Why calculate MTBF of SmCo magnet?
MTBF, the mean time between failures, is the average value of the time from when a new product starts working under specified working environment conditions to the first failure. The longer the MTBF, the higher the reliability and the stronger the ability to work correctly. The unit is "hours". It reflects the time quality of the product and reflects the ability of the product to maintain its function within the specified time.
Specifically, MTBF refers to the average working time between two adjacent failures, also known as the mean time between failures. It only applies to serviceable products. At the same time, it is also stipulated that the ratio of the cumulative working time to the number of failures in the total use phase of the product is MTBF. Generally, the MTBF of disk array products cannot be lower than 50,000 hours. The MTBF value is an important parameter to be considered when designing a product. Reliability engineers or designers often use various methods and standards to estimate the MTBF value of a product.
The followings are the purpose of MTBF analysis.
(1) It is the key countermeasures for high-frequency faulty parts and the technical transformation basis for prolonging the life of parts.
(2) In order to calculate the life cycle of parts and prepare the best maintenance plan.
(3) Selection of inspection objects and items and setting and improvement of inspection standards.
(4) It is used to guide the distribution of internal and external maintenance work.
(5) To set the standard for spare parts.
(6) As a reference for selecting the improvement focus of maintenance technology methods.
(7) It is used to set the estimated operating time standard for equipment objects, and the selection of maintenance operations and the research on maintenance time standards.
(8) As a reference for drawing arrangement and re-selection of key equipment or parts.
(9) Setting and revising operation standards and assigning responsibilities for determining equipment maintenance business.
10) Provide technical information on equipment reliability and maintainability design.
