摘　　要：基于NF100偏心圆弧线型面楔块逆止器的基本结构参数,设计一种非接触式对数螺旋线型面楔块逆止器。应用SolidWorks对其非接触过程运动状态进行分析,研究表明可实现非接触运动。应用Ansys/LS-DYNA对其逆止过程进行动态仿真,得到了楔块的受力变化规律,并将所得结果与NF100偏心圆弧线型面楔块逆止器的仿真结果进行对比,研究表明对数螺旋线型面各楔块的受力更小且更加均匀,逆止过程更加平稳。A non-contact logarithm spiral surface wedge block backstop is designed based on the basic structural parameters of NF100 eccentric circle surface wedge block backstop. SolidWorks is used to analyze its motion state during non-contact process. Studies show that non-contact motion is no problem. ANSYS/LS-DYNA is used for dynamic simulation of its backstop process, obtaining the load changing law of wedge blocks. Tile results are compared with the simulation results of eccentric circle surface wedge block backstop, showing that logarithm spiral surface wedge blocks bear less and more even loads and have smoother backstop process.
