Abstract

Difference thresholds of whole-body vibration is important to determine perceptibility of changes in vehicle vibration and can be used to guide ride comfort improvements. It is postulated that estimated difference thresholds in a laboratory setting should be applicable to real-world driving conditions given that the stimuli are similar. This study considers the aspect of vehicle vibration associated with the stimulus. A validated non-linear SUV vehicle model is simulated on a 4-poster test rig and driven in a straight-line over a rough road. This allows for the vehicle vibration to be compared between vertical excitation only (4-poster) and complete excitation (straight-line driving) by the road profile at each of the four wheels. Results show that differences in the seat vibration exists between the 4-poster test rig and straight-line driving simulations. These differences are larger than difference thresholds implying that they would most probably be perceivable. Further investigations are needed to determine the influence of differences in vibration stimuli on difference thresholds.

使用差异阈值对 4 柱式驾驶模拟和整车驾驶模拟的乘坐舒适性进行比较
全身振动的差异阈值对于确定车辆振动变化的可感知性非常重要,可用于指导驾驶舒适性的改善。据推测,实验室环境中估计的差异阈值应适用于真实世界的驾驶条件,因为刺激是相似的。本研究考虑了与刺激相关的车辆振动方面。在一个 4 柱测试平台上模拟了一个经过验证的非线性 SUV 汽车模型,并在崎岖道路上直线行驶。这样就可以比较四个车轮上的路面轮廓对车辆振动的垂直激励(4 柱式)和完全激励(直线行驶)。结果表明,4 柱式试验台和直线行驶模拟的座椅振动存在差异。这些差异大于差异阈值,这意味着它们很可能是可感知的。要确定振动刺激差异对差异阈值的影响,还需要进一步调查。
