Kineto-elastodynamic analysis of hose cutting mechanism of an aluminum electrolytic capacitor casing machine

Abstract

The kineto-elastodynamic (KED) model of a hose cutting mechanism used in the aluminum electrolytic capacitor (AEC) casing machine is developed to investigate the dynamic characteristics. According to the composition characteristics, the cutting mechanism is divided into cam-roller and linkage two substructures. And the dynamic models of the two substructures are established using the lumped parameter method and finite element method (FEM), respectively. In the model, the compliances of the camshaft and the links are taken into consideration. The elastic displacement of the links, angular error of the cutter and the dynamic stress of the links are analyzed based on the KED model. The results provide important information for structure optimization and vibration control of the mechanism.
