摘　　要：应用Pro/Engineer软件建立了NYD型逆止器的三维实体模型,并应用显式动力学弹塑性有限元ANSYS/LS-DYNA软件对具有不同偏心距和圆弧半径的异形块的逆止过程进行数值模拟分析,研究异形块工作面尺寸参数对逆止器逆止性能的影响。研究结果对逆止器异形块的设计和改进具有一定的参考价值。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.
