Abstract: A new dynamic model for mixed, flexible bar and gear multibody
systems is developed based on a specific finite element method,
and a new gear-element is proposed. The gear-element can take
into account the time variant stiffness, the gear errors and
mass unbalance. The model for geared multibody systems can
couple the gear meshing and the flexibility of all contained
components. The kinematic and dynamic analyses of the geared
multibody systems are expounded and illustrated on an example
composed of three gears, two bars and one slider.
Key words: Gear Finite element Multibody system Simulation Dynamics
