提升机主轴疲劳强度的模糊可靠性设计

摘要

The fuzzy reliability theory was applied to fatigue strength design of main shaft of hoist and its fuzzy relia- bility mathematical model was established. Besides, the design method was described and the examples of calcula- tion were given, and then the Comparison of examples illustrates the reasonability and advancement of fuzzy reliabil- ity design.%将模糊可靠性理论应用于提升机主轴的疲劳强度设计中,建立了提升机主轴疲劳强度的模糊可靠性设计数学模型,介绍了它的设计方法,并给出了算例。算例中通过分析比较,说明了模糊可靠性设计的合理性和先进性。
