| Abstract: | Both the vehicle and the concrete barrier are regarded as rigid bodies. An impact equation represented by pesudo-velocities(velocity of vehicle centroid and angular velocity of vehicle) is derived from Appell equation. Under some simplified conditions, a semi-analytical method based on the impact equation is obtained, which can figure out the maximum average accelerations; the maximum roll angle and the exit angle, which can be used to evaluate the safety performance of concrete barrier comprehensively. |
