Abstract:

First， the Hybird III dummy and CHUBM human were used to build 50 km/h frontal 100% rigid barrier virtual collision simulation platform to conduct preliminary exploratory study. Then，three finite element models of the vehicle collision were established under the Hybird III dummy seat position A and CHUBM human seat position A and B. And three cases under the driver's head， chest and thigh injuries were compared by analysis in simulation. The results showed that Hybird III dummy of seat position A and CHUBM human of seat position B had a good consistency in the dynamic response. The head and chest injuries of CHUBM human under different seat positions were higher than Hybird III dummy. The injury indicators of CHUBM human at seat position A were higher than that at seat position B， and the fracture of human ribs was occurred. The research results show that the CHUBM human has more realistic human anatomy and bionic fidelity， and has higher requirements for the safety evaluation of vehicle restraint systems， which can provide corresponding reference for the safety protection design of vehicle.

Key words: vehicle engineering, CHUBM human model, Hybird III dummy model, vehicle collision, injury comparison
