Abstract: This paper mainly uses nonlinear finite element software ANSYS/LS-DYNA to simulate the impact response of the sandwiched polyurethane composite steel tube as well as the traditional steel pipe. Comparative numerical simulation experiments were carried out in which sandwiched polyurethane tube and steel tube with the same mass were respectively collided with rigid balls in the same velocity. The paper mainly analyzes the maximum collision force, absorbing energy and the maximum collision depth of the rigid collision ball of the two different types of tube. Then it concludes that the sandwiched polyurethane composite pipe crashworthiness of the collision is better than that of the traditional steel tube.
