摘　　要：叠片联轴器工作时经常会受到转矩、离心力、轴向位移和角向位移的作用,对叠片联轴器在以上各种载荷下的应力分析,能够为动力装置的安全运行提供可靠保证。建立了考虑叠片之间接触影响的六孔束腰型叠片联轴器有限元模型,分析了联轴器在转矩、离心力、轴向位移和角向位移单独作用下的叠片应力大小和分布特征,并通过改变螺栓的预紧力和叠片间的摩擦因数,研究了它们对联轴器应力特性的影响。结果表明,增大螺栓预紧力和摩擦因数会导致联轴器在转矩、轴向位移和角向位移作用下最外层叠片的最大等效应力值增大,但对离心力作用下的应力影响不大。Laminated couplings are often subject to torque,centrifugal force,axial displacement and angular displacement during operation.The stress analysis of the laminated couplings under various loads can provide a reliable guarantee for the safe operation of the power plant.The finite element model of the six-hole tightwaist laminated coupling considering the contact between the laminated plates is established.The stress value and stress distribution characteristics of the laminated plate under the single effects of torque,centrifugal force,axial displacement and angular displacement are analyzed.And by changing the preload force of the bolts and the friction coefficient between the lamination,their influence on the stress characteristics of the coupling is studied.The results show that increasing the bolt preload and friction coefficient will cause the maximum equivalent stress value of the outermost laminate to increase under the action of torque,axial displacement and angular displacement,but it has little effect on the stress under centrifugal force.
