simulateur 3 dof heave, motor 350w 24V

C'est original et bien pensé de compter sur la non-déformation des U pour faire en sorte que la plateforme soit stable
Quel jeu y a t-il pour la plateforme supérieure quand tu la secoues ?

S'il y en a trop, il faudrait renforcer la rigidité en torsion latérale en évitant des rotules et en élargissant les appuis


Good idea to use U shape lever in order to stabilize the plateform!
How big is the gap when you shake the upper plateform?

@Nick Moxley I had the opportunity to try his first g-seat with the same principle and for me this is by far the best feeling of acceleration/braking that I could feel on a simulator. You feel like aspirated by the seat or you crush on the harness, and yes it can help for a better driving.

le très léger jeu est due à la rotule, mais pour le voir il faut que le plateau effectue un mouvement de rotation
the very slight gap is of the ball joint, but to view it is necessary that the plate performs a rotational movement

j'ai utilisé une roulette pour pousser la palette dorsale, ce qui est plus facile
I used a roller to push back pallet, which is easier

1 profilé de mur pour radiateur et 1 profilé d'étagère assemblé entre eux
1 wall profile for and1 radiator shelf profiled assembled them

j'ai fait les réglages avec l'aide de simtools et l'effet surge
I made the adjustments with the help of simtools and surge effect

quand le plateau mobile recule (accélération) les palettes dorsale avance et écrase le dos sur les cotés
when the movable plate back (acceleration) the advance back and crushed pallets back on the sides

quand le plateau mobile avance (freinage) les palettes dorsale recule on ne ressent plus de pression dans le dos
when the movable tray advance (braking) the dorsal pallets back you do not feel more pressure in the back

je dois encore fabriquer le système pour la palette dorsale gauche, ensuite je pourrais montrer une vidéo en fonctionnement
I still have to make the system back to the left palette, then I could show a video in operation

did you have any problem about parallelism for the surge mecanism?

tu n'as pas eu des difficultés pour obtenir le bon parallélisme des glissières surge ?
moi j'avais galéré pour mon essai de dossier glissant même avec des trous oblongs
ça coinçait même sur la faible course...

Non aucun soucis, mais j ai fixé d abord les rails parallèlement, placé les roulement linéaire, posé la plaque pour repérer les trous de fixation et percer.
Bon j ai du corriger deux trous sinon après ca été.

No worries either , but I have Fixed Abord of parallel rails , place the linear bearing , raises the plate pour locate the fixing holes and drill .
Well I have the Correct Two holes after ca otherwise been .

premier test avec le replay de RRE, le ressentit dans le dos est bon

I really love this design. I'm not finished my gseat yet and I am already trying to think of ways to mount it on a moving platform. Due to its steel construction I fear it will be too heavy though. You have some very innovative ideas. Please share more videos of the seat in action. I'd like to see the entire setup. Is it seat mover only?

I have two spare 24v 360w (41.5Nm) 30rpm motors here. If I bought a third I could maybe create a similar 3dof. Do you know the total weight you are lifting?

salut, je travaille beaucoup, cette semaine je suis en congé, je pourrais peser le poids et te mettre une vidéo en fonctionnement

hi, I work a lot, this week I am on leave, I could weigh the weight and put you in a video operation

Hi，I planned to build 6 DOF DC motor based sim, how much rated torque do I need consider for each motor?
the platform and player are 120KG.

@Racing Mike : all depends on the amplitude of movements, your budget and the efficiency of your system. But I think 20-25Nm is a minimum for a full mobile.
@zigzag49 built a 6 DOF seat mover with 6 smolka 16Nm and using a spring.

below is my calculation, could you help to check if my understand is right or not, thanks.

1. In the FAQ #89, the Linear Velocity is recommended between 150-700mm/s, usually I play racing game like Project Cars, AC, how fast should I choose? The speed is determined by motor RPM and CTC length, what value(CTC, RPM) is recommended? The CTC could be changed later, but the RPM is fixed, if I buy the wrong motor, no chance and time to change.
2. Motor power and torque.

Let’s supposed Linear Velocity is 500mm/s, platform and player weigh 120KG, according to FAQ #89, need 60N(120kg * 0.5m/s) force, and need 120kg*9.8N per KG to counteract gravity, totally need 1236N. I calculated in below website, totally required 98Nm.



If doesn’t consider efficiency loss, each motor should provide 16Nm, consider the efficiency loss, how much motor torque should prepare? (I’M NOT SURE IF I CALCULATE RIGHT OR NOT)
As I checked online, 350W DC motor with RPM 60 can output about 25Nm, I don't know it's too much or not engouh.

La construction de notre ami Willaupuis : Trois moteurs de 350w a 60 RPM acceptent verticalement plus de 150 kg sur une course d'environ 120mm à près de 1m/s.
Donc construire un 6DOF avec de tels moteurs ne doit pas créer de soucis particuliers si les mouvements sont d'amplitude compatible avec la force disponible.

The construction of our friend Willaupuis: Three motors 350w 60 RPM accept vertically over 150 kg over a stroke of about 120mm to nearly 1m / s.
So build a 6DOF with such engines should not create particular concern if the movements are amplitude compatible with the available force.

Thank you very much, your information is very helpful for me to choose motor.

@willaupuis Hi, can you share your motor specification and load information for my reference? thanks in advance.

Hi, could you share the shop link you bought the motor?

24V 350W 60 RPM motor I found only can output 25 torque.

We bought these motors. You can ask for a special shaft if you want.
You can see the datasheet, they are 45Nm

Thanks. How about the motor noise?
I checked they supply up to 500W motor, do you think how much Watt should I buy for 6dof?
And how much is your order shipping? Is it very expensive from China?

No noise, we ask for a plastic gear to lower the noise.
I think for 6 dof the 350w will be enough, but more power is never useless You need to find an appropriate psu, and this is expensive

Motors are 100$ and shipping depends on the weight (5kg each) and probably the country.. Don't forget there are customs fees. You can estimate a total price of 180~200$.
