6DOF with VR Hardware Cessna Cockpit

[gaco]

Hello,

I introduced in the Newbee corner.
The Idea is to build a 3DOF Platform with Cessna 172 Hardware Cockpit for MSFS 2020.

First I downloaded the Instrument Panel

Then I draw the dimensions

Then I was beginning looking for Actuator. But all the recommended motors with wormgear or planetary gear is too expensive and I have a bad feeling for this, so I start to think of taking

HPV6 Linear Module SFU1204 Ball Screw Linear Actuator with HGR15 Linear Guides with NEMA23 2.8A 56mm 57 Stepper Motor - 200mm

idea is to place on bottom.

I am not realy happy with that , next I will try to add a lever to get max. out of the linear actuators. Advancage of this is the normal G Forces go into the linear guidance, NOT in the spindle (mostly)

Let´s see,,,

I am still finding out what I need to connect everything to work. All I read is "Audorino" and "Sim Tool". I have no Idea if I can use AC Servomotors with integrated board and if yes, what should the motor give for outputs to something I do not know to connect.

On the mechanical side I am ok, and am away from the first idea.

I will use ONLY a ball screw 1605 with a servomotor directly attached with Kardan on both sides (one side the nut, other the motor or fix bearing block). for the 16mm spindle no linear guidance needed.
The ball nut will be mounted via Kardan direktly to the upper platform.
The motor on the other side will go directly on the ground plate via Kardan.

All how to documentation here is from 2013 or 2014. I can imagine something changed from there to easyer fit into Win 10 or concerning motor parts or drivers. I will continue reading the whole google... takes time

let´s see...

Things are getting shape.

Cheap looks different, but it should work and last long.

Now it´s time to detail my CAD Model of all getting together.

Did I forget any important component in my scheme?

First mechanical calculation concerning the forces. The waves is a result of still free rotating Motors, I have to fix them later on.
First calculated Z travel 100mm in 1 second.

From step to step I approach the typical design with single levers attached to a gear :/
In the picture I made a design with 90° levers actuated by linear stages under connected with rods to the levers (not shown)

But The price is the same when I take worm gears or planetary gears.
So perhaps I do it like all other and make a Platform with Levers.
