将仿生气动人工肌肉(PAM)运用于急救车车载担架隔振平台，作为担架的缓冲执行机构，建立缓冲减振系统数学模型，以白噪声模拟路面输入，运用Simulink结合模糊PID控制理论进行仿真。在选定的3种工况下，分析担架在主动控制与被动情况下振动的垂向加速度和俯仰角加速度。结果表明PAM仿生担架隔振平台可有效减小担架所受到的振动冲击，提高病人的乘卧舒适度。研究结果可为急救车担架的设计提供一定的参考。

As a bionic buffer actuator, pneumatic artificial muscle (PAM) is used for a vibration isolation platform of a stretcher mounted in an ambulance. 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 research results may provide some references for the design of ambulance stretchers.
