To improve the efficiency of Monte Carlo simulation applied to evaluating the common cause failure probability of complex mechanical system, the concept of system fatigue life PSN curve was set up first, and then a Monte Carlo method for system reliability assessment based on this concept was proposed. With a given constant load, based on the correspondence of probability percentiles between specimen fatigue lives associated with different cyclic stress levels, every single PSN curve of component can be extracted stochastically. According to the linear cumulative damage rule and the corresponding system reliability model, the fatigue life distribution of gear-series-system was acquired. System PSN curve can be obtained by fitting constant load and life distribution. The system can be treated as a component, and the life analysis process of component-system-component has been completed. By means of damage equivalence principle between random load and constant load, the problem of reliability assessment of a complicated series system under random load can be converted to the problem of reliability assessment of component under constant load.
