Diffuse axonal injury (DAI), which is the most important types of brain injury, is the main cause of death, serious disability and vegetative being. In order to study the DAI, a experimental device with high stability and good reproducibility was designed, which can simulate the clinical process of the DAI injury. This paper described the design process in detail, such as the choosing of the driving force, the design of the linked structure, the design of limited block and the choice of sensors. Finally, the verification of feasibility and superiority of the device by rat experiments was done.
