急救车卧位人体振动的计算机模拟与试验分析

The computer simulation and experimental analysis of ambulance-supine body system's vibration

描述了路面随机输入下的急救车卧位人体振动数学模型的建立,复合频率响应函数的推导,响应谱的计算。模拟计算和试验进行了对比分析,结果比较吻合。此方法对分析和预测卫生技术车辆的平顺性有一定的典型性。

An math modeling of ambulance-suspine body system's vibration to random road input has been established. By using this math modeling, the complex frequency response function is obtained, andthe response power spectrums are worked out. The computer simulation results and the experimental results are compared and analysed. The two results quite correspond. This method is typical for analysing and forecasting the riding comfort of medical vehicles.
