MA Zhi-xin

Open publisher page 2 citations

Abstract

Flexible hinges have the peculiarities of non-clearance, frictionless and high sensitivity, and is usually designed to be used and acted as a displacement amplifier. On the basis of carrying out the stress analysis and displacement loss analysis on the flexible hinges, the influences on the magnification capacity of flexible hinge affected by the allowable maximum input displacement and loading of the displacement magnification mechanism were studied. The relation between loading and magnification multiplying factor was analyzed and the mathematical model of displacement magnification was established.
