformation using sensors to evaluate the performance of the crash bar.
Lightweighting: To improve fuel efficiency and reduce emissions, automakers are looking for lighter materials and structural designs to manufacture Side Door Impact Beam.
Intelligent: Combined with intelligent sensors and active safety systems, providing more comprehensive side impact protection.
Environmentally friendly materials: Using recyclable and environmentally friendly materials to reduce the carbon footprint of production processes.
Side Door Impact Beams are an important component of the passive safety system of a vehicle, and their design and material selection directly affect the vehicle's safety performance. Understanding the industry knowledge of Side Door Impact Beam is helpful in understanding the latest developments and trends in automotive safety technology.
