Dynamic Motion Seat for Simulators - Visit the ACME Dynamic Motion Seat Product Site

The ACME Dynamic Motion Seat (DMS) is a cost effective method of providing motion cues to a pilot or other vehicle operator. The dynamic seat adds inertial cues experienced in the operational system, whether its an aircraft, ground vehicle or other platform. Motion cues enhance the immersive experience of simulation, enabling better training and operator experience.

The value of motion is recognized and accepted in commercial aviation, in fact the FAA requires motion in it’s certified flight simulators. The military widely uses motion across a spectrum of training systems, including helicopters, fixed wing aircraft, and ground vehicles.

The Dynamic Motion Seat delivers state-of-the-art performance providing vibration and motion cues in five independent axes of control, it uses three directions of movement - vertical, longitudinal, and lateral plus a has differential surge that combines with sway motion to replicate roll.

Independent vertical motion is applied to both the seat bucket and the seat pan in a sequence called squab motion.  Vertical motions are used together to provide realistic G-cueing.  Raising the pan and lowering the bucket provides a sensation of sustained positive G-force to the crewmember.  This is achieved by increasing the vertical force on the crewmember, easing the lap belt tension, and slightly lowering the eye position. Reversing these motions provides the sensation of sustained negative G-force.

Longitudinal and lateral independent motions are applied to the seat back.  Longitudinal motion or surge, provides onset and sustained cues of increasing or decreasing speed.  Lateral motion or sway, provides side pressure cues for lateral acceleration.  Combining lateral and longitudinal motions replicates roll and pitch accelerations.

ACME’s DMS uses a sound transducer in the seat pan to provide high-frequency vibrations for additional tactile cueing.  These vibrations when combined with the various accelerations can create special effect cues, such as:

• Touchdown bump, runway rumble, runway expansion joint bumps, or tire problems
• Helicopter rotor malfunctions such as main rotor out of track, out of balance, or delaminating
• G-Effects
• Airborne equipment and gunfire vibrations, weapons fly out
• Obstruction impacts
• Wheel and road vibrations, turning cues, engine hesitations
• Water and wave effects, dock bumping and humping effects

ACME’s Dynamic Motion Seat is self-contained and can be mounted on existing mounting points, it contains a full set of safety features, and is designed for maintainability, sustainability and a long life-cycle.  The DMS offers a low-cost, state-of-the-art solution to providing motion realism to almost any kind of vehicle simulation.
