Full motion Home Flight Simulator

Hallo Gemeinde,

ich wollte mich hier mal mit meinem Projekt vorstellen.
Aufgabenstellung war, eine Motion-Plattform zu bauen, welche in Räumen bis 2,40m Raumhöhe zu betreiben und trotzdem 20° Neigungen in unter 1,5sek. schafft.
Außerdem sollte sie große Lasten über 300Kg stemmen können, da mein Homecockpit aus einer Stahlrohrkonstruktion geschweißt ist und für 2 Personen vorgesehen ist.
Das Ergebniss:

Viele Grüße aus Berlin,
Roland

That's great There's a lot I like about your simulator, e.g. all those screens!
The solution with the lifting jacks is very clever, indeed.
In your video you share a lot of technical details verbally. Would you be able to share some details also here in the forum?

Very impressive!

Hi,
The idea really comes from a jack. When I went one day by my garage, I saw this jack. There I found out the idea.

With pleasure I transmit technical details.

There is one more video with youtube. There one sees the drive in detail.

Top idea, think it was bsft who showed me some earlier pics of the build , well blow me over that is pretty damn cool.
More detail please.
i.e. any design info on remake of the jack ?
What's the size (voltage, amps) you are using ?

Thanks well done, love it.

Hi,
Thanks for your complements. So far I have no drawings ready showing exactly the design. If there is enough feed back may be I will produce the jacks on request.

The platform is driven with 24 V, and max 60A with a sabertooth controller. Maximum currents of about 100 A are coming up when the dirvers are turning into the opposite direction when moving downwards.

Best regards
Roland

Fantastic simulator! I love how you it can seat two people - very nice. :clap:

I am in awe, well done!

I too would like more information on your lift mechanism. How did you fabricate the lifts?

Thanks Ronald, thought you they were 24v units but had to ask, Im in the design stages of a 301 replica and think 24v is going to my option for lifting the main frame.
When you get time , I feel the community in whole would love to see a design of the jack , even a rough theory of what you have done, innovative indeed.
Right out of the square well done.

How are you driving the sabertooths , Ard or K8055, been working on supporting the new driver from dimension engineering, Kangaroo. As the K8055 is not support in the software and the Kangaroo looks way better apart from 1/3 of the cost and yes it can be setup with USB.

Great simulator, well done.

Any idea how heavy your entire rig is? Looks very solid!

Hi,
Thanks to all of you for your interest. I will try to answer your question:

The net weight of the platform is something around 500 kg.
Unfortunately I am not a PC programmer thats the reason why I - unfortunately - cannot answer everything in detail.
The sabertooth controler (2x 60 A) is drivern by the software of Ian Hopper.
The wiring is exactly as per his drawing ( http://bffsimulation.com/sabertooth.php ). He did a fabulous job to get this thing running.

Concerning more details I have to refer to my youtube videos showing the mechanical parts and drivers more detailed. Hope, that will help you.







Best wishes
Roland.

Great job dude!
:hi:

In the drawing one can well recognise, how high and deeply the jack goes. In the comparison a hydraulic cylinder (or linear engine).

yes, this is a compact actuator !
but the drawback is that speed is not linear.

Turning the axle in low position, moves up quickly. But as time goes, the speed reduces...
So the electronic has to compensate this.


The advantage is a nice and smooth movement ! It is well done !
Did you machine all the pieces or is it an electric jack you bought and modded ?

All mechanical parts are from my production.
First, I've experimented, such as speed and power are:


Then I drew a design:


At the end, a prototype was built:


So Easy!

1 motor turn will shorten the horizontal screw by 1 cm (<>L in my sketch)
- in low position, the arm will raise very much to compensate this 1 cm minus length of the screw
- once raised, the arm will raise few to compensate :


Considering this, I calculated it like this :

Could you tell me if you used ball screw or simple screw with a nut ? I can't see

I use ball screw.
Simple crew brake too heavily dignity.
