Two Seater, 180 View, 3 DOF Flight Sim Platform

Hello All,

I opening this thread to record my build progress.

I'm a former embedded software developer, recently turned into a R&D supervisor that been dreaming of building a two seater so that my dad and myself could keep flying together once he loses in pilot license.

Watching Roland Schieller's 2 DOF platform made me realized it was possible with reasonable parts.

Like Roland van Roy I have a limited ceiling height constrain so I had a pretty good idea on how to attack the problem after looking at his DIY Motion PlatformIII http://www.simprojects.nl/diy_motion_platform_iii.htm

I still had one major problem. Maybe it's was in my mind but , I leave in Quebec/Canada I found it hard to find mechanical parts and precision metal working suppliers.

That all changed with my new job. I finally got the chance to meet very nice mechanical people that are building machines for a leaving and now I know about suppliers like:

• http://www.cbrlaser.com
• http://www.mcmaster.com
• http://www.misumiusa.com
• http://www.igus.ca/?c=ca&L=en
• etc.

I also managed to find an US company http://www.automationdirect.com that sell AC/DC motors, VFD drives and gear boxes at a very reasonable price.

My platform's characteristic would ideally look like this:

• 1.8m width x 1.5m length
• 2.13 m : Max Height including motion & heave
• 180 View : With 5 27" LED monitors
• 275 Kg : Max Platform Weight
• 20 deg : Max pitch and roll angular movement
• 35 deg/s : Max angular speed
• 0.080 : Max heave movement
• 1G : Max heave acceleration
• 4 actuators
• Actuator driven by 1-2 hp, 220 v, 3 phases, AC motor with VFD drive
• 24A @ 220V : Max source power

I'm at the design stage and I working at obtaining the drive motor characteristics from the platform parameters instead of designing the platform from the motor specifications.

I have been working for the past months on a set of spreadsheets that allowed me to reproduce a CKAS like platform that could not fit into my basement.

My newest version aims at designing a DIY Motion Platform III like platform that is not making use of cables and without a central pin for preventing swinging motion.

My ultimate goal, other than having my own platform, is to provide all spreadsheets, plans, technical knowledge I gained while building it to the community.

I'll surely have questions has I have not been doing maths and classic physics for the last 25 years but I'm sure it will be a fun ride building it.

I'll leave you with some images of what is to come and will be posting progress as I make them.

Platform MK-1.1

Actuator MK-2.1

Wouah!
what a nice project

I wish you good luck and success

Super Projekt! Klingt nach Seilwinden...great work, it seems you have built in some winches...

Thank you Pit,

Those are early conceptual sketches done with Sketchup.

I'll be finalizing them once my calculations are completed.

I'm trying to design them so I won't require soldering to assemble them.

I'll then have to learn Autodesk Inventor and redraw then to have a metal shop lazer cut the parts.

Possibly you learn more and quicker, when you learn welding instead of Inventor

Hello Value1,

It's not like I don't know how to weld is more like I not setup to use a TIG or a MIG at home anymore.

I had a lot out fun soldering my dad's airplane.

I should I thought about it twice before buying my second house with a carport instead of a garage.

Are you referring at welding as actually welding or some kind of software ?

Yes, I mean welding real stuff. I have the luck to have a well equipped public workshop nearby so that I don't need the space for storing the equipment when I don't use it. And the small space requirements of Inventor is a benefit on the other side

I must admit a recently went to a shop that sells MIGs that can be run on 120-220v.

History will tell if I buy one.

Been able to disassemble them may come handy to move them around.

I did not calculate their weight yet but I presume they should be kind of heavy even with holes in them.

I think they'll be made of 6 mm steel and about a 1 m height by 20 cm wide.
