DEVICE AND METHOD FOR TESTING FRICTION

To precisely detect the frictional characteristics including the coefficient of friction between two samples in contact with each other at their surfaces.SOLUTION: The device for testing friction includes: a first holder capable of holding a first sample; a second holder capable of holding a second sample when the second sample is being in contact with a surface of the first sample; weight application means for applying a weight to the second holder in a direction perpendicular to the contact surface where the first sample and the second sample are in contact with each other; sliding means for sliding the second sample with respect to the first sample along the contact surface by making an external force act on the second holder on the extension of the contact surface; and frictional force detection means for detecting a frictional force which acts on the first holder by sliding of the second sample.SELECTED DRAWING: Figure 1 【課題】面接触状態の二つの試料間の摩擦係数等の摩擦特性を正確に検出する。【解決手段】第１試料を保持可能な第１ホルダと、第１試料に面接触させた状態の第２試料を保持可能な第２ホルダと、第２ホルダに対して第１試料と第２試料との接触面に垂直な方向に荷重を負荷する荷重負荷手段と、第２ホルダに接触面の延長上で外力を作用させることにより、第２試料を第１試料に対して接触面に沿って摺動させる摺動手段と、第２試料の摺動により第１ホルダに作用する摩擦力を検出する摩擦力検出手段と、を備える。【選択図】 図１
