| Abstract: | 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 PQLD′s 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. |
