为合理地分析、评价救护车卧姿乘员的受振舒适性，进行了卧姿人体全身振动暴露的舒适性实验研究。通过１３名志愿受试者三百多人次的实验，得到了卧姿人体全身振动暴露１ｍｉｎ降低舒适性的阈限，并据此导出了１６ｍｉｎ、２５ｍｉｎ、１ｈ、２．５ｈ、４ｈ、８ｈ、１６ｈ、２４ｈ对应的降低舒适性界限；建立了相应的舒适性评价方法，将其应用于某野战急救车的乘卧舒适性评价，取得了较好的效果。
In order to reasonably analyze and evaluate the vibration comfort of the occupant in the prone position of an ambulance, the comfort experiment of human body vibration in a prone position is carried out. Through the experiment of more than 300 volunteers from 13 volunteers, the threshold of total body vibration exposure for 1min to reduce comfort was obtained. Based on this, the thresholds of 16min, 25min, 1h, 2.5h, 4h, 8h, 16h , 24h corresponding reduction of comfort boundaries; established a corresponding comfort evaluation method, which applied to a field ambulance riding comfort evaluation, and achieved good results.
