Abstract: Against the development trend of replacing steel with plastic in automotive interiors, this paper investigates a new cross car beam structure made of steel-plastic hybrid materials. Through product design optimization, application of lightweight materials and simulation-driven optimization, the hybrid beam meets key performance requirements including steering column modal characteristics, dynamic stiffness at steering column mounting points and dynamic stiffness at air conditioning mounting points. Compared with conventional steel cross car beams, it reduces weight by 20%~30%, cuts the number of parts by 80% and shortens assembly time by 65%. The structure achieves significant improvements in weight reduction and assembly efficiency, demonstrating high engineering application value.
