Flexible multibody dynamics is often approached in case of small flexible deformations by means of the finite-element modelling method in component mode synthesis techniques to reduce the size of the computations. In this work, by means of proper shape functions bases, the elastic behaviour of slender beams is approximated in its local axial and transversal displacement components. Attention is paid to the inertial contributions to enhance the driving function. An ideal quick return mechanism is here modelled with the meshless approach. The results of different modelling choices are collected, to show how this shape functions based formulation can handle the added flexibility by means of a small set of degrees of freedom and motion equations. Some aspects are detailed and discussed.

Abstract

Flexible multibody dynamics is often approached in case of small flexible deformations by means of the finite-element modelling method in component mode synthesis techniques to reduce the size of the computations. In this work, by means of proper shape functions bases, the elastic behaviour of slender beams is approximated in its local axial and transversal displacement components. Attention is paid to the inertial contributions to enhance the driving function. An ideal quick return mechanism is here modelled with the meshless approach. The results of different modelling choices are collected, to show how this shape functions based formulation can handle the added flexibility by means of a small set of degrees of freedom and motion equations. Some aspects are detailed and discussed.
