Consideration about Elastic Couplings Modeled in CATIA

Abstract:

This paper refers to an elastic shaft coupling named Vulkan coupling, with its general behavior. Vulkan shaft couplings link two shafts in diesel-engine and electric drives. They are simple from the construction point of view, are easily mounted and dismounted. Parts and assembly modeling, preprocessing, processing and post processing can be performed using all leading CAD tools, like CATIA. The main goal of this work is to generate a finite element model for a Vulkan coupling, using FEM Solid (FMD). For the demonstration, a Vulkan coupling with a torque of 350 Nm has been chosen. At the end of the modeling with finite element, it results that, for intermediate coupling elements with mechanical material properties very different from those of steel components, MEF analysis with rubber parts only is to be preferred. The other components can be simulated using the virtual rigid elements.
