Paper Title:
Combinational Methods of Vehicle Frontal Crashworthiness Optimization Based on Conceptual Model
  Abstract

Through full factor analysis of the stiffness of the components which have potential influence on vehicle front impacts, through sensitivity analysis of vehicle front impacts using Linear Regression Method, the stiffness significantly affected the impacts are chosen as the optimization variables. The vehicle intrusion and the deceleration waveform of B pillar are weighted as the optimization objective. The Latin Hypercube Sampling Method is used to do sampling; a response surface of the calculation results is established using Kriging Method; the optimization is done using Method of Feasible Direction, finally the most optimal car body stiffness is determined, and which can provide the basis for frontal crash safety design of the electric vehicle.
