A Common mode for calculating the kinematics of mechanism activated with hydraulic cylinders

Résumé

The actuation of the mechanisms using the hydraulic cylinders is performed because they can achieve large forces at small dimensions and have small relative masses. The increase of the computing power has made possible a mathematical modelling closer to the reality of the behaviour during the work of this type of mechanical-hydraulic systems.
There are still difficulties in approaching the construction of the models because of the variety of mechanical systems, the different types of hydraulic cylinders used and the types of simpler or more complex hydraulic schemes used.
This work aims at achieving a uniformization of the approach of the models of mechanisms used in the case of the use of different technical solutions of construction and of location of hydraulic cylinders.
