Research on Unlocking Force Characteristics of Landing Gear Finger Lock
研究了指型锁的长度、直径和指尖角度等因素对解锁力的影响,获得了解锁力的理论计算公式并分析了影响解锁力的敏感参数.首先对指型锁解锁力进行理论计算,获得解锁力与各个参数改变的变化规律;然后通过实验验证模型的有效性;最后使用正交实验法分析了各参数对解锁力影响的敏感性.结果表明,本文所得计算公式有效可靠;指型锁长度、直径1、直径2与解锁力负相关,指尖角度与解锁力正相关;影响解锁力的参数敏感性由高到低分别为指型锁长度、直径1、指尖角度和直径2.
The influence of the length,diameter and fingertip angle of the finger lock on the unlocking force is studied,the theoretical calculation formula of the unlocking force is obtained,and the sensitivity of parameters to the unlocking force is analyzed.Firstly,the change law of the unlocking force is obtained by theoretical calculation.Then,the validity of the model is verified by experiments.Finally,the sensitivity of each parameter to the unlocking force is analyzed by orthogonal experiment.The result shows that the theoretical calculation formula is effective and reliable,the length,diameter 1 and diameter 2 of the finger lock are negatively correlated with the unlocking force,while the fingertip angle is positively correlated with the unlocking force;and the sensitivity of parameters affecting the unlocking force from high to low is finger lock length,diameter 1,fingertip angle and diameter 2.
