차량 도어 래치의 작동력 계산을 위한 수식 유도 :파트 2-OS/IS래버, 전체 작동력 분석

초록

A car door has an inner handle and an outer handle. The magnitude of the operating force of the two handles is commonly influenced by the catch, pawl, and release lever of the door latch, and is divided into an OS lever and an IS lever. OS lever and IS lever are connected to the cable of the handle allowing the final operating force to be obtained. Therefore, it should be divided into two cases in the release lever in the door latch. Because the formulated variables change, an analysis of how much each variable contributes to the maximum operating force needs to be undertaken. In particular, because each part has a torsion spring attached, which part contributes the most to the maximum operating force owing to a change in the spring coefficient should be analyzed. In addition, since the maximum operating force is expressed as the force on the moment, the maximum operating force according to the change of distance from the center of rotation to the contact point between parts is analyzed.
