Vehicle dynamics simulation based on multibody dynamics techniques has become a powerful tool for vehicle systems analysis and design. As this approach evolves, more and more details are required to increase the accuracy of the simulations, to improve their efficiency, or to provide more information that will allow various types of analyses. One very important direction is the optimization of m...

Multibody systems can be either closed-loop or open-loop controlled. While closed-loop control clearly is the most flexible solution applicable to most systems and motions, some significant drawbacks exist: It requires sophisticated and expensive sensory systems and feedback-controllers. The computation of appropriate reactions is time critical and often a limitation for making the motion of a ...

The RifSimp package in Maple transforms a set of differential equations to Reduced Involutive Form. This paper describes the application of RifSimp to challenging real-world problems found in engineering design and modelling. RifSimp was applied to sets of equations arising in the dynamical studies of multibody systems. The equations were generated by the Maple package Dynaflex, which takes as ...

Many mechanical systems such as vehicles, robots and space structures are comprised of a lot interconnected components. The motion the components is constrained because joints or specified trajectories. Multibody dynamics one effective methods to analyze nonlinear dynamic behavior for systems. On other hand, it quite difficult obtain all parameters required numerical simulation by only direct m...

Flexible Multibody System Dynamics (FMSD) is a simulation technique that can be used to study the behavior of the mechanical systems that consists of one or more deformable bodies. A deformable body can be modeled using a number of approaches while the floating frame of reference formulation is a widely used approach. In that approach, flexibility within Multibody System Dynamics (MSD) is descr...

A new formulation of the equations of motion of constrained multibody systems is presented using a coordinate-splitting (CS) technique. In contrast to the conventional index reduction techniques which apply diierentiation to the Lagrange formulation, this approach applies the coordinate-split operator to the variational form of constrained dynamics, yielding consistent dynamic equations of mult...

The application of linear graph theory to the modelling of flexible multibody systems is described. When combined with symbolic computing methods, linear graph theory leads to efficient dynamic models that facilitate real-time simulation of systems of rigid bodies and flexible beams. The natural extension of linear graphs to the modelling of mechatronic multibody systems is presented, along wit...
