Human engineering Examination of Rear-hinge Door Operation

摘要

To achieve the operational performance improvement of the rear-hinge door, a human engineering examination with manipulability ellipsoid forecast technique (manipulating force ellipsoid) that clarify mechanical characteristic of the arm is applied. The idea of (he operational performance improvement (muscular load decrease) is clarified considering "Easiness of power to demonstrate" by analyzing feature of human operation from the viewpoint of the direction of the demonstrating power and muscular load.
