FUZZY RELIABILITY ANALYSIS OF COMPLEX MECHANICAL SYSTEM

摘要

In the paper, modeling for simulating fuzzy reliability of mechanical system based on the operator of fuzzy set in fuzzy mathematics is given. Approaches for establishing membership functions of fuzzy safe events are discussed, and the approach 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 failure event of mechanical system can be calculated according to the above obtained membership function, and fuzzy reliability of complex mechanical system can be analyzed. An example is given to prove it feasible the digital simulation approach
