摘要： The present disclosure provides a simulator for implementing smooth motion in multiple axes to implement various driving and flight environments in a real environment, and more particularly, a swing motion plate that has a structure stacked in multi stages, is configured so that each stage is stacked to implement movement on a different axis, but has a structure that allows each stage to move smoothly and without interruption in order to smoothly implement more realistic movements, and can drive a device by using a worm gear structure so that a load applied to the device is not concentrated when each stage drives each movement, and a motion simulator using the same.

The support structure is connected to the base (3), a pair of links (12,13) connecting the cranks (10,11) of shaft (5) to the moveable support (2). One crank (10) is positioned at one outer end (6) of the shaft (5) and the other crank (11) is positioned at the opposite outer end (7) of the shaft (5). Part of the rotating shaft (5) is the rotor (22) of the electric motor (21).

摘要： Miniature, portable motion platforms for simulating flight movements are described. Example portable motion platforms includes a base, a seat frame, and six actuators. The seat frame is configured to support a seat. The actuators are arranged in a Stewart platform configuration and are to move the seat frame relative to the base with six degrees of freedom. Each one of the actuators has a corresponding first end coupled to the base and a corresponding second end coupled to the seat frame.

摘要： Systems and methods include providing a virtual reality (“VR”) flight teleport system that includes a master aircraft and a plurality of remote slave aircraft connected through a network. A flight emulator in the master aircraft allows a user in the master aircraft to “teleport” into a remote slave vehicle in order to observe and/or assume control of the remote slave aircraft. Motion of, orientation of, and/or forces acting on the remote stave vehicle are emulated to the user of the master vehicle through a pilot control interface, a motion-control seat, and a head-mounted display to provide real-time feedback to the user of the master aircraft. Inputs made via the pilot control interface of the flight emulator system in the master aircraft are transferred through the network into the flight control system of the remote slave vehicle to control operation of the remote slave vehicle.

摘要： The invention is directed to an overdetermined movement platform system, comprising a base; a platform movable along 6 degrees of freedom relative to said base; at least eight long-stroke actuators, wherein each actuator couples the base with the platform and a controller which (a) is configured to adapt a demanded platform movement set-point to a commanded platform movement set-point, (b) is configured to move the eight long-stroke actuators such that the commanded platform movement set-point is achieved and (c) is configured to dynamically redistribute the forces as exercised by the actuators on the platform between the actuators.

摘要： A device that makes it possible to make the movements of moving platforms safer and relates more particularly to a linear actuator that can be used in a hexapod positioner supporting a load is provided. The actuator is actuated by electric control and comprises at least one hydraulic damper positioned on the actuator such that the forces generated by damping in the event of extreme breakdown are experienced only by the load and are distributed such as to limit force and acceleration peaks.

摘要： Systems and methods include providing a virtual reality (“VR”) flight emulator system that simulates control, operation, and response of a vehicle. The flight emulator includes a control interface and a head-mounted display worn by a user. Motion, orientation, and/or forces experienced by the simulated vehicle are imparted to a user through a motion-control seat. Multiple flight emulators can be connected to a communication network, and a master flight emulator may teleport into a slave flight emulator in order to observe, overtake, override, and/or assume control of the slave flight emulator. Inputs made via the control interface of the master flight emulator or during playback of a pre-recorded training exercise or flight mission are translated into the control interface, head-mounted display, and motion-control seat of the slave flight emulator to provide real-time feedback to the user of the slave flight emulator.

摘要： In a movement system, the movement limit is determined by having a degree of freedom of the movement system defined and the respective current movement system state being available. Subsequently, an articulation trajectory is determined for each upper articulation point of the movement system, on which articulation trajectory the articulation point can move along the degree of freedom. The movement limit is then derived by calculating the point of intersection of the actuator movement in an extreme deflection with its respective articulation trajectory.

摘要： A motion assembly that produces pitch and roll motions includes lower and upper plates. A pivotable coupling having upper and lower shafts extending from its center is coupled between the upper and lower plates. At least two linear actuators are coupled between the plates. Extension and retraction of the actuators pivots the upper plate about the pivotable coupling relative to the lower plate. A vehicle includes two steerable propulsion wheels coupled to a chassis. A lower plate of a pitch and roll assembly, similar to that just described, couples to the chassis via a slew bearing. Seating is coupled to the upper plate. The seating rotates with respect to the chassis via controlled rotation of the slew bearing with reference to the chassis. The seating can be rotated to point in any direction with respect to the chassis regardless of the direction the steerable propulsion wheels move the chassis.
