To provide an analyzer capable of analyzing the behavior of debris that is kicked up from the road surface by the tires of a moving vehicle.SOLUTION: An analyzer includes a debris behavior estimation unit that estimates the movement direction and the movement force Fmix of debris blown by the tires on the basis of a ground angle, which is the angle between a vertical line passing through the center of rotation of a tire 35 of a vehicle traveling on a road surface Rs and a line connecting the center of rotation and a point on the outer surface of the tire where the tire begins to move away from the road surface and the debris size Sd, which represents the size of debris Sd located on the road surface.SELECTED DRAWING: Figure 9
【課題】走行中の車両のタイヤによって路面から跳ね上げられた砕屑物の挙動を解析可能な解析装置を提供する。【解決手段】路面Rs上を走行中の車両のタイヤ35の回転中心を通る鉛直線と、タイヤの外周面における路面から離れ始める位置と回転中心とを結ぶ直線と、がなす角度である接地角、及び、路面上に位置する砕屑物Sdの大きさを表す砕屑物寸法に基づいて、タイヤによって飛ばされた砕屑物の移動方向及び移動力Fmixを推定する砕屑物挙動推定部を備える。【選択図】図9
