摘要
载人航天器舱门快速检漏仪是载人航天器舱门及其对接机构对接面气密性检测的测试仪器。为了验证舱门快速检漏仪的可靠性指标水平,按照寿命型和计量型可靠性试验方法的基本思路,通过分析其功能、工作原理和主要故障模式,确定了可靠性特征量,提出了舱门快速检漏仪的可靠性验证试验方法,包括试验方法的选择、试验件状态、试验条件的确定、试验程序、故障判据及可靠性评估方法,并给出了评估结果。
As the port and its docking system testing instrument, manned spacecraft port quick leak detector （PQLD） is used for checking the sealing quality of the docking surface after the door is closed and the docking surface is linked. By analyzing the function, the work principle and main failure mode of PQLD for manned spacecraft was presented, and the PQLDIs reliability characteristic was determined. According to the basic considerations of life-type and computation-type reliability test method, the methods of the PQLD reliability test was proposed, including the choice of the method, statement of the test piece, determination of the test condition, test program, failure criterion , and means of the reliability evaluating.
