Abstract

The invention provides a determination method for storage degeneration representation parameters of a permanent magnet of an electromagnetic relay. The method comprises the steps that dynamic characteristic simulation of the electromagnetic relay is realized; a storage degeneration model of the permanent magnet is established; a data collection moment of a test is substituted into the storage degeneration model of the permanent magnet, and a corresponding storage degeneration state of the permanent magnet is obtained; corresponding parameters of an electromagnetic system simulation model are modified according to the storage degeneration state of the permanent magnet at all moments, and injection of storage degeneration of the permanent magnet is realized; dynamic characteristic simulationis performed on an electromagnetic relay simulation model where different storage degeneration degrees of the permanent magnet are injected; external characteristic simulation degeneration data is fitted, and storage degeneration models of all external characteristics are constructed respectively; trend analysis is performed on the constructed storage degeneration models of the external characteristics; and whether selected output characteristics are the storage degeneration representation parameters of the permanent magnet of the electromagnetic relay is determined. Through the method, the problem that the degeneration degree of the permanent magnet of the electromagnetic relay in the storage process cannot be directly monitored is solved.

Description

technical field [0001] The invention relates to the technical field of performance analysis of relay products, in particular to a method for determining characteristic parameters of permanent magnet storage degradation of electromagnetic relays. Background technique [0002] After the production and delivery of most products, their performance and reliability will not only be affected by the working stress, but also will be affected by the combined effect of the storage environment stress in the non-working state. For single-use products such as automotive airbags, missiles, and launch vehicles, the storage state occupies most of the entire life cycle, and the continuous effects of environmental stresses such as temperature, humidity, and vibration during the storage process cause The most important factor for its performance degradation. Therefore, the related fields of reliability research are receiving more and more attention on the performance degradation of products du...
