Embodiment Construction
[0020] The method for reliability verification of an underwater vehicle based on the Bayes method in this embodiment is a method proposed for the mass production and manufacture of an underwater vehicle based on the reliability verification work of the actual voyage work in the production finalization stage. In the prior art, the following two methods are often adopted: First, a classical scheme is adopted, and a test scheme is selected according to the reliability index and confidence of the actual flight operation. The classical method is to formulate a verification and evaluation scheme for the reliability of underwater vehicle operation in actual operation without considering the reliability information in the design and finalization stage. big. Considering the non-recyclability of underwater vehicle carriers and the fact that the first batch of small batches is often produced in small quantities at present, it will be difficult to ensure the test volume of underwater vehi...

The invention discloses an underwater vehicle reliability verification method based on a Bayes method. Comprising the steps of design shaping prior information structure analysis and prior information determination, production shaping quality control factor analysis and prior information determination, production shaping actual aviation work reliability prior distribution determination, posterior distribution determination, risk analysis, verification test scheme formulation and the like. The Bayes method is practically verified through engineering application in reliability verification and evaluation of design and shaping of the underwater vehicle and reliability verification and evaluation of other equipment such as the underwater vehicle, and has good inheritance and feasibility in application in production and shaping.
Description
technical field [0001] The invention relates to the technical field of reliability verification of underwater vehicles, in particular to a method for reliability verification of underwater vehicles based on the Bayes method. Background technique [0002] From the development stage to the production finalization stage to the batch production stage, the reliability level of the underwater vehicle generally follows the following rules: in the development stage of the underwater vehicle, with the gradual advancement of the principle prototype, the initial prototype to the positive prototype, the underwater navigation After continuous testing, analysis and improvement, the reliability of the device design defects, manufacturing process defects, parts selection and operation method defects is gradually improved. This stage is an important part of reliability growth. In the design and finalization stage, through the reliability appraisal test, comprehensive inspection of the design...
