单目标二级斜齿轮减速器的模糊可靠性优化

Single-objective Fuzzy Reliability Optimization of the Two-stage Helical Gear Reducer

可靠性优化设计是一种现代设计方法,与常规的设计方法相比其工程实用价值高、方法先进,但由于工程设计中存在大量的模糊因素,而这些因素往往会使一些真正的最佳优化方法被漏掉,因而在设计中考虑到一些模糊因素的影响也是不容忽略的。为使二级斜齿轮减速器设计更加合理,基于可靠性理论与模糊数学的基础,对减速器进行了优化设计。

Compared with the conventional design method, reliability optimization design is a advanced modern design methods and has high practical value. But there are a lot of fuzzy factors in engineering design that may lead some real best optimization method to be omitted. So influence of some fuzzy factors in the design should not be ignored. To realize the reasonable design of the two-stage helical gear reducer, optimal design of the reducer is carried out based on reliability theory and fuzzy mathematics.
