Study on Effect of Rolling Crashworthiness of the Main SUV Vehicle Components
Aimed at the body of SUV vehicle , according to the criteria of FMVSS216 vehicle safety regulations , in LS-DYNA software environment , the simulation analysis of effects of the design parameters of main components of the body on roll crashworthiness in the process of vehicle crashing and rolling is presented in the paper , based on finite element analysis method, with the test methods of applying pendulum collision. The characteristics of the crashworthiness and energy absorption of the pillar pendulum which have different design parameters, such as shapes and thickness, et. al., are emphasized particularly in the paper. A simple finite element model of SUV is established, the effect of different design parameters of stiffness of body cover to the whole distribution of energy absorption and the reasonable transfer of total energy is discussed. The noticeable issue and advice on body design of SUV is proposed.
