The proposed four ports cylinder was simulated and parameters such as ports sizes, loads and pressures are varied during the simulation.
The hydraulic resisting forces, piston speed and mass flow rates are computed. Chenoweth, Aircraft flight control actuation system design vol.
Finite element analysis is a method to computationally model reality in a mathematical form to better understand a highly complex problem. it is a method of determine the most efficient, low cost & reliable operation of a power system by dispatching the available electricity generation resources to supply the load on the system.
