3DOF power simulator

ok it works

[thecure]

I found this h-bridge ... I do not understand how work back and forth ( there isn't a dir )...only two pwm

I've a problem with rfactor, for example, when I crash into the wall or the guardrail the motor's rotation drastically ralentate and then when I come back in the circuit the problem does not solve. Is there any parameter to fill in x-sim?Thank you

Hello there,

Any progress on the actuators?
I am starting a very similar project and was hesitating between using gearboxed motors, or linear actuators like you were thinking.
Thank you.

he would need powerful actuators, unless he makes a spring underneath. I got my hands on some actuators that are ETH series ,
ET050B05MA000A00FMDH0100A but I use 12v motors, if you can find them cheaper than $2700 each , these would be the go for sure. Mine move 40kg at 300mm per second with 12v motors viewtopic.php?t=605
SCN6 may do but they are costly as well.

Checked your link and it is quite impressive.
I am trying to get the same type of motion, but I think that I am going for a gearbox motor setup.
Maybe I should ask my own thread here.
I have gotten more feedback here than on the other popular sim forum (Hear, nothing at all from the other side... )

Hello guys,
Sorry for our absence, but between work
and various tests and measurements and drawings we arrived at the final
we're almost there, we are now waiting for the material from England
to transform the pneumatic cylinders in electric actuators ...
similar to those found on line, but a bit more cheaply
and with the size we are interested ...
at the beginning we wanted to redo all 3 actuators from scratch,
then a bit on the forum, a little online, stealing here and we said:
dismantle the cylinders that would otherwise become obsolete
and them "fill" with the mechanics for moving ...
I'll post a small drawing to understand.
I hope you like it and see you soon

Looking really good!

What speed are you trying to get for the actuator?
And what speed would be sufficient?

I found some Chinese ballscrews maybe this is something for you:
(I don't know much mm motion there is in 1 revolution?)

They look ok, maybe just some fast motors on them, perhaps 4000rpm or faster.
For actuator speed, the preferred is minimum 150mm per second, depending on configuration.
Meaning if you have a BIG throw, you need faster.
