Analysis of Rotating Systems Using General-Purpose Multibody Dynamics

This work illustrates the application of general-purpose multibody formulations to the analysis of rotating systems dynamics. Various benchmark problems encompassing multiple deformable components are presented and analyzed. The suitability of the approach is assessed and conclusions are drawn on the basis of correlating the numerical simulations with analogous examples from the open literature

Approaches to Fibre Modelling in the Model of an Experimental Laboratory Mechanical System

In this paper there are presented some possible approaches suitable for the modelling of the fibre and cable dynamics in the framework of various mechanical systems: force representation of a fibre, a point-mass model and an absolute nodal coordinate formulation. Experimental measurements focused on the investigation of the fibre behaviour were performed on an assembled weight-fibre-pulley-drive laboratory mechanical system. This mechanical system was modeled using all of the mentioned methods (newly using point-mass model) and simulations of the experimental measurements were performed. Results obtained using simulations and experimental measurements are compared and discussed
