Aim\ Reliability prediction is of most importance to the improvement of the reliability of systems. Method\ In this paper
stress analysis
one of the methods of reliability prediction
is used to analyze the working conditions of every component in the circuit of the Electronic Crusher Gauge in special state. Therefore
the whole working failure rate and MTBF (Mean Time Between Failure) of the circuit of the Electronic Crusher Gauge are calculated. Result\ The results indicate that actual status agrees with theoretical analysis excluding the effects of soldering
encapsulating and other technical process. Conclusion\ The reliability prediction method provided in this paper is available for reference and practicable.
