After many iterations to try to respect the above specifications, I will start with these dimensions:

3D rendering in top view, with the final dimensions of the motion simulator
Motion simulator final dimensions


With 620mm stroke actuators (against 500 before).

This gives in pure movements :

  • Pitch: +33.9°/-29.2°
  • Roll: -/+ 30.9°
  • Yaw: -/+ 41°: -/+ 41°
  • Heave : -380/+352mm
  • Sway : -/+ 480mm
  • Surge : -/+500mm

The aim is to have great possibilities to mix several movements at the same time and not to be at the end of the actuators .
