Modeling Stiffness and Damping in Rotational Degrees of Freedom Using Multibond Graphs [PDF]
A contribution is proposed for the modeling of mechanical systems using multibond graphs. When modeling a physical system, it may be needed to catch the dynamic behavior contribution of the joints between bodies of the system and therefore to ...

Standing on a common ground: a comparison of static stability approaches for pallet loading
Abstract At the practical level, the static stability constraint is one of the most important constraints in practical pallet loading problems, such as air cargo palletizing. Approaches to modeling static stability, which range from base support and mechanical equilibrium calculations to physical simulation, differ in workflow, focus, and assumptions ...

A numerical coupling model for a multibody system with multiple lubricated clearance joints
In machines and mechanisms, most of the clearance joints are designed to operate with lubricant fluid, which is an effective way of ensuring better performance of the mechanical systems. The differently located lubricated joints interact with each other,

Analysis of servo-constraint problems for underactuated multibody systems [PDF]
Underactuated multibody systems have fewer control inputs than degrees of freedom. In trajectory tracking control of such systems an accurate and efficient feedforward control is often necessary.

Multibody Dynamics Model of a Human Hand for Haptics Interaction [PDF]
In this paper we propose a strategy for modelling a human hand for Haptics interaction. The strategy consists in a parallel computing architecture that calculates the dynamics of a hand; this is accomplished by computing the dynamics of each finger in a ...
