SFX simulator surge or sway module
How Surge (Forward/Backward) and Sway (Left/Right) are Achieved
In most motion platforms, especially those using 4 or 6 linear actuators (like the SFX-100/150 or Qubic System platforms), surge and sway are often achieved through a combination of pitch/roll movements and heave (vertical movement).
Surge (Forward/Backward):
A sudden acceleration (forward surge) is typically simulated by tilting the platform backward (pitching up). This creates the feeling of being pushed back into your seat due to gravity.
Braking (backward surge) is simulated by tilting the platform forward (pitching down), giving the sensation of being thrown forward.
Sway (Left/Right):
Turning left or right, or experiencing lateral G-forces, is simulated by tilting the platform left or right (rolling). This makes you feel the lateral forces of cornering.
While some advanced 6-DOF (Degrees of Freedom) platforms can achieve pure translational surge and sway, most consumer and prosumer platforms use these rotational movements to "trick" your inner ear and effectively simulate the sensations.
