起落架指型锁解锁力特性的研究
Research on Unlocking Force Characteristics of Landing Gear Finger Lock
摘要
Abstract
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.关键词
