针对分离脱落电连接器钢珠锁紧机构解锁可靠性问题,通过分析其解锁原理,建立了钢珠锁紧机构解锁过程的力学模型,进而得到了机构解锁临界点的解锁阻力,并对锁紧钢珠的自锁情况进行了分析,得到了机构自锁的条件。通过分析影响机构解锁阻力的各个参数的分布情况并利用蒙特卡洛分析方法,得到了机构解锁阻力的概率分布和机构自锁角的概率分布,并对该分布进行检验,然后利用极大似然估计法得到各自的均值和方差,最后根据该型产品机械解锁力的允许范围以及机构在解锁临界点的可靠度和机构不发生自锁的可靠度,并利用串联可靠性模型得到钢珠锁紧机构解锁的可靠度。结果表明,该方法能够有效地分析钢珠锁紧机构的解锁可靠性,并为其可靠性设计提供参考。
Aiming at the problem of the reliability of the unlocking of the steel ball locking mechanism of the detached electrical connector, the mechanical model of the locking process of the steel ball locking mechanism is established by analyzing its principle of unlocking, then the unblocking resistance of the mechanism unlocking critical point is obtained, Self-locking situation was analyzed, the agency has been self-locking conditions. By analyzing the distribution of each parameter affecting the unblocking resistance of the mechanism and using the Monte Carlo analysis method, the probability distribution of the mechanism unblocking resistance and the self-locking angle of the mechanism are obtained, and then the distribution is tested. Then the maximum likelihood Finally, according to the allowable range of the mechanical unlocking force, the reliability of the mechanism at the unlocking critical point and the reliability of the mechanism without self-locking, and using the series reliability model, the ball locking mechanism Unlock reliability. The results show that this method can effectively analyze the reliability of the locking mechanism of the steel ball and provide a reference for its reliability design.
