ASSESSMENT METHOD OF RELIABLE LIFE BY ZERO-FAILURE EXPERIMENTS OF SMALL SAMPLE COMPONENTS

LU Shan~1 LU HongYan~2 (1.School of Power and Energy,Northwestern Polytechnical University,Xi′an 710072,China) (2.Department of Mechanical Engineering,Nanchang Institute of Aeronautical Technology,Nanchang 330034,China)$$$$  
The theoretical formulas of the design method were deduced for experimental assessment of reliable life by small samples with the two-parameter Weibull distribution. And coefficient tables were given for experiment design of reliable life with the confident degree being 95% and the ones could be obtained with the confident degree being any percentage, if needed by the formulae given. For the given reliability of life and the specimen number, desired test time can be determined. And for the given reliability of life and the test time, desired specimen number can be determined. Considering the costs of specimens and experiments, a cost optimal for a reliable life test can be designed.
