In friction elements for the revolute joints, a coefficient of friction ÎĽ and the relevant pin diameter are specified. The resulting friction forces depending on the current joint forces then have a direction-dependent effect on the required actuating force on the cylinder. The friction model is based on Coulomb’s law of friction.
A diagram shows the actuating forces on the cylinder that are ideally required to carry out the modelled opening movement (in comparison: with and without friction effects, for opening and closing).Â
Modifications and corrections to the starting and ending positions of the landing gear can therefore be done quickly, even while friction is considered. If the end position should also be held fixed by the system, a kinematic multi-plane synthesis could also be added to the present model.
