A Non-Arrhenius Model for Mechanism Consistency Checking in Accelerated Degradation Tests

Degradation models are central to the lifetime prediction of electromagnetic relays. Coefficients degradation under accelerated test (ADTs) can be obtained experimentally, and it is customary map these coefficients back those describing actual by so-called Arrhenius model. However, for some components, such as springs in relays, model only appropriate over a certain ADT temperature range, which implies inaccurate mapping outside that range. On this point, an error function (EFM) proposed overcome shortcomings EFM derived from average vibration energy crystal, further related alongside constants. The empirical part paper compares 28-V–2-A results show superior characteristics Through mechanism consistency checking, also shown better option than Moving beyond case thought have applicability capacitors rubbers.
