estanislaolopez 2dof simulator with wiper motors Argentina

Hello to all members of xsim:
Some time ago I've been watching the forum, come here trying to build a simulator with motion and after several months I'm getting ...
First built the AMC 1.5 and Tronicgr H bridge, and then modify the structure of my cockpit, there is nothing new, just use your ideas for doing something Simforce gt style ...
Since my English is bad (use Traslator) I show you some pictures
AMC 1.5, H bridge and Power supply with old pc cabinet:

I use a rectifier of a car alternator to the power supply...

The structure of the cockpit, I still need to finish some details ... (get a better seat :lol: ...)



A video of the first tests, after I had some problems with the bridge H :thbd:

Greetings and I'll post more news ...

Re: My 2dof simulator with wiper motors

hey looks great!

what have you for a travo you used?

Re: My 2dof simulator with wiper motors

Hi, I understand that you refer to the transformer of the power supply, is 12V 300VA, bridge rectifier is recycled from a car alternator and filtering is performed by 8 capacitors of 4700 uF ...

Re: My 2dof simulator with wiper motors

is it enough if I do it with the transformer?

( 2x wiper motor 12V and 40W )

thanks

Re: My 2dof simulator with wiper motors

Hello xsim community
After a long time to achieve the H-bridge repair and operate the simulator :yippiee:
There was a PCB track cut into the gate of one of the IRLZ, then stayed with continuity D and S ...
Create a simple profile to start with effect longitudinal, lateral and vertical, should I study to get better usage xsim
I'm posting a video to see the first test, then I need to paint and upholster the seat or get a new

Re: My 2dof simulator with wiper motors

Congrats! :thbup:

So far it seems to me that longitudinal g-forces (accell/brake) are missing.

Regards

Re: My 2dof simulator with wiper motors

Hi Ego,
I can not still play these forces (accell/brake).
I do not understand very well the xsim, I will continue investigating the software

Regards

Re: My 2dof simulator with wiper motors

Post your .rn2 savefile (just Math dialog tables...), so we can have a look why there are no accell/brake effects played.
I guess you may have forgotten to uncheck the auto max detection checkbox.

Did you already try one of the motion profiles available here in the forum?

Re: My 2dof simulator with wiper motors

Thanks Ego, I think I had a profile fails, repeat the longitudinal effect in the two axes, now lateral effect in axis 1 and longitudinal effect in axis 2 is noticeable acceleration and braking. When in my house to post the profile you see it, is very basic ...
But I have a problem with one of the wiper motors, does not respond with the same speed as the other (the two engines are of the same make and model), the left responds very well, brusque at times, very soft right, then to accelerate when the two together should raise the seat is tilted to the right until the end of the slower travel ...
Will review the wipermotor and also the H-bridge ...
I hope you understand me, my English is very bad ....

Re: My 2dof simulator with wiper motors

It is normal that wiper motors turn faster in one direction, than to the other. You should turn arround one motor, so that speeds are equal.
Preferrably, the faster/stronger direction should point to forward/braking, while the slower direction should go backwards/accelleration.

There is a speed fix for wiper motors tough...but I dont know if the effort is worth the result.

Re: My 2dof simulator with wiper motors

I do not think I expressed correctly, I did not mean the motor rotation (left or right) but to the left side wiper motor simulator that works very well, and wiper motor on the right side of the simulator runs slower and with less acceleration, then in acceleration when the two engines are positioned with the arm down one of them makes it faster than the other and not achieved the desired effect ...
Not if the problem is in the engine or on the bridge h ?
Sorry if I do not write correctly

Greetings

Re: My 2dof simulator with wiper motors

how did you set your pots? I turn more and more groups. 2 are already broken pots

i cant calibrait in the profiler... when i calibrate my pots turn and turn... 360

(i use 270 potis)

Re: My 2dof simulator with wiper motors

Well, if the problem is caused by the h-bridge, you could check this easily by swapping the cables M1<=>M2.

Some wiper motors have two + cables, for slow or fast speed.

Are both motors the same brand?

Are your power supplies delivering enough Ampère and equal Voltage? Are they the same brand? Swap power supplies to check!

If you can rule out the points above, one motor might be damaged.

Regards

Re: My 2dof simulator with wiper motors

The engines are of the same make and model and are placed both on the slower speed,
The power supply is 12V 25A, and the engines consume about 4.5 amp.
Tomorrow try to change the connection of the motors to rule out a problem on the bridge h

Regards

Re: My 2dof simulator with wiper motors

Hi Interview, the calibration of the pots, made with the AMC multiturn preset, turn the preset you give the grades you need to run the pot, that I did and then connect the wiper motors
I am using 120 ° of travel of the pot

Regards

Have you solved the ballance issue with the wiper motors?

Have if I understand, I think you mean the balance of the structure ... is balanced with a person sitting on the chair, with the threads of the chair with arms that connect motor regulates the balance point, so is best used wiper motor

Sorry if I do not understand English well ...

Re: My 2dof simulator with wiper motors

Hi Lopez,
That is what i mean with balance. Have you solved the problem with the motor unbalanced responses?

regards

Ahhh! sorry I had not understood, the problem was in the H-bridge, to work on an engine with more acceleration than the other, now I'm working on a new H-bridge, when I finish I will put the news ...

Regards

Greetings to all
After some time off work in the simulator came back, put a new seat and built a new bridge H, is an N channel mosfet design, these are the results, although I still need to understand a little more the x-sim, need a little more reaction in the wipermotors

Any suggestions are welcome
