Hi all

[kenneth]

Hi My name is Kenneth and I am mad about sims I have built several over the years but this build its the biggest I have done so far. I have built a large shed 5m x 8 m a motion platform for this one and CNC with a 1200mm base for other bits.

My first motion sim was a for one person but this was dismantled to build the bigger one.

Here is my build to date  http://www.flickr.com/photos/56042374@N06/

Hi Ken,

Welcome to the CB and thank you for posting a link to your photos, it really helps put your build into perspective. I noticed you were doing a classic 737, and then switched to the NG. So, with your motion platform, how much weight is are you dealing with, before and after the changes?

It seems that you're using wood for the shell, moldings and base; thus, I am wondering what motors you have to use in order to move it all? Also, what degrees +- and how many DOF are you using? How much power is required for each motor in Amps and are you using 220v or 440v (some motion platforms need that much I've heard).

Also, I am just curious, are you planning to stick with wood or changing to real shell or something like an FDS shell in the future? I ask because mine is a real shell and weighs about 900lbs, so trying to compare it to what your weights would be.

Again, welcome to Cockpit Builders,

John

Hi the sim has a metal base frame that will have the motors connected to they are 12v but 10 rpm this way i have around 450kg per axis 3of them. if you have a platform for a jet you do not need to move it very fast each axis will do half a revolution and go from 100mm negative to 100mm positive in 3 seconds the axis points are about 1200mm apart so the front axis can go - 100 and the back can go +100 giving a pitch over 20 degrees that's is more than enough if you have no peripheral vision then you will not know how far you have gone looking out the window you may be 30 degrees and believe it. when in the air you do not feel the bank angle you only feel the start of the bank and then some heave upwards or down wards.

dealing with weight i have built a cantilever support for the middle of the platform the one in the video is fixed but I wanted some heave so the middle point has a 1.5 tonne spring in it

hope this helps

Hi Kenneth,

Thank you for posting and yes, your info helps a great deal. With 450kg or about 1000lb per axis that should be enough for mine, if I pursued it. Mainly, because with your cantilever support, no one axis has to lift the total amount of 1000lb collectively, and with that in mind, your total weight of the sim could/would be higher. Unless, I got this wrong in my thinking?

Please continue to post more updates as you progress.

[kenneth]

you are correct

if you have 2 pilots say estimated weight max of 110KG =220kg

mip overhead chairs bits and bobs say 200kg
then you have the base and screens and surrounding fuselage or enclosure say 200kg

costs per axis
motor £300  438kg per cm          http://uk.rs-online.com serch for part number 224-8204
driver card £100
position detection £60
mountings £70

if you went servo motor then the cost would be
motor £3000 with driver per axis
then io cards £200

Hi Kenneth


I used to live in Cambs. Now in Essex but still visit on a regular basis.


Be nice to have a chat with a fellow 737 builder now and again.


If you're open for visitors, or would like a helping hand anytime. Drop me a line.


Nice Sim.

Hello Kenneth,

Great photos of your Sim Project.   You are a brave soul to tackle a full-motion Sim Platform.  How is it performing to date?

I especially like the very clean and rather elegant mechanical design for your sync'd Rudder Pedals.  Nice job on this system!  I think I will follow your lead on this system for my own Rudder project.  Thanks for sharing.

Mike
