Reliability Analysis for System with Random Failure Threshold
Based on the degradation model and failure threshold probability distribution,the reliability analysis for system with random failure threshold is presented in this paper.The actual failure point of engineering system is unpredictable or random because of the system’s various uncertainties; which bring us a challenge to consider this problem in practical reliability analysis.An integrated methodology for reliability analysis with random failure threshold is developed in this paper,and both the degradation rate and the failure threshold uncertainty are considered in the deduction process.Moreover,the reliability analysis procedure for system with random failure threshold is given based on this method.In the end,the developed reliability analysis is demonstrated by an electro-hydrostatic actuator (EHA) system application example.
