Dynamic friction coefficient measurement apparatus and method

摘要

PROBLEM TO BE SOLVED: To provide a device for measuring a dynamic friction coefficient by pulling a linear object at an actual traction speed or a pulling-out speed.;SOLUTION: This dynamic friction coefficient measuring device is equipped with: a linear object fixing means for fixing one end of the linear object, a movable stand movable on an installation surface; a loading means applying a load to the linear object; a traction means for pulling the movable stand with constant traction force to a direction opposite from the linear object fixing means by a prescribed distance; a stop time measuring means for measuring stop time until the movable stand stops after pulling the movable stand to the prescribed distance; and a dynamic friction coefficient calculating means for calculating a dynamic friction coefficient of the linear object from mounting stop time which is the stop time until the movable stand stops after pulling the movable stand to the prescribed distance, and a dynamic friction coefficient between the movable stand and the installation surface when the linear object is not mounted.;COPYRIGHT: (C)2011,JPO&INPIT
