【摘要】：为研究叠片联轴器挠性元件的应力特性,建立叠片组的接触有限元模型,得到了综合载荷下的应力云图。利用有限元分析软件Ansys,建立叠片组的几何模型,在膜片间添加接触对,并给出了不同载荷的施加方法。分析了片数变化对叠片组应力的影响,得出从四层到九层膜片的叠片组的最大等效应力和最大接触应力的分布曲线。分别研究了在综合载荷作用下转矩、轴向位移和角向位移等单一载荷的变化对叠片组的应力影响情况,得到叠片组中每层膜片的最大等效应力和膜片间最大接触应力分布曲线。研究表明,在各种载荷作用中,角向位移的变化对叠片组应力的影响最大,且综合工况下叠片组的破坏首先发生在外侧膜片垫圈周围。有关节轴承的叠片联轴器相对于普通的叠片联轴器,有更强的角向补偿的能力,关节轴承的存在提高了叠片联轴器承受载荷的能力和叠片组的使用效率。
[Abstract]:In order to study the stress characteristics of flexible elements of laminated couplings, a contact finite element model of laminated coupling was established, and the stress cloud diagram was obtained. By using finite element analysis software Ansys, the geometric model of laminated plates was established, the contact pairs were added to the diaphragm, and the methods of applying different loads were given. The effect of the number of sheets on the stress of laminated laminates is analyzed, and the distribution curves of maximum equivalent stress and maximum contact stress of laminated group from four layers to nine layers are obtained. The effects of single load, such as torque, axial displacement and angular displacement on the stress of laminated laminates under the combined load are studied respectively. The maximum equivalent stress and the maximum contact stress distribution curve of each layer diaphragm in the laminated group are obtained. The results show that the change of angular displacement has the greatest effect on the stress of the laminated group under various loads, and the damage of the laminated group first occurs around the outer diaphragm washer under the comprehensive working conditions. The laminated coupling with joint bearing has stronger angular compensation ability than the common laminated coupling. The existence of joint bearing improves the ability of laminated coupling to bear the load and the efficiency of lamination.
