The Determination of Reliability Test Times for Dynamic Mechanism

Abstract:

In this paper, the dynamic mechanism is taken as an example for research sample size definition in Reliability Compliance Test and the Durability (Life) Test. When the fatigue life distribution is unknow, the test can be considered as a kind of success-failure test, which sample size is followed by binomial distribution. According to the central limit theorem, when the sample size is very large, it is followed by the Normal Distribution. When the two reliability targets and confidence degree were given, the total times of the test and the maximum times of the failure test can be calculated. In life test, the key point is to transform the test time into times of test.
