Motion Simulation Hexapods

Motion simulation hexapods are used for high frequency motion replication and disturbance generation. Our systems use voice coil actuators to provide large accelerations and high bandwidths. The HX-M300 and HX-M350 have similar designs and architectures. The HX-M300 is more compact while the HX-M350 can accommodate larger payloads. Custom control system tuning can be used to address unique requirements.




  • Hardware-in-the-loop simulation
  • Missile tracker simulation
  • Simultaneous multi-axis vibration testing
  • Disturbance simulation for cryocoolers, stepper motors, etc.
  • Fatigue testing

1. The ranges of motion of the six axes are interdependent. Listed values represent the maximum range with all other axes at their zero positions and the center of rotation at the center of the payload interface.

2. Closed-loop bandwidth depends on the axis and payload mass.
