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 function, working principle and main failure modes of a connecting and disconnecting mechanism of a manned spacecraft are discussed. The reliability characteristics of the connecting and disconnecting mechanism are determined. Based on the basic idea of metrological reliability test, the reliability test method of the connecting and disconnecting mechanism is proposed, including the selection of test methods, the state of test pieces and the determination of test conditions, the test procedures, the fault criteria and the reliability assessment method. The application example provides a technical reference for the reliability verification of the manned spacecraft attachment and detachment mechanism.
