Modeling viscous damping for transverse oscillations in reeving systems using the Arbitrary Lagrangian–Eulerian Modal approach

This paper contributes to a recently proposed Arbitrary Lagrangian–Eulerian Modal (ALEM) approach that makes it possible develop finite elements with variable volume suitable for modeling wire-ropes in reeving systems. Reeving systems often include motors continuously modify the total mechanical energy. If energy dissipation is omitted or underestimated computations, numerical solution may experience instabilities time domain. To eliminate this problem, main objective of research introduce simple Rayleigh based damping model into ALEM formulation. Simulations are carried out validate They demonstrate added wire ropes stabilizes domain, improves efficiency, and overall rigid-body motion not affected. • Viscous stability efficiency wire-rope Impact rope length on damped response negligible. Introduced does influence system.
