Analysis of Hysteresis Characteristics for Positioning Mechanism. Evaluation of Influences with No-Backlash Gearing.

open access: yesJournal of the Japan Society for Precision Engineering, 1993
It is very difficult to eliminate the mechanical hysteresis for positioning lnechanism. Weneed the allowable mechanical hysteresis magnitude, when we improve the mechanism performance.So that it has been proposed the evaluation methods of mechanical hysteresis influences on dynamic performance using the mechanical hysteresis test unit.
