【Abstract】 In the paper, models for fuzzy reliability digital simulation of mechanical series system and parallel system based on the operators of intersection and parallel set in fuzzy mathematics are given. Approaches for establishing membership function of fuzzy safe event are discussed, and the approach of how to obtain the membership function of the fuzzy safe event from the known membership function of fuzzy strength based on the fuzzy probability theory is studied especially. Therefore, the value of the membership function of the fuzzy safe event of mechanical system can be calculated according to the above mentioned membership function, and fuzzy reliability of complex mechanical system can be analyzed. An example is given to prove that it is feasible for the models of digital simulation.更多还原
