Abstract: 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.
