Simulation methods of rigid holonomic multibody systems with bond graphs

Contact Graphs in Multibody Dynamics Simulation

For this costumer placed in Belfast, UK, simulation has been used to investigate the manufacturing process, to evaluate bottlenecks and to prepare the background for simulation based, in-line scheduling. The actual problem at the shop floor deals with synchronizing work flows and optimizing production in conjunction with customer orders . Over 1700 different kinds of orders can be manufactured ...

Modeling and Simulation of Hydraulic Systems by Bond Graphs

This paper describes a unified approach to modeling and simulation of hydraulic systems using bond graphs. Unlike the others, the causalities are not applied in bond graph settings. This leads that mathematical model is generated in the form of differential algebraic equation (DAEs) and solved as such by suitable solver. Bond graph model of simple hydraulic system has developed using program Bo...

Iterative Rigid Multibody Dynamics

The simulation of large rigid multibody systems is a challenge. Collisions and friction constraints cause non-smooth motions of the rigid bodies. Differential complementarity problems are therefore used to formulate the dynamical system. The efficient solution of such problems is difficult and the major focus of this thesis. Several modeling choices of varying accuracy and difficulty are presen...

Rigid multibody system dynamics with uncertain rigid bodies

This paper is devoted to the construction of a probabilistic model of uncertain rigid bodies for multibody system dynamics. We first construct a stochastic model of an uncertain rigid body by replacing the mass, the center of mass and the tensor of inertia by random variables. The prior probability distributions of the stochastic model are constructed using the maximum entropy principle under t...
