Torpedo Reliability Growth Testing And Analysis Methods

Reliability growth test and synthesis reliability growth analysis are researched in this thesis, combining the condition of torpedo products, using various testing information and resource as more as possibly.This paper will mainly research the theory and method of the reliability growth test about the torpedo products. The main productions and innovative points are as follows:1. Reliability growth test method is researched,including test environmental congditions and typical failure factors,and the environmental stress screening according to synthetical reliability growth management strategy.2. Based on the traditional reliability growth test, considering the practical condition of complex equipment, the Extended Crow Model is introduced into complex equipment reliability growth research. Then precise growth analysis and expression of estimate key parameters are given, adopting weighted average effectiveness factor and environment conversion factors.3. Build up the multiple environments analysis method for torpedo products, so the synthetical testing data from multiple environments is introduced to analyze its reliability growth . And the given method can solve the arised problem appropriately. Then, based on the Compertz Model, particular exertion contraposing testing data is exhibited.4. Based on the failure modes and fuzzy failure types, considering the practical condition of torpedo products,, the environmental testing and test items are designed. Analysis and evaluation of torpedo products performance in the task environment is presented, adopting reliability growth analysis.
