Multiobjective fuzzy optimization design of hydrodynamic sliding bearing

本文就液体动压滑动轴承的设计问题 ,根据模糊方法学的基本理论 ,研究目标函数、约束条件和设计变量都具有模糊性的全局优化问题 ,建立了该问题的多目标模糊优化设计的数学模型 ,获得比常规设计更佳的承载能力与工作状态。

Based on fuzzy theory, this paper discusses the design problem of hydrodynamic sliding bearing and studies the overall optimization problem about fuzzy objective function, constrained condition and design variable. A mathematical model of multiobjective fuzzy optimization design of the problem is constructed. It is demonstrated that the model can obtain better running condition and loading capacity than conventional methods.
