【Abstract】 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.更多还原
