Theoretical analysis and numerical algorithm for frictionless multiple impacts in multibody systems
Using rigid body dynamics to solve multi-impact problems poses many difficulties and unanswered questions. Experiments and numerical simulation by using all kinds of compliant contact models clearly show that the outcomes of the post-velocities are not only influenced by the local dissipated energy, but also significantly effected by the coupling between various contacts. Based on the idea that...
متن کاملFrictionless multiple impacts in multibody systems . I . Theoretical framework
A new method is proposed that can deal with multi-impact problems and produce energetically consistent and unique post-impact velocities. A distributing law related to the energy dispersion is discovered by mapping the time scale into the impulsive scale for bodies composed of rate-independent materials. It indicates that the evolution of the kinetic energy during the impacts is closely associa...
متن کاملSymbolic Preprocessing for the Numerical Simulation of Multibody Dynamic Systems
The symbolic-numeric computing described here consists of an extensive symbolic pre-processing of systems of differential-algebraic equations (DAE), followed by the numerical integration of the system obtained. The application area is multibody dynamics. We deal symbolically with a DAE system using differentiation and elimination methods to find all the hidden constraints, and produce a system ...
متن کاملModeling Multibody Dynamic Systems With Uncertainties. Part II: Numerical Applications
This study applies generalized polynomial chaos theory to model complex nonlinear multibody dynamic systems operating in the presence of parametric and external uncertainty. Theoretical and computational aspects of this methodology are discussed in the companion paper “Modeling Multibody Dynamic Systems With Uncertainties. Part I: Theoretical and Computational Aspects”. In this paper we illustr...
متن کاملA Gluing Algorithm for Distributed Simulation of Multibody Systems
A new gluing algorithm is presented that can be used to couple distributed subsystem models for dynamics simulation of mechanical systems. Using this gluing algorithm, subsystem models can be analyzed at their distributed locations, using their own independent solvers, and on their own platforms. The gluing algorithm developed relies only on information available at the subsystem interfaces. Th...
