Embodiment Construction

[0074] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0075] figure 1 is a method flowchart of a reliability evaluation method provided by an embodiment of the present invention, such as figure 1 As shown, the reliability assessment method includes:

[0076] Step 101, obtaining test parameters obtained through special reliability tests and debugging tests.

[0077] Among them, the test parameters include the debugging test time of the equipment after the technical state is solidified, the number of equipment failures in the debugging test, the time of the special reliability test, and the number of failures of the equipment in the special reliability test.

[0078] Specifically, the technical state refers to the physical and functional characteristics specified in the technical document...

Abstract

The invention discloses a reliability evaluation method and a device, belonging to the field of equipment reliability design. The method comprises the following steps of: obtaining test parameters obtained through reliability special test and debugging test, the test parameters include the debugging test time of equipment after technical state solidification, the failure times of equipment in thedebugging test, the reliability special test time and the failure times of equipment in the reliability special test; Determining the environmental conversion coefficient of the equipment; The total time of equivalent reliability test of equipment is determined according to the environmental conversion coefficient and test parameters of the equipment. According to the total time of equivalent reliability test and test parameters, the mean time between failures of the equipment is determined. The reliability of the equipment is determined according to the mean time between failures of the equipment and the typical task time of the equipment. This evaluation method effectively combines the test parameters of special reliability test with the test parameters of commissioning test, which not only ensures the reliability of reliability evaluation, but also reduces the cost of special reliability test.

Description

technical field [0001] The invention relates to the field of equipment reliability design, in particular to a reliability evaluation method and device. Background technique [0002] Reliability is the ability of the product to complete the specified function under the specified conditions and within the specified time. MTBF and reliability are commonly used as reliability indicators to measure the reliability level of equipment. [0003] When evaluating the reliability of equipment, it is necessary to conduct special reliability tests on the equipment to obtain relevant parameters, and then calculate the mean time between failures and reliability of the equipment based on the relevant parameters to judge the reliability of the equipment. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Since the reliability special test is a long-term assessment test, the longer the reli...
