Evolution of the DeNOC-based dynamic modelling for multibody systems [PDF]
Mechanical Sciences, 2013 Dynamic modelling of a multibody system plays very essential role in its analyses. As a result, several methods for dynamic modelling have evolved over the years that allow one to analyse multibody systems in a very efficient manner.
