Gimbal design

Gimbal design - 12/10/11 01:06 PM

Hi pit builders,

I would like to show the gimbal layout I am currently working on.
I use the principle of the real aircrafts "feel and centering unit". Ball bearings are rolling on CAM plates (one for each axis) as the stick is moved. The CAMs forcing the bearing holder arms up and down. These arms lifting the extension springs.

The good thing is, that with different profiled CAMs I can produce different stick characteristics.

I will also use rotational fluid dampers (one for each axis) which will damp the movement of the stick to get a nice smooth realistic feeling.

Wow, very impressive. Are you planning it as a deskmount, or a full-sized floor mounted stick?
You've probably got some alternate cam designs already, but I would suggest one with an arc, rather than a V to reduce/eliminate the center detent feel. IJ and his NXT has spoiled me and probably many others in that regard. wink
Looking forward to seeing a prototype.

Re: Gimbal design - 12/11/11 09:20 AM

Hi 9T,

thx for your input. The gimbal is designed for a full scale control column. As you said, the round CAM shape is very important. The CAM is not V but more like an "U" to eleminate the center detent. The radius at the bottom is quite critical. If it is too big, then the movement can be very floppy around the center. The good thing is that it is easy to make different CAM shapes for experimenting. I don`t know if this design will ever get into manufacturing, at the moment it is more like an experiment. will see..

I made a short video about the CAM movement.

MMmaister,

Good job, you are in right way.

Bauer (avi-sim.ru) use similar concept in your devices.
He say that changing the CAM profile you get different centering feel.

BTW - Accord him, the way to get acceptably cost in manufacturing process is use laser cut metal, instead milling, machining...

Re: Gimbal design - 12/11/11 04:58 PM

Hi Sokol,

Baur`s work is truly amazing. He uses the sheet metal very creatively for sure. As I can see his CAM shape is similar to mine, and that is a good sign for me:)
I will finish up the design keeping in mind the goal of simple and cheap machining. I still have a long way to go. I have done any calculations neither on the resulting stick forces or on construction strength. I will do this, then I can optimize the design. After all I will ask for some quotations and then I will see the price of dreaming... CNC is never cheap when you make one single piece.

That is how it looks like today:

Let me know when you get ready to get some prices. I know several different CNC machine companies around my area of the world that I used to deal with that would love to be able to at least quote the project.
Posted By: VO101MMaister

Re: Gimbal design - 12/17/11 11:25 PM

Thank you for the offer Reschke.

Currently I am fine tuning the CAM, to have a linear spring extension. Also I am compressing the design to have a more compact size. I am close to the goal, but some more detailed stick force calculation and strength calculation is required.

Great job VO101MMAISTER.Looks very promising. Can't wait to see the conclusion thumbsup
Posted By: VO101MMaister

Re: Gimbal design - 01/03/12 10:57 AM

Thanks Propman!

I have done some more calculation.
Due to the long stick, de gear ratio is quite big. It is ca. 1:18
It means that with the usage of 630N springs, the resulting max. stick force will be 35N what is equal to ca 3,5kg.
It sounds like a comfortable stick force, however I could live with a bit more, especially on the elevator side. I will have a look on this.

On the strength side I have a lot of reserve, so I can have stronger springs and I can change a few part to aluminium instead of steel.
Posted By: VO101MMaister

Re: Gimbal design - 01/03/12 06:52 PM

I tried the stick force on my current cougar setup. It is around 2,4kg and I found it pretty strong in a long dogfight. Therefore I can live with the 3,5 kg. So I am finishing the design and begin the super boring drafting.

In the meanwhile I wanna show some cool stuff I bought for this project on E-bay.
These are high quality industrial rotary viscous dampers. They are damping the rotational movements with the help of silicone oil. They provide +/- 40deg super smooth and !adjustable! damping for both axis. The street price of these gems is 580 USD/piece, so it was a bargain for 20USD each considering that they are brand new. I quickly bought 8 pieces:)

Re: Gimbal design - 01/09/12 12:19 AM

500 would be my guestimate, but that's without the sensors and might depend on the metal used. [EDIT] That'd be 3800 NOK

Re: Gimbal design - 01/09/12 02:30 PM

Yep, I think your guess can be quite accurate. I hope the small, family style CNC workshop I have contact with will quote good prices.

The pedal design is coming now. I have some ideas. It is just bloody hard to stand up from the CAD program at work and sit down with the same thing at home:)

Re: Gimbal design - 05/12/12 10:20 AM

A small update for this as well.

This design is also ready for machining, but before that I had to make some adjustments.
I decided to turn the whole gimbal system up side down. So the center of the gimbal can be as close as possible to the mounting plate, while I can use longer springs, and higher mechanism. It is important to keep the center close to the plate, otherwise I can end up with a huuuuge opening on it:)
I installed longer springs, so I can have some more pretension on them. Just like on the pedals I decided to use a simple steel mounting plate. The opening will be covered with leather boot.

Machinging is starting in June:)

The limiting is done within the gimbal. The CAM plate movement is limited by two screw heads. The round cut out is pure cosmetic, the stick won`t contact with it and will have square boundaries.

Re: Gimbal design - 07/16/12 08:34 PM

OK, here is some progress. I fully assembled the mechanism of the gimbal. It is basically finished, but I need to shorten some spring consoles. The column got its leather boot in beautifull Porsche Cayenne internal colour:) And finally I monted its crown jewell, the KG13 grip:)

The mechanism works perfectly as far as I could test it. Probably I will make a new CAM profile to create a more progressive control load character and to have a soft, mushy center feeling. The current one is just too noticable for my taste.

Some pictures:)

Posted By: Bluedeath

Re: Gimbal design - 07/18/12 12:19 PM

you need 3 wires for each pot like is explained on Leo's site image and since you just need 4 buttons you can connetc the button matrix pins to ground (with the switch in the middle of course)

I will use AMR (magnetic resistance) sensors, made by a guy in Ukraine. They are supposed to be even better than the halls.

Re: Gimbal design - 07/19/12 03:02 PM

If i may suggest a very minor change, turn the leather boot inside-out and fit it upside-down on the control column, fix it with a zip tie and then turn it back outside-in before fixing it to the base. That way it will look a little more polished and keep a little more dust out.

Re: Gimbal design - 07/21/12 06:07 PM

Well, I could not resist and quickly installed the sensors and took the stick for a quick spin within CloD. Well the stick was laying on my knees, so it was far from optimal, but maaan it is sweet!:) With the long stick, the precision sensors and the smooth hydraulic damping it feels awsome. I can`t wait to be finnished and test it properly.

If i remember correctly Leo Bodnar (don't kill me if is not him) done some experiment the real problem in the end turned out to be the software programming ,and the fact that is not possible to send different FFB signals in windows but all the peripherials will receive all the signals (or something like that)
Posted By: VO101MMaister

Re: Gimbal design - 07/23/12 03:45 PM

Well I am only using common sense, but is there any problem with using an existing controller+driver from an ffb joystick (MS ffb2) and attach stronger motors to it? Theorically some signal amplification could do the job. Mechanically only a right gearing is needed to put out the right deflection to the stick.

Anyway it is all just thinking for me. I don`t plan to start a new build in the near future. I will be glad enough if I can finally finish this one smile

Yeah, that should work (in theory smile ). Played with the same scenario in my mind, but with the original Wingman Force.

The nice thing about the FFB signal reaching all controllers; for a P-38 yoke I could attach the X
-axis motor from the Wingman to the Y-axis output (reversed) for a kind of push-pull setup on the Y-axis (ignoring the X-axis). The wheel of a Wingman Racing Force (converted to yoke) will handle the Y-axis.

In your situation, you could have two Sidewinders, reversing polarity on one of the sticks' motors and create a push-pull configuration on both axes. Double the forces. biggrin

Re: Gimbal design - 09/03/12 03:30 PM

Hi Chaps,

as I described in the Pedal`s thread, the testing is delayed due to the lack of space and testbed, but it will change soon. Meanwhile I got my new reshaped CAM profiles for the stick.

Now I am pretty happy. I have 0 center feeling. On the first few inches there is only the damper`s resistance, and a very slight centering force. Literally the stick stays where I leave it. Then the centering forces build up exponentially, supplemented by a very smooth and strong damping. Maybe I will try a bit weaker spring on the aileron side. All in all it is pretty close to what I am used to in a real aircraft.

wow.. amazing work!!!!!
i hope to show off my finished product come january.

i think i have 2-3 weeks till i finish my cyclics, then i will proceed to build torque pedals..

by the way, im not sure if your devices are stand along.. AVOID having all the units (pedal, joystick throttle/collective) stuck together in one platform...

my previous build was a platform. it sucked taking it apart.
i am making my setup modular... including the seat where if i didnt have no controllers connected, i can still enjoy sitting in the chair by itself..

your stick.. looks effin amazing. only con i have about your set up, is that your stick is way to far from the chair.. 3-4+ hours of flying, your arm will get tired from extension.
(i could be wrong in which you have referenced actual cockpit designs)

in my helicopter setup, im trying to put my joystick a few inches from my crotch...

but pit building is trial and error... wink

Re: Gimbal design - 10/21/13 12:58 AM

i was reasearching youtube for stick placement...

i recommend you to move the stick up towards your crotch to end up between your knees..





DONT MAKE THE SAME MISTAKE I DID..

Hey Hannibal! Don`t worry, the stick is right between my knees!:)

Nicely done MMaister. Very tidy

Re: Gimbal design - 10/23/13 09:59 PM

alright.
in my setup, my joystick would be next to my crotch in pulled back position, in my thigh before my knees when centered, and between my knees when the joystick is full forward.. (im setting my stick to have a 6" +/- deflection)

I think that is pretty confy setup, and very similar to the modern helicopter and sport aircraft layouts. I am flying motor gliders and the stick is placed pretty much where you described.

My control stick is placed a bit further forward because of the limitation of the seat I use.
I could use a bent column of course, but the current config is quite ok. It is also very similar to the common ww2 era warbird layout.

i was actually looking for that photo!

i saw that photo in the eagle dynamics / DCS forums a few months ago, but was unable to find it again.
my search came up with fa-18 seat dimensions

it didnt help me much, im pretty much going by trial and error to see what height and seat angle to make my seat base.
i hope to start my seats in 2-3 weeks!

Emailing on a quote... I assume I will need to sell one of my arms to afford those!

Thanks for the info!

Perhaps you can adapt a steering stabilizer from a bike. Not that is going to be any cheaper, really.

Re: Gimbal design - 11/17/16 06:05 PM

Wow, this is a really nice looking piece of kit!

I know it has been several years since this thread has been touched but what can I say, I'm really impressed.

VO101MMaister, if this design isn't going to go into production would you consider open sourcing your design? I'm currently investigating the possibility of building a sim-pit for a glider and am looking for a way to make my own control column and what can I say, this design looks FREAKING AWESOME!!!


All the best,
Slarti.
