摘　　要：介绍了表面纳米化设备的应用前景和工作原理以及设备中叶轮机构的设计与分析过程。通过不同方案之间的对比分析最终确定叶轮机构的方案,然后对叶轮中弹丸的运动进行理论分析。通过三维建模软件Pro/E建立起弹丸在叶轮机构中运动的三维模型,模型导入到仿真软件ADAMS中,在ADAMS中对各种参数设定后进行运动学和动力学的仿真分析,仿真结束后进入Post Processor界面,得到弹丸速度、加速度、受力图,这有助于确定弹丸甩出的位置,以保证高速弹丸准确的击打在工件上,同时对叶轮进行受力分析,为叶轮模型的优化提供依据。This paper briefly introduces the application prospect and working principles of the equipment for surface nanocrystalliza- tion as well as the design and analysis process of its impeller and after a contrast analysis of three different impeller structure solutions, confirms the best one, and then makes a theoretical analysis of the projectile＇ s motion of the impeller. Via three dimensional （3D） modeling software Pro/E, it also establishes the projectile movement 3D model, which is imported into simulation software ADSMS and after setting various parameters in ADAMS, makes the simulation analysis of the projectile＇ s kinematics and dynamics then gets the velocity, acceleration velocity and force diagram in the PostProcessor interface. It is useful to confirm the tossed out location of the projectile and to ensure high-speed projectile to accurately striking on the workpieces, at the same time, a stress analysis on the impeller is done. The basis is provided for the optimization of the impeller model.
