Abstract


The product of scientific reliability assessment can reduce costs , inspection rational design , optimize system design and shorten the research cycle. At present , the domestic structure is more complex, higher-priced assessment of measuring instruments has been in a blank state, therefore, AQSIQ established research project topic. Topic is \In this paper, LJ6010 versatile standard source for the study was carried out reliability evaluation . First, the counting method and stress method are combined multifunction standard source for LJ6010 reliability is expected to yield the corresponding reliability characteristic quantities , addresses the need for a preliminary assessment of the whole problem . Secondly, in order for LJ6010 versatile standard source for qualitative analysis , using the method of establishing fault tree ; For quantitative analysis , using a Monte Carlo simulation method used to solve the counting method and stress method is expected to analyze complex systems exist non- exponential distribution case, the calculation error is a big problem . Finally , the use of neural networks and nonlinear fitting self-learning features to aid reliability prediction assessment, failure to collect data related products on the basis of criteria established LJ6010 versatile source of BP neural network model to overcome the reliable assessment modeling difficult problem , and carried out simulation results proved method is feasible. Based on the different situations using different methods LJ6010 versatile standard source reliability evaluation , designed to explore practical engineering reliability assessment methods, assessment of the reliability theory and engineering practice, the reliability of measuring instruments for the assessment provides reference method .
