| Abstract: | The paper describes how the 3D solid model of NYD type backstop is built by means of Pro/Engineer,and how the back-stop functioning process simulation with the different eccentricities and radius peculiar shape blocks is analyzed by means of ANSYS/LS-DYNA software. It derives the influence of dimension parameter of peculiar shape block to the backstop performance,offering a reference for design and improvement of the backstop's peculiar shape block. |
