First build 3 or 4 DOF motion simulator

Hello,
First thanks for all the usefull information on this forum.

After a lot reading, watching, testing, programming (not real programming ) and collecting materials i am ready to start the build of a real Motion Simulator.

First tested on a scale model 3DOF (Roll, Pitch and Yaw) balancing on a balljoint using a Arduino Uno and some RC-servo's



The testproject was working fine but the Real Sim will be first 3DOF (R, P an S) with a option to 4 DOF (R, P, H and S), i think the Sway function is more usefull for racing and i like the optional Heave function for a more realistic VR experience.

For the simulator i use aluminium constrution profiles size 45x90mm and 45x45mm, motors and controll is still a big ? I have experience with all techniques (AC worm, frequency convertors, DC brushed/brushless, stepper, lineair etc. its all about price/performance/noise.

Some pics

Update soon, tomorrow start working on a solid joint

Stay healthy.

Planning for today, a solid joint.

This is a part from a old optical polisher i think it will do the job.



Job done, the whole centerjoint and sliding system is works smoothly without any play.
Until now i am very satisfied with the result, now it is waiting for a sports seat and some 24v DC wormgear motors for testing (only 35watt). Everything is rather delayed by the whole virus problem.

Stay healthy

Looks good Jan , i'll be watching your progress with interest.
(veel plezier met het bouwen )

Thanks #dedas i enjoy this project a lot

Today i run in to some geared AC motors, in my opinion the are strong enouch for a 3DOF with centerjoint, please shoot if iam wrong i have not purchased them yet

To continue with the rig design i am still waiting for the sportseat, it is lost for a week now

Stay healty

At least after a lot of changes, failures, smoking drivers, jittering motors, etc. we have movement........ ME VERRY HAPPY
Now try to get a licence to load more games.

@noorbeast Thanks for your reaction.

I think the responce is limited because the small range of the pots.
The situation is like this.
AC motors;
* 220 Watt
* 2800 RPM
* 32:1 wormgear



To reduce speed and add some power i add a 3:1 gearbox to the motor. The construction gives also strength and support to the wormgearbox (only 3 M6 bolds for the connection to the motor is not much).

The end result will be 29.17 RPM at 50Hz on the final axis.
The potensiometer (HQ 5K 10 turn) is connected to the axle of the wormgearbox.



A half rotation of the of the final axle results in 1.5 tuns of the pot, responce maybe not acurate enough?. I hope there is a way to change the range of the pots in the SMC3 program.


Sorry for the wiring (prototyping phase but technical safe)


First some playing with the rig and later on with the settings.

Regards, Jan

i need more photo ,especially Close shot。i want to built one recently
