Dynisma Motion Generators (DMG) are the most dynamic, responsive and scalable driving simulators in the world

DMG® delivers maximum bandwidth with minimum latency by co-designing software and mechanical engineering, and by removing every possible obstacle between the driver and the data. It’s the future of accelerated, efficient, vehicle development.

EXPLORE DMG

 

BENEFIT OF HIGH BANDWIDTH

​​​​​​Greater bandwidth is a core focus of the DMG® philosophy.

High bandwidth facilitates motion cueing not possible on conventional motion platforms. A real driving experience contains information at frequencies far greater than 60Hz, including road noise, engine vibration, ABS vibration and high fidelity vehicle dynamics feedback.

The human body is very sensitive to small changes – by accurately transferring this information to the driver, DMG can provide a far more realistic and immersive driving experience.

 

BENEFIT OF LOW LATENCY

With latency as low as 3-4ms, DMG® can deliver prompt vehicle dynamics feedback. This means the driver can react faster to events such as oversteer and means that visual stimuli such as kerb strikes are provided faster than even 240Hz projectors are able to update.

 

DIRECT DRIVE

Motion cueing data goes straight to the driver’s vestibular system in the rawest possible form, giving them an immediate and immersive sensory experience.

By minimising friction and eliminating backlash, our Motion Generators are able to accurately reproduce the smallest and most sublte of cues.  The resulting drive experience is extremely clean, precise and natural, representing a step change in immersion and accuracy of driving simulation.

 

BENEFIT OF FEED FORWARD

Traditional motion generators rely heavily on feedback which by its very nature, has inherent delay.

Thanks to Direct Drive actuation and accurate multibody models, DMG removes all obstacles by working almost entirely on feed forward – the controller does not wait for feedback but supplies DMG with data on the environment immediately.

Feed forward enables DMG to transmit information in the rawest possible form direct to the driver’s vestibular system.

 

CARBON COMPOSITE STRUCTURES

With superb stiffness, strength and low weight, carbon composite structures help realise the maximum bandwidth and acceleration potential of DMG. 

Through in house capabilities and our partners, Dynisma has full lifecycle capability for composite components, design, verification, manufacture, validation, transport, storage, maintenance and inspection.

Dynisma makes extensive use of composites in the development of its Dynisma Motion Generators and the development of custom payloads for its customers.

 

SIMULATION, DESIGN AND ANALYSIS

From full system multi-body modelling right through to subsystem stress analysis, simulation and optimisation form the backbone of the development process of DMG systems. 

MathWorks and Dymola toolsets are drawn upon early, to inform design decisions, and later, to develop and test control algorithms in the safety of simulation. Dynisma Motion Generators are designed in Siemens CAD packages, employing the full Altair suite to target world leading bandwidth long before confirming it in comprehensive real-world testing programmes
