Analysis of electromechanical systems based on the absolute nodal coordinate formulation [PDF]

Acta Mechanica, 2022
AbstractThe absolute nodal coordinate formulation (ANCF) approach has been successfully used to analyze bodies undergoing large deformations in multibody dynamics applications. In this study, the ANCF is extended to the analysis of coupled electromechanical systems.

Dynamic Contact between a Wire Rope and a Pulley Using Absolute Nodal Coordinate Formulation

Machines, 2016
Wire rope and pulley devices are used in various machines. To use these machines more safely, it is necessary to analyze the behavior of the contact between them. In this study, we represent a wire rope by a numerical model of a flexible body.
