Hydraulic Motion Simulators

ACUTRONIC specialises in the development of 3-Axis and 5-Axis Motion Simulators designed to meet the challenging needs of HWIL Simulation of Radio Frequency (RF), Infra-Red (IR), Electro-Optical (EO), Laser and multi-mode missile systems, smart munitions, seekers and inertial systems. 

The high rate, acceleration and load demands of Hardware-in-the-Loop simulations in a time continuous environment are often unable to be satisfied with an all electrical Motion Simulator solution.  In these situations ACUTRONIC is able to provide solutions based on all hydraulically actuated axes or a hybrid solution where the inner (roll) axis is electrically driven and all other axes are hydraulic.

ACUTRONIC has extensive expertise in the design, development and implementation of hydraulic systems where the compact and efficient high torque actuators provide a significant torque to mass benefit when compared to similar sized electric motors.  This results in higher performance and more compact systems.

 The ’33 Series’ and ’55’ Series hydraulically actuated Motion Simulators are hosted by our de-facto industry standard ACUTROL®3000e digital controller equipped with Real Time Reflective Memory interfacing to help ensure a high speed, low latency, deterministic simulation environment.  The flexibility of the ACUTROL®3000e controller and the embedded control algorithms are ideally suited to resolve the resonances and system non-linearities present within hydraulic systems.

In addition to our Motion Simulators, ACUTRONIC has a proven track record in the provision of integrated HWIL System Solutions and can provide expert services ranging from HWIL advice and consultancy through to the provision of ‘turn-key’ HWIL Simulation facilities including the specification and supply of all associated sub-systems, communication architectures and building infra-structure.
