BIW Safety Performance Research Based on Vehicle Frontal Crash

This paper introduces the research course of vehicle crash safety performance. A vehicle frontal crash FEA model is established according to CMVDR294. Vehicle frontal crash simulation calculation is conducted by LS-DYNA. Energy absorption area and transmission route of impact force in frontal crash are introduced in details. Affects of longitudinal beams deformation on vehicle crashworthiness are discussed deeply through simulation of the longitudinal beams design plan. Finally, tests are made to verify feasibility of the longitudinal beams design plan and reliability of the vehicle frontal crash model. As result, references are provided for vehicle longitudinal beams design and improvement for the future.
