But the system has proved itself to require very little maintenance.
With up to 90 kg on its back, the simulator’s six roller screws are subjected to considerable mechanical strain. For us, the problem was how to make it small enough to fit under something the size of an actual horse,” comments Jean-Louis Jouffroy, who headed the project to build the horse simulator. “It’s a classic arrangement for simulators, only miniaturised. A linear potentiometer regulates the precision of the movements.Ĭontrolled by a computer, the arrangement can accurately recreate any movement a horse can make. Each “leg”‘ is propelled by an SKF linear actuator driven by planetary roller screws via an electric motor. The actuators link a triangular plate on the floor to another triangle offset by 60 degrees that is fixed under the horse’s body. The movement of the horse simulator at the French National Equestrian School is derived from the action of six SKF linear actuators with roller screws.
