D-Box or not to D-Box

About D-Box

I did not find any online store to buy D-Box.
Should be contacted to buy?

I dont think there is a video, even I had a search

I am not alone in wanting to see it in action

Ok, did a quick search, no SCN videos of them, but AC motor videos, slow as motion

Thank you for the videos!

The screens of the second video simulator moves dangerously

oh my the monitor wobble is horrible in that 2nd one, Motion looks rather......dull.

Yeah, the designs used for both rigs in the videos look unstable resulting in a lot of unwanted platform wobble.

VR for more "full time gaming" perhaps yes.
Casual gamers, like me, screen in front.

Very impressive indeed. Cutoff Freq at 100Hz makes sense since most sim feeds rate at 10ms. Surely, will make chassis move more realistic. Attached is chart of four corners ride heights movement from rF2 Corvetter GT2 car at Silverston. But for the price, well still too much for me. I am trying SCN6 40kgf (88 lb) ones.

That forum link didn't work, but this did

The D-Box design concept is perhaps unique

Contrary to many commercial and industrial motion systems where motion is controlled by discrete positioning commands, in D-Box’s Odyssee and Quest systems the motion signal is represented as a steady stream of position samples. In this sense motion is transmitted and processed much like a digital audio signal. There is no real distinction between motion and vibration. Vibration is simply what happens at the upper end of the frequency spectrum, while motion is what happens at the lower end.

The frequency response of an actuator must be flat from 0Hz to 100Hz, entering largely into the audio spectrum. To be able to achieve this level of performance, the motors that are at the heart of an actuator must be able to accelerate the passengers at accelerations of up to 1g, while at the same time supporting the full weight of the passengers and seats. At the other end of the dynamic range, motion must be so smooth that it is almost imperceptible​

I find the end result to be the D-Box motion is similar to the OSW FFB with a Kollmorgen+Simucube.

Through your seat, the D-Box provides road/surface texture. You can feel the concrete is you speed through the pit boxes, or tarmac to concrete to tarmac, the repaired patches and curbs of Sebring. You can feel the suspension and loss of acceleration as you shift up through the gears.

On the other hand Simvibe Extensions mode and presumably Gamevibe are playing specific effects through the shakers for shifter/pedals and seat.

Whether Simvibe/Gamevibe use canned effects for curbs, traction loss, engine RPM and gear shifts I do not know.

Nor whether Simtools calculates and outputs the same "vibration" through the actuators that D-Box does.

Thank you for the reply.

Does Gamevibe reproduce a range of vibration (Hz range) that Simtools filters?

Does Simtools play engine RPM, traction and surface texture with 4 actuators (heave, pitch, roll) ?

So for chassis vibration modes the SimTool 6dof motion scheme does not cover, does it? One has to go with transducers with "Game vibe" if one wants to feel vibrations, right?
Also, I wonder how the SimTool simulates the vertical g force effect.
thanks for your reply.

does currently SimTools heave implementation actually include chassis vibration modes?
I know SimTool outputs "vibration", but I am not sure if this is purely due to g-effects as SimTool calculates for 6d0f movements or actually includes the chassis vibrations modes. Vibration can be either vertical (linear along the Z) or/and 2D....check the chassis four corners' ride heights.. you will see roll/pitch shall be oscillating too.

Edit: the reason I asked is that both D-Box and SimX SW having an option allowing to add vibration (D-Box) and Vertical-g (SimX commander SW).
