차량 도어 래치의 작동력 계산을 위한 수식 유도 :파트 1- 캐치, 파울 및 릴리스 래버

초록

Numerous studies on improving the emotional quality and automatic functionality of automobiles have recently been conducted based on various aspects. The first components touched by passengers are the vehicle doors, and thus the feeling of the opening and closing of the doors is a significant emotional quality and should be treated seriously. In this regard, mathematical equations calculating the operating force of the door latch, which have yet to be reported elsewhere, are formulated in this study. The forces acting on each component are gravity, elasticity, friction, and the normal force. Therefore, the door latch operating force has been formulated as the moment of the force action because all parts rotate about the axis of rotation. Because there are numerous parts used in a door latch, this study is divided into two parts. In part 1, formulas used to calculate the operating force of the catch, pawl, and release lever are determined. And formulas for calculating the OS levers, IS levers and the maximum operating force are analyzed in part 2. In addition, a clear definition of the opening point and the operating force up to the release lever is formulated.
