Unlocking reliability analysis of the ball locking mechanism for separating electrical connector
摘要
Abstract
Aiming at the unlocking reliability of the ball locking mechanism for separating electrical connector ,the mechanical model for the mechanism unlocking process is established by the analy-sis of the unlocking principle .The unlocking resistance of the critical point of the mechanism was obtained ,and the self-locking conditions for the mechanism were acquired by analyzing the self-locking situation of the locking ball .Based on the analysis of the distribution of various parame-ters affecting the unlocking resistance for the mechanism ,the probability distribution of the loc-king resistance and the self-locking angle were attained by Monte Carlo method ,then the two dis-tributions were tested .The means and variances of the two distributions were calculated by maxi-mum likelihood estimation method .Finally ,according to the allowable range of mechanical un-locking force ,the unlocking reliability at the critical point and the reliability of non-self-locking were obtained respectively ,and the unlocking reliability for the mechanism was evaluated by se-ries reliability model .The results show that the proposed method is effective for the analysis of the ball locking mechanism unlocking reliability and it provides a reference criterion for the mech-anism reliability design .关键词
