Abstract:

The ECS design procedure is expounded by means of reliability prediction and allocation, FMECA analysis and FTA analysis, The reliability appraisal test of product in line with non exponent distribution under composite stress is introduced in detail. The reliability design and evaluation of an ECS have been accomplished for the first time in our conutry. In addition, the evaluation method of reliability index of product with non exponent distribution is presented with ECS as the example.
