摘 要：Carbon Fiber Reinforced Plastics（CFRP） have the advantages of low density,high strength,corrosion resistance,*** the improvement of CFRP manufacturing and processing technology,CFRP have been increasingly used in the automotive *** this paper,based on a vehicle model with CFRP body structure,the research of multi condition vehicle crash safety simulation technology is carried ***,study the CFRP vehicle modelling ***,calibrate the constitutive of CFRP and structural glue,obtained characteristics parameter through a series of sample-level and component-level tests and ***,the CFRP vehicle body crash simulation method was calibrated and revised based on static pressure of roof,frontal impact test and rear impact *** this basis,a systematic crash simulation method of carbon fiber vehicle is established,which ensures the high consistency between simulation results and vehicle level test,and has guiding significance for carbon fiber vehicle body design.
