|Here we present a dynamical simulation of a hydraulic constant tension [CT] system in SimulationX.
The purpose of the simulation is to check the similarity of the simulated system and the real system.
The real system is a 10 ton winch with CT function where the results from this test are compared with
the results of the simulated system.
We have successfully tested the winch system with CT function. This was done using pressure
transmitters and flow sensors placed on the hydraulic motor blocks in combination with a load cell and
a winch encoder to measure its behavior. All data from these sensors were logged and saved to later be
compared with the simulated system.
Our method to simulate the model in SimulationX proved to be a successful approach to achieve a real
simulation of the CT system; this is because of the variable throttle valve function in SimulationX.
With this valve function we control the system behavior by adding equations to the stroke signal of the
variable throttle valve.
Our main result of the CT system is of great significance to all users working with hydraulic operated
systems and dynamical modeling. Because of the variable throttle valve function in SimulationX it is
possible to do complex dynamical models of advanced hydraulic systems such as CT systems. This
approach also helps to understand CT systems in depth.
