救护车卧姿乘员受振舒适性的评价研究

为合理地分析和评价救护车卧姿乘员的受振舒适性，开展了卧姿人体全身振动暴露的舒适性试验研究。通过对１３名志愿受试者３００多人次的试验，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和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卧姿舒适性评价，取得了较好的效果。

Comfort Evaluation for Ambulance Passenger Sustaining Vibration in Lying Posture

Experimental research of comfort has been carried out for full man body sustaining vibration in lying posture in order to rationally analyse and evaluate the comfort quality for ambu-lance passenger sustaining vibration in lying posture. After more than 300 man-times experiments for thirteen volunteer testers,the threshold limit value of comfort reduction field for full man body in lying posture sustaining lmin vibration is obtained,which has been based upon to derive out the limit of comfort reduction corresponding to 16 min, 25 min, 1h, 2. 5h, 4h, 8h, 16h and 24h. Method of comfort quality evaluation is then established and applied to the comfort evaluation of a certain ambulance for field operation,which achieves better results.
