Considering the influence of random factors, using the HL-RF method
to calculate the reliability, the reliability optimization design of the gearbox is studied.
The reliability optimization design of the gearbox is studied by using the importance
sampling. This paper puts forward the method of reliability fuzzy optimum design,
which is the deepening of reliability, optimum design, and fuzzy optimum design.
Under the influence of fuzziness, a multi-objective reliability fuzzy optimization
model of the gearbox is established. By using the multi-objective fuzzy optimization
method, the reliability fuzzy optimization design of the gearbox is carried out.
