English Translation: Somatosensory Simulation Technologies of Triple-Screen Six-Axis Racing Simulator

The somatosensory simulation technologies of a triple-screen six-axis racing simulator mainly rely on the coordinated operation of a 6-DOF motion platform, triple-screen visual simulation, force feedback control, and multi-sensory special effects to accurately reproduce racing dynamics and G-force somatosensory perception.

1. 6-DOF (Six Degrees of Freedom) Motion Platform Technology
   As the core of somatosensory simulation, it adopts the Stewart parallel mechanism, driven by 6 servo electric cylinders to realize precise movement in six dimensions.
   Six Motion Dimensions
   Linear Translation
   Surge (X-axis): Forward and backward movement to simulate inertial impact during acceleration and braking.
   Sway (Y-axis): Left and right sliding to simulate sideslip and drifting.
   Heave (Z-axis): Vertical lifting and falling to simulate road bumps and kerb jolts.
   Rotational Attitude
   Pitch: Forward and backward tilting to simulate nose-lifting during acceleration and nose-diving during braking.
   Roll: Left and right tilting to simulate centrifugal force in high-speed cornering.
   Yaw: Horizontal rotation to simulate steering, tail sliding and collision rotation.
   Core Control Algorithms
   Inverse Kinematics Algorithm: Real-time calculation of the telescopic length of 6 electric cylinders to achieve the target attitude.
   G-Force Cueing Algorithm: Simulate continuous G-force in cornering and acceleration through tilting and short-distance movement within limited travel stroke.
   Filtering & Smoothing Algorithm: Filter high-frequency noise, retain key somatosensory feedback such as tire vibration and engine jitter, and prevent motion sickness.
   Low-latency Synchronization: Response time within 0.1s to ensure full synchronization of somatosensation, screen image and operation.
2. Triple-Screen Surround Visual Simulation Technology
   It delivers strong visual motion cues via ultra-wide field of view to deepen immersive experience coupled with somatosensory feedback.
   Seamless triple-screen splicing: 3×43/49-inch screens with 120°-180° ultra-wide FOV (Field of View), covering human peripheral vision.
   Frame synchronization & low latency: Triple-screen V-Sync with screen tearing less than 1 frame; video latency below 20ms.
   High dynamic rendering: 4K resolution, 120/144Hz high refresh rate and HDR, accurately presenting speed optical flow and track details.
3. Steering Force Feedback Technology
   Convert vehicle dynamic data into physical resistance and vibration to achieve integrated man-machine driving perception.
   Direct Drive Steering Wheel Force Feedback: Adopt direct drive servo motor (torque ≥20Nm) without reduction gearbox, delivering delicate feedback of road texture, tire slip and steering resistance.
   Pedal & Handbrake Simulation: Hydraulic/pneumatic brake pedals simulate progressive pressure and ABS jitter; accelerator travel feedback reproduces resistance changes with engine speed.
4. Multi-Sensory Linked Special Effects Technology
   Complement immersion with auditory, tactile and wind sensory simulation.
   Seat Vibration & Haptic Feedback: Built-in low-frequency vibrators to simulate engine roar, chassis resonance and collision impact.
   Surround Sound Effect: 5.1/7.1 channel or 3D spatial audio to precisely locate engine noise, wind noise and tire noise.
   Wind Resistance Simulation: Face/body fans automatically adjust wind speed according to driving speed and track environment (tunnel, rainy day, etc.).
5. Real-Time Data Interaction & Software Ecosystem
   Vehicle Dynamics Model: Run professional simulation software (Assetto Corsa, rFactor, CarSim, etc.) to solve vehicle status in real time.
   Data Transmission Protocol: Transmit telemetry data (speed, G-value, road condition) via UDP/TCP and Shared Memory.
   Driver & Calibration Software: Manufacturer SDK (e.g. SimTools) for data parsing, somatosensory intensity adjustment and motion travel limit setting.
   Core Objectives of Somatosensory Simulation
   Restore real G-force somatosensation of acceleration, braking and cornering inertia.
   Feed back road surface details to distinguish asphalt, gravel, kerbs and potholes clearly.
   Low dizziness and high stability with smooth motion and visual-motion synchronization, ensuring long-time comfortable experience.
   Full-link closed loop: Operation → Vehicle dynamics calculation → Motion/visual/audio feedback → Operation adjustment, realizing ultra-low delay closed-loop interaction.
