| Abstract: | According to fuzzy mathematics and reliability designtheory,the fuzzy reliability mathematical model of fatigue strength of V-belt transmissionis set up.Its fuzzy reliability design method is discussed when both random variables andfuzzy variables exist at the same time,taking allowable stress as random variable andworking strength as fuzzy variable.The results show that the fuzzy reliability is moreadaptable to reflect the working status really than the random reliability,that thereliability of V-belt transmission can be advanced by using fuzzy reliability designmethod.2tabs.,6refs. |
