English abstract:
We consider the dynamics of a double spring pendulum
with very stiff springs. Contrary to a single spring pendulum
numerical simulations show an unexpected large influence
of the fast longitudinal oscillations on the slow pendulum
oscillations even for extremely large values of the
stiffness.
In order to understand the transition from the regular
quasiperiodic motion to the apparantly chaotic behaviour
we investigate the dynamics of the simplified Normal Form
equations.
