救护车担架系统振动的阻尼主动控制研究

Study on Active Vibration Control for Ambulance Stretcher System Based on Sky Hook Damper Theory

提出了救护车担架主动控制隔振系统的概念，并引用惯性阻尼原理研究了救护车担架－卧位人体系统振动的主动控制问题。仿真结果表明，担架主动控制隔振系统能有效地降低担架－卧位人体系统垂直振动和纵向角振动的加速度均方根值，从而在改善救护车担架平顺性方面具有重要的应用价值。

In this paper, a new conception——active vibration isolation system of ambulance stretcher is put forward and the design of active vibration control system for ambulance stretcher based on Sky Hook damper theory is presented. The results of numerical simulation show that the proposed active vibration isolation system may reduce the vertical and pitch accelerations of stretcher supine body system significantly, so it has great practical value in improving the ride quality of ambulance stretcher.
