| Abstract: | On the basis of theoretical distributions, the theory of cutting off tail distribution at two ends was proposed. Also, methods to find out cutting off points of various design parameters and under various conditions were discussed. Recently, stress strength interference model is widely used in reliability design of mechanical components. To fit for practical use, stress strength interference model of cutting off tail distribution was set up in this paper. Calculating formulae of reliability in combining cutting off tail stress and strength under various distributions has been given, which is very convenient for practical use. |
