Nonparametric Statistical Analysis of the Reliability of Life Test under Constantly Accelerating Stress |
| |
| Abstract: | For more reasonably evaluating the reliability of products, the authors put forward the method of nonparametic statistical analysis of reliability. By which the data information of life test under constantly accelerating stress, three valuable data information including failure number and failure time and effective number can be fully utilized; and the imperfection of utilizing only failure number and failure time, as the method of traditional analysis does, can be perfected. The main contents include formula for estimating k ; demonstration of P k>P k+1 ; statistical analysis of life under constantly accelerating stress; parametric estimate of life distribution; and case calculation and comparison. |
