车辆振动和乘客不适的测量已用于评估预测乘客振动不适的替代方法。考虑了对身体的十二个振动输入：座椅上的三个平移轴和三个旋转轴、背部的三个平移轴和脚部的三个平移轴。通过对八名男性受试者的所有十二个输入进行实验室实验获得了等效的舒适轮廓。然后将这些受试者对在十二条不同道路上乘坐六辆不同汽车的反应与平均十二种振动输入的九种替代方法相关联。仅对“最差”振动输入或“最差”振动频率进行评估并不能提供良好的预测。应确定频率和轴加权加速度的 rms 或 rmq。这十二个值的平方和的平方根提供了与车辆不适等级的最佳相关性。
Measurements of vehicle vibration and passenger discomfort have been used to evaluate alternative methods of predicting passenger vibration discomfort. Twelve vibration inputs to the body were considered: three translational and three rotational axes on the seat, three translational axes at the back and three translational axes at the feet. Equivalent comfort contours were obtained by laboratory experimentation for all twelve inputs for eight male subjects. The responses of these subjects to the ride in six different cars on twelve different roads were then correlated with nine alternative methods of averaging the twelve vibration inputs. Evaluation on only the "worst" vibration input or the "worst" vibration frequency did not provide good predictions. Either the rms or rmq of the frequency and axis weighted accelerations should be determined. The square root of the sums of squares of these twelve values provided the best correlation with the discomfort ratings in the vehicles.
