摘　　要：为了检验转向轴的质量,设计了转向轴扭转疲劳试验台。介绍了试验台的机械结构,设计了以PIC芯片为控制器的硬件电路,阐述了软件的编制流程。该试验台可以保证加载的扭矩恒定,方便地显示加载次数。系统自动化程度高,运行稳定可靠。In order to verify the quality of the steering shaft,a test stand is designed for the purpose of torsional fatigue test. In this paper the mechanical contracture is introduced,the hardware circuit based on PIC microcontroller is designed and the flowchart of the control software is drawn. The test stand can ensure constant torque load and display the experimental times conveniently. The system has high automotive degree and works stably and reliably,which shows that the design of the test stand is successful.
