ABSTRACT
Objective To explore an method for comfort evaluation of the military ambulance to enhance ride comfort during casualty transport. Methods The method executed quantitative evaluation of vibrational comfort by the existing vibration comfortableness evaluation ways for non-ambulatory casualty, different reactions of casualty to vibrational excitement and annoyance rate analysis based on psychophysics, which took considerations on the ratio of injured sites at war or natural disaster conditions as well as susceptibility analysis. Trials of the the method were carried out on the vibrational comfort analysis of some military ambulance during the road test.Results The method had feasibility for vibration comfortableness evaluation of non-ambulatory casualty,and improved the traditional ways in quantitative analysis.Conclusion The method gains advantages over the international ways, and contributes to the related researches on vibration reduction.
