摘　　要：论述了载人飞船某连接分离机构的功能、工作原理和主要故障模式,确定了该连接分离机构的可靠性特征量。基于计量型可靠性试验的基本思路,提出了该连接分离机构的可靠性试验方法,包括试验方法选择、试验件状态及试验条件的确定、试验程序、故障判据和可靠性评估方法;给出了应用示例,为载人飞船连接分离机构的可靠性验证提供了技术参考途径。The functions, principles and failure modes of a connecting/separating mechanism for manned spacecraft were introduced. Reliability characteristic parameters of the mechanism were given. The reliability Verification test method of the mechanism was put forward, including test method choosing, test state determination, test program, failure criterion and reliability assessment method. An application example of the method was shown. By these reliability verification test methods, the reliability of the connecting/separating mechanism for manned spacecraft could be verified.
