The CST design method of matching both European and American crash regulations

To satisfy Collision safety requirements formuled by both FMVSS208 and ECE R94 for vehicles fixing CST, take metro as the research object, which mass is 0.8 tons, using universal principles of particle kinematics and dynamics, and obtain the CST-ideal energy absorption curve which can satisfy both FMVSS208 and ECE R94. To make sure that the designed CST can obtain ideal energy absorption curve, having optimized the practical structure and optimal parameters by orthogonal optimization, based on VPG and LS-DYNA software platform.
