Hi all ..... soooo i have been working on building my motion platform for the better part of 2014 and planning since 2013. Im close to completing and i figured it was time to share my progress and get some opinions, thoughts etc etc. A little about the motion base ... it is crank arm based with an 8 foot base and should have a seated height of about 5 feet. It should be able to handle a payload of about 2000 pounds and the intention is to mount a full scale 737 NG or 787 dreamliner flight deck with full wrap around display system. Well thats the plan hahahahaha ... let me finish it first. Here are some pictures. In this picture i had the main frame cut and welded up .... The end caps are removable and held together using 6 bolts ... ************************ Here the legs are attached *************************** Motor and gear mock up .... ************************* Here is a close up of the motor seats. They are slightly raised so that i would get the bolts through the seat plate ***************************** Added some rear support legs to take some of the weight off the motor mounting face. ************ ****************************** Here all the motors are mounted. This was a mock up before any wiring had been ran ..... This thing turned into a freakin monster ..... Bigger than i envisioned it and i freaking love it !!!!!!

Soooo time to wire this puppy up ..... i had to get ALLOT of wiring. Especially since the control cart is separate and i want it to have a 15 to 20 foot clearance for any sim mounted. so i used over 200 feet of main cables. All motor wiring is ran through the frame to a junction box in the rear of the frame. ****************************** wires ran ..... took the better part of a whole day just to this part .... And before anyone asked, the signal wire for the position sensors is double shielded wire to maintain signal integrity *************************** Here is the little junction box i mentioned earlier ****************************

Now for the control cart .... it houses the VFD's, main computer for the motion and all wiring and braking resistors *********************** shot of the back panel. the wiring is not complete yet. that is what i am currently working on ***************************

Hi Jthiani,
I can't believe how fast you go forward with your building ! You work 24 hours a day , 7 days a week on it !! ;-)
Just for the space needed it's time to move it on a bigger room !! Congratulations for your job!

So today i got some welding done on the crank arms. I have not completed this fabrication as i still have to grind off the ears and weld the caps on. All in all, im glad with the progress thus far. **************************************************** Here are the ears im talking about. They still have to be ground off .... ********************************************** Heres a close up of some of the welds ...... Im relatively new to welding so they are abit messy hehe ******************************************** ************************************************* Here are the connecting rods. I had fabricated these a few months back

Hi jthiani,
Can you specify what motors, gearboxes and vfd's you use?
thanks!

Motors are 2kw each and gear box is geared to 15 rpm output. Vfd's are Huanyang 2kw inverters

Hello All... I'm in the process of building a 6dof Motin Platform to support my full-scale 737 Sim.

Hello jthiani,
Your project looks like it is coming along nicely. Very impressive workmanship! It is interesting that you too plan on placing a 737 Sim on top of your finished 6dof motion platform.
I see from your photos and video, that your Actuators are quite long with 15 RPM for the shaft output. This is going to yield a very fast response and potentially high acceleration. My concern with my own 6dof motion platform for my 737-800 Sim, was having too much platform movement and shock, which for my Sim module is a serious consideration. What does your 737 look like, and how is it constructed? What kind of sim displays will you be using for the flight deck, and outside scenery displays?
Keep up the good work.
Mike

Mike Hey mike ...... i too have been following your build and i must say it is very impressive. Where are you located?? Upon further consideration and testing, i have significantly modified my platform to incorporate a basket. This will lower the center of gravity and make the whole rig more stable. It also significantly reduces the amount of headroom required for a full 737 pod. I am planing on a full collimated display with a 14 foot mirror. This will come much later. Regarding to the output speed, since you can reduce this in the setup of the thanos board, i will play around with it to get smooth and realistic output.
