FRICTIONAL FORCE MEASUREMENT METHOD AND FRICTIONAL FORCE MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a frictional force measurement method and a frictional force measuring device capable of more accurately measuring the static frictional force, maximum static frictional force and dynamic frictional force.;SOLUTION: The frictional force measuring method for measuring frictional force between a roller 10 and paper 20 in a mutual contact state by moving the paper 20 at constant speed, while keeping the contact state in the fixed state of the roller 10, is such that frictional force between the roller 10 and paper 20 is measured continuously, while moving the paper 20 and that the movement of a local part (a tracer) near a portion, brought into contact with the paper of the roller 10 at a point of time before moving the paper 20, is monitored throughout the movement of the paper 20 so that static frictional force and dynamic frictional force are measured.;COPYRIGHT: (C)2009,JPO&INPIT
