Embodiment Construction

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The embodiment of the present invention provides a reliability test method for naval electromechanical equipment that can be carried out in a laboratory. As the electromechanical equipment of a ship, take a certain type of electromechanical equipment for a ship as an example. Its main function is to give an alarm when the ship encounters a dangerous situation, and release a beacon to indicate the rescue position. The reliability index MTBF is 100 hours, a...

Abstract

The invention discloses a naval vessel electromechanical equipment reliability test method, which comprises the steps of determining the composition of a test profile capable of covering a mission profile according to the mission profile of naval vessel electromechanical equipment, the test profile comprising an in-box test profile and an out-box test profile; determining the environmental stressof the naval vessel electromechanical equipment and the stress condition of each environmental stress; according to the reliability index of the electromechanical equipment, determining the cycle index of the in-box test section and the empirical coefficient of the out-box test section; performing an in-box test according to the in-box test profile and the cycle index; performing an out-of-box test according to the out-of-box test profile and the empirical coefficient; and judging whether the electromechanical equipment of the naval vessel reaches a reliability index or not according to a testresult. The reliability test method for the electromechanical equipment of the naval vessel can be carried out in a laboratory, and the reliability index of the electromechanical equipment of the naval vessel can be assessed.

Description

technical field [0001] The invention belongs to the technical field of reliability testing, and in particular relates to a reliability testing method for electromechanical equipment of ships. Background technique [0002] There are many types of electromechanical equipment in naval equipment, and their reliability also has high requirements, and is related to the reliability level of the entire naval equipment system. Ship electromechanical equipment includes mechanical components and electronic components, which are complex in composition and interact with each other. At present, the assessment of its reliability is mostly carried out with the field test of the complete equipment. The test cost is high, the test cycle is long, and the timing of finding problems is late, which affects the progress of equipment development. It is necessary to study the feasible reliability assessment methods in the laboratory in depth. Contents of the invention [0003] The purpose of the...
