Design and Finite Element Analysis of a New Type of Plum Coupling

利用新型高性能复合工程橡胶和铝合金的优点,设计了一种新型的梅花联轴器。对梅花联轴器的结构进行了参数设计。利用SOLIDWORKS建立了联轴器三维模型。基于橡胶材料超弹性本构模型～Moo-ney～Rivlin模型,利用ABAQUS对梅花联轴器的静态扭转特性进行了有限元仿真分析。结果表明该联轴器的扭转刚度和强度符合设计要求,联轴器的关键部件:金属块～橡胶复合弹性体会沿周向产生较大变形,能很大程度地过滤掉非稳态波动干扰,该联轴器具有很好的工程应用价值。

A new type of plum coupling was designed by using the advantages of both the new high-performance composite engineering rubber and the aluminium alloy. Structure parameter of the plum coupling was got by calculation. SOLIDWORKS was used to build the 3-D model of the plum coupling. On the basis of rubber material hyper elastic constitutive model （Mooney-Rivlin model） , ABAQUS was used to carry out finite element simulation analysis for the static torsional properties of the plum coupling. The results show that the torsional stiffness and strength of the coupling can meet the design requirements. The key components （ metal-rubber composite elastomers） of the coupling can pro-duce a larger deformation around circumferential direction, it can filter the interference of non-steady-sta（e fluctuations to a large extent. The coupling has a very good application value in engineering.
