Hydraulically driven mechanisms
give rise to a combined flexible multibody system and fluid circuit system.
In this work the flexible multibody system
is modeled using the unconstrained extremum principle of Simo
This is based on large displacement and rotation theory
and yields a non-linear ODE of second order with constant mass matrix.
The combined system is solved
by a single L-stable implicit Runge-Kutta ODE integrator.
