| Abstract: | The research of the occupant's kinematic response during collision is the basis of protecting occupant's safety in an accident' The influence on occupant's kinematic response due to the stiffness of the belt and the position 0f the belt's top-fixed point are studied in this paper by using the advanced computer sAnulation, the program MADYMO and the theory of regression as an organic whole. The results reveal the variable Tegularity of Head Injury Criterion (HIC) affected by linear and nonlinear interaction of every parameter. According to the results we can obtain the optimum regressive equations and provide the scientific basis for the correct selection of the stiffness of belts and the correct construction of the position of belt's top-fixed point. |
