Abstract:

How to reasonably estimate torpedo failure time under storage state is an important problem in the research of storage reliability for torpedo. Based on the existing three failure time estimation methods which are used to analyse other weapons, by generating fault flow that fits torpedo failure law under storage state, the torpedo failure time is estimated by applying the three methods, respectively. Further the corresponding storage availability deviation values of three methods are calculated, and useful results are obtained through comparative analysis. An actual example presents that the inspect time method is not applicable for the calculation of torpedo storage reliability, while the equally divided interpolation method and the equally divided center interpolation method can produce good effects. In comparison, the equally divided interpolation method is better, and it can satisfy calculation demand of torpedo storage reality analysis in engineering.
