Our EVOLVE 6DOF motion platform has been successfully integrated and tested with the advanced COSIN Scientific Software FTire (Flexible Tire Model) – one of the most precise real-time tire models used in professional vehicle dynamics simulation.
This cooperation confirms that EVOLVE is not only a high-end motorsport simulator, but also a fully capable engineering-grade motion system for tire, chassis and steering development.
What Is FTire and Why It Matters
FTire (Flexible Tire Model) is an ultra-detailed physical tire model that simulates:
-
tire carcass flexibility
-
tread deformation
-
contact patch behavior
-
transient force generation
-
road surface interaction in high resolution
Unlike simplified tire models, FTire calculates tire-road interaction in real time with high numerical accuracy. This makes it suitable for:
-
vehicle dynamics development
-
NVH and ride comfort studies
-
steering system validation
-
driver-in-the-loop simulation
When combined with a true 6 degrees of freedom (6DOF) motion platform, the simulation environment becomes physically convincing and biomechanically meaningful for the driver.
Why 6DOF Is Critical for Tire and Steering Validation
A tire model like FTire generates highly detailed force data.
However, without proper motion reproduction, the human driver cannot correctly perceive those forces.
EVOLVE platform reproduces all six axes of vehicle motion:
-
Surge (longitudinal acceleration / braking forces)
-
Sway (lateral cornering loads)
-
Heave (vertical dynamics, surface inputs)
-
Roll (body roll behavior)
-
Pitch (brake dive / acceleration squat)
-
Yaw (rotational slip behavior)
Our electric actuators (500 mm/s speed, 350 mm stroke)

ensure dynamic response fast enough to match high-frequency tire events generated by FTire.
This is essential for:
-
steering feel realism
-
slip angle perception
-
micro-corrections during limit handling
-
evaluation of transient maneuvers
Without full 6DOF motion, subjective steering feedback becomes incomplete.
Steer-by-Wire and Steering Feel Testing
One of the most important applications of the EVOLVE + FTire setup is steer-by-wire validation.
Modern steering systems increasingly rely on electronic control without direct mechanical connection. This makes driver perception testing crucial.
Using EVOLVE 6DOF, engineers can:
-
evaluate steering torque mapping
-
test artificial steering feedback curves
-
simulate parking maneuvers and low-speed steering effort
-
validate on-center precision and dynamic response
-
compare different steering tuning strategies in a controlled environment
Because the driver is physically exposed to correct acceleration cues, the subjective evaluation (human factor analysis) becomes significantly more reliable.
Driver-in-the-Loop Engineering Tool
EVOLVE 6DOF transforms simulation into a driver-in-the-loop development platform.
Applications include:
-
ride comfort evaluation
-
chassis balance tuning
-
limit-handling studies
-
emergency maneuver validation
-
ADAS steering control system testing
-
parking assist development
-
stability system calibration
The recommended workspace is 300 x 300 x 250 cm with standard 230V 16A power supply

From Motorsport Simulation to Engineering Validation
Originally developed to deliver factory-level simulator quality, EVOLVE 6DOF is based on the same architectural principle used in professional motorsport simulators – a six-actuator Stewart-type motion configuration

.
With FTire integration, the system extends beyond performance training into:
-
tire model validation
-
chassis development support
-
steering system engineering
-
advanced vehicle dynamics research
This positions EVOLVE not as a consumer simulator, but as a compact, high-performance engineering motion platform suitable for OEMs, Tier-1 suppliers and research institutions.
Conclusion
The combination of:
-
FTire’s high-fidelity tire physics
-
real-time telemetry conversion
-
full 6DOF motion reproduction
-
high-speed electric actuators
creates a realistic and analytically valuable simulation environment.
EVOLVE 6DOF is more than a simulator.
It is a precision motion tool for modern vehicle development.
