NEW APPROACH TO ESTIMATING THE CONSTANT-STRESS ACCELERATED LIFE TEST

摘要：

The least square method has been widely used in fitting accelerated model when estimating the constant-stress accelerated life test, but it could perhaps bring a great error in model fitting and extrapolation. A new derivative fitting and extrapolation method was used to fit both the test data and its derivative well and the development trend of the model curve could be well described. Therefore, a reasonable prediction would be given to improve the precision of life estimation.
