Structure-Preserving Model Reduction for Mechanical Systems
Mechanical Systems Model Reduction
2015/6/19
This paper focuses on methods of constructing of reduced-order models of mechanical systems which preserve the Lagrangian structure of the original system. These methods may be used in combination wit...
Tippe Top Equations and Equations for the Related Mechanical Systems
tippe top rigid body nonholonomic mechanics integrals of motion stability gliding friction
2012/4/26
The equations of motion for the rolling and gliding Tippe Top (TT) are nonintegrable and difficult to analyze. The only existing arguments about TT inversion are based on analysis of stability of asym...
Conditions for the feasibility of multiple rolling for mechanical systems with multiple contact points
mechanical systems multiple contact points Conditions for the feasibility of multiple rolling
2011/9/1
We illustrate a theoretical procedure determining necessary conditions for which simultaneous pure rolling kinetic constraints acting on a mechanical system can be fulfilled. We also analyze the suffi...
Cartesian approach for constrained mechanical systems
Cartesian approach constrained mechanical systems
2010/11/19
In the history of mechanics, there have been two points of view for studying mechanical systems: Newtonian and Cartesian.
According the Descartes point of view, the motion of mechanical systems is ...
