Development of Treadmill for Sprague-Dawley Rats Training with Dynamic Body Weight Support System
Since the current rat body weight support training experimental treadmill mostly adopts the body weight support(BWS)model with one end of the spring fixed,the fluctuation of the gravity center of rats under the weight support mode would cause peri-odic changes of the spring force,which would cause secondary damage to rats.Therefore,a kind of dynamic body weight support mode in which both ends of the spring can be freely stretched had been proposed,which could guarantee the weight loss fluctuated within a very small range and provide an advanced experimental platform for the development of rats walking training experi-ments.Firstly,Solidworks software had been used to build the 3D model of the treadmill,and ANSYS software had been used to perform static analysis on the main components of the treadmill to verify the stability of the structure of the treadmill.Secondly,the PID control algorithm of dynamic body weight support control system had been used to obtain the body weight values and ad-just the elongation of the spring in the training process in real time,to reduce the fluctuation of system weight loss values,and the treadmill control system had been used to adjust and collect the speed of the running belt.Finally,the effectiveness of the treadmill had been verified by the experiments of walking training in Sprague-Dawley Rats.
