A New Parameter Estimate Method for Invariable Stress Accelerated Life Test

摘要

This paper presents a new data processing method for the invariable stress accelerated life test of electrical apparatus whose invalidation distribution type is Weibull Distribution. The point estimate value of electrical products' reliability parameter can be accurately got from the new method that combines the non-error linear estimate method and maximal legitimacy like estimate method. Furthermore using the approach can greatly simplify the calculation. A calculating example in this paper shows that the method has much accuracy than the non-error linear estimate method and is efficient for some applied problems.
