摘　　要：目的:研究、设计并制作一台教学使用的仿真工频X线机,解决教学过程中实验设备费用高、数量不足、机器占地面积大等缺点。方法:以经典F78-Ⅲ型X线机电路图作为仿真机电路设计蓝本,在满足教学要求的前提下对原型机功能和电路进行简化,对部分电路重新设计,元件采用平铺式裸露安装,方便学生观察元件的工作情况。结果:制作完成后的仿真X线机能够很好地仿真实际X线机的工作过程,教师可以借助仿真机对学生进行X线机基本工作原理的演示。结论:解决了教学设备不足的问题,并对设计其他仿真教学仪器有一定的借鉴意义。Objective A simulation power frequency X-ray machine for teaching was developed in the paper to solve the disadvantage of high cost, inadequate quantity and huge bulk of experimental equipment. Methods The circuit of traditional F78-Ⅲ X-ray machine was taken as the blueprint for simulation circuit design. The function and circuit of prototype machine were simplified on the premise of meeting teaching needs. Some circuits were redesigned. All the components were exposed and mounted on a flat plate to facilitate students to observe the real-time working condition of components. Results The developed simulation machine perfectly simulated the working condition of actual X-ray machine. And the simulation machine was applied by teachers to demonstrate the basic working principle of X-ray machine for students. Conclusion The simulation machine solves the problem of equipment shortage, with some certain reference value for designing other simulation teaching equipments.
