Damping model of the stretcher is built up, and the white noise is employed to simulate the pavement input. Simulation of the stretcher is conducted using simulation software Simulink and fuzzy PID control. The vertical acceleration and pitch angle acceleration are analyzed for the PAM stretcher and the traditional stretcher respectively in 3 working conditions. The simulation results show that the PAM stretcher can effectively reduce vibration impact to the stretcher and improve the comfort of patients. The r
