Abstract

A motion simulation system includes actuators having a planetary gearbox engaged with and driven by a servomotor engaged with a crank. A connector rod has a proximal end engaged with the crank of each actuator, and a distal end engaged with a top plate configured to attach to a platform assembly. A control system is operable with each electric servo motor of each actuator for delivering control for providing a simulated motion to the top plate. Control data is sent to the servomotors using a msec data send and receive rate, with internal processing within the nano-second range. Such update rates coupled with a real time, dynamically responsive motion controller results in a desirably smooth and accurate simulator motion. The control system includes a washout filter for transforming input forces and rotational movements. One to six degrees of freedom systems having smooth performance with high payload capability are provided.

Dependent claims

A motion simulation system comprising:

a frame;
at least one connector rod having opposing proximal and distal ends thereon, wherein the distal end of the at least one connector rod is rotatably connected to the frame;
at least one actuator including:
a motor/gearbox assembly having a servomotor operable with a planetary gearbox and shaft driven thereby;
a crank arm having a proximal end fixedly attached to the shaft for rotation thereby, and a distal end rotatably connected to the proximal end of the connector rod;
a base;
and
a support having a proximal end affixed to the base and an opposing distal end affixed to the motor/gearbox assembly for fixedly attaching the motor/gearbox assembly in spaced relation to the base;
and
a controller operable with the at least one actuator for providing an electric signal to each of the servomotors for providing a preselected motion to the at least one connector rod and thus the frame, wherein the control system directs input forces and rotational movements into positions of the frame.
