摘　　要：运用可靠性设计理论和优化设计技术 ,提出了液体动压径向滑动轴承的概率优化设计方法 ;建立了其概率多目标优化设计的数学模型 ;求解该模型 ,可得到总体最优的设计方案 ,使轴承在满足承载能力及强度要求条件下 ,功耗和温升最低 ,体积减小。According to the reliability theory and the optimal design principle, a multi-aim probability optimal design method of hydrodynamical journal bearing is discussed in this paper. The establishment of mathematical model for this method is introduced in details. With solving the model, optimal parameters for falling bearing power waste and oil temperature are obtained. The calculation results show that this optimal design method is effective.
