SLIP RESISTANCE MEASURING DEVICE
To provide a slip resistance measuring device that can measure a static friction coefficient while moving.SOLUTION: The device includes a first roller 11 placed on the road surface, a base for supporting the first roller 11, moving means 18 for pressing the base 20, an arm portion 13 that is swingably supported at the base, a second roller 14 placed on the road surface rotatably supported in the arm portion 13, a winding spring 21 tightened when the second roller 14 rotates, a one-way clutch 30 to limit the movement of the second roller 14 in one direction, a turning sensor 90 for detecting a magnitude of the movement of the second roller 14 to generate a turning signal, maximum value detecting means 25 for detecting the maximum value of the turning signal, and static friction coefficient calculating means 90 for calculating a static friction coefficient from the static force applied to the second roller 14 calculated from the maximum value and a weight applied to the second roller 14.SELECTED DRAWING: Figure 1
【課題】動きながら静摩擦係数が測定可能なすべり抵抗測定装置を提供すること。【解決手段】路面上に載置される第１ローラー１１と、第１ローラー１１を支持する基部と、基部２０を押す移動手段１８と、基部に揺動自在に支持されるアーム部１３と、アーム部１３に回動自在に支持され路面上に載置される第２ローラー１４と、第２ローラー１４が回転すると締る巻きバネ２１と、第２ローラー１４の回動を一方向に制限するワンウェイクラッチ３０と、第２ローラー１４の回動の大きさを検出して回動信号を発生する回動センサ９０と、回動信号の極大値を検出する極大値検出手段２５と、極大値から算出される第２ローラー１４に加わる静摩擦力と、第２ローラー１４に加わる重さとから静摩擦係数を算出する静摩擦係数算出手段９０とを有する。【選択図】図１
