| Abstract: | An effective structure of deformation inducing groove was proposed by analyzing a variety of deformation-inducing structural features.The groove structure was used in front rail of a vehicle's frame for collision simulation to improve its dynamic crashworthiness characteristics of energy absorption.Several design parameters of the front rail structure were selected and used to optimize the structure.The analytic methodology adopted in this research combined response surface method(RSM) with orthogonal exper... |
