Abstract
The reliability test of weapon loading often produces failure free test data. By making use of the memoryless of exponential distribution, it is generally considered that the failure free test time ofn same-type products is equal to the total test time ofn products for one product to work without failure. In engineering applications, however, this method has limitation. This paper explains the reason why this method cannot be fully used for calculation by making use of the bathtub curve, that is, there is a mistake when the total load time is up to the failure condition. To solve this problem, a modified method for calculating the reliability of loading is proposed, and the lower confidence bound is given. The feasibility of the proposed method is verified by an example.关键词
