    Simulating G-forces?

    in Home Cockpits

    Posted

    We need more Stuff like yours Harry! :-) Btw. now i'll try to add a crank actuator to get a 10cm heave axis (single Seat plate - so to say a cheap version of your 3DOF Servos). My Tension System can't replicate very soft, light and fine heave movements. So i hope this new crank system do the job.

    Unfortunately the belt tensioner shown in the video did not last long (I need extreme forces because i fly inverted in the 360° motion sim).

    So I rebuilt it and now the belt tensioner works perfectly and generates 100kg traction. Below i added the sketch as PDF. What you need:

     

    1x 360° absolute encoder (Hall Sensor), analog, 0-5V

    https://www.megatron.de/produkte/hall-effekt-singleturn-drehgeber/halleffekt-absolutwertgeber-serie-mab25a.html

     

    1x Arduino Uno

     

    1x Sabertooth 2x25 H-bridge

    https://www.dimensionengineering.com/products/sabertooth2x32

     

    1x DC brush motor 24V ; 350W ; gear output about 300 rpm ; with chain wheel 11 teeth.

    If you'll get a (more expensive) gear DC Motor with 100rpm you will not need the chain (direct drive like in the sketch)

    1x chain wheel with 27 teeth, hole diameter 25mm

    1x matching chain approx. 50cm

     

     

    2x Bearingblock (ball bearing) d=25mm

    https://www.ebay.de/itm/4-Stueck-UCP205-Stehlagergehaeuse-Lagerbock-UCP-205-Stehlager-25-mm-Welle-/291589861281

     

    1x drive axle d=25mm; approx. 13cm long

     

    1x belt pulley with belt to control the encoder

     

    1x 3mm Steelrope or extremely tear-resistant textile tape (safer!):

    https://www.extremtextil.de/edelrid-x-tube-schlauchband-16mm-meterware.html?number=71800.APFLGRU

     

    1x USB cable

    10x various pin header cables

     

    2x lead gel battery with min. 8Ah/12V

     

    1x motor mounting

     

     

    - Install and configure the free X-Sim software according to these instructions (be careful, use the Sabertooth variants):

    https://x-sim.de/forum/viewtopic.php?f=39&t=723

     

    - Connect the PC to the Arduino via USB cable. Connect Arduino to the encoder and Sabertooth using the PinHeader cables.

    - Connect the DC motor to Sabertooth.

    - Connect the two 12V batteries in series (24V) and connect them to the Sabertooth (CAUTION! Plus to plus otherwise it smokes!)

     

    - Connect the DC motor to the Sabertooth (M1A and M1B)

     

     

    If everything works in x-sim then you have to use the Export.lua from DCS. I will send you on request.

     

    Then start DCS-Import.exe as admin (you always have to start x-sim before, otherwise it won't start).

    Then start X-Sim Extractor as admin and configure the DCS-Plugin (help on request)

    Press Play in the Extractor -> X-Sim Converter should start.

     

    In X-Sim Converter under Interface Settings activate XPID. CAUTION: Motor will now start to rotate.

     

    - Create an axis in the converter and install the G-Force effect (help on request)

    - Then press Start in the Converter

    - Start DCS. Commence mission.

    - In X-Sim the Input Values should now arrive in the Math Setup.

    The target line must change when you draw Gs for example.

    - Now the engine should turn!

     

    - Extend the battery with an emergency stop switch within your range!

     

    - Now connect the textile tape to the 25mm drive shaft (hole drilled and tape pulled through and glued.

     

    - Close the belts and test if the pull is not too strong and everything holds.

    Caution! The belt can cut off your crown jewels and fingers because it runs directly between your legs -> cable duct and protective cover

     

    And now sit in, fasten the belt (with cutter in hand just in Case),

    and have fun!

    Old post, but maybe some one has interest in this:

    https://www.youtube.com/watch?v=eVtvAbWfoqk

     

    The hole harness is pulled down on positive Gs (heave). In the video you don't see much movement (you can heare more), but the tension system generates up to 100kg now divided on shoulders, chest, back and bum.

    I was quite surprised how realistic the feeling of the Gs is.

    Pulling 9Gs (with F/A-18 in DCS) feels like 3.5Gs in a real Airplane! When i breath out I almost loose the Air at max. Gs!

    Sure, there is no Blooddrain or Blackout but however it is a perfect instrument to feel the energie state of your Aircraft. Every G is distinguishable.

    Hmm i tested the piston engine effects in P-51 and FW-190. In both planes the effects are quite the same. It´s like a bumb with a repeat time from 2hz to 10hz and some small amplitude changes...doas not feel realistic...should it not be 500 to 8000 bumbs per second?

    But maybe i do something wrong. I only have one buttkicker, no mate.

    Hello Andre and f4l0,

    i really want to thank you for this Tools! I think it's a great help for flying besides the increased immersion. Finally I can feel if gear/brake is really out or not, or if I'm too fast for the flaps. Buffets can be felt perfectly on the stick. At touchdown each tire hits me in the back one by one, the timing is 100% right..how did you do that???

    I use a IBEAM and and had to decrease some effects, but now it is just perfect!

    Thanks again, also for all the support!

    Hello Andre,

    i installed the SimShaker Sound Module. I have a onboard sound card (realtek) and a dedicated soundcard (creative xfi).

    Both cards are 5.1 and all channels are working. But both don't work with simshaker. First message:

    21:37:1.783 SimShaker Sound Module | Version 2.12

    21:37:2.134 Could not find stored output device. Trying to use default output device 2- Realtek® Audio

     

    after switching to xfi:

     

    Thank you for using SimShaker software!

    Visit me .....

    21:4:28.830 SimShaker Sound Module | Version 2.12

    21:4:29.20 NaudioPlaybackEngine: could not initialize playback device.Exception from HRESULT: 0x88890008

     

    message realtek:

    21:22:26.533 SimShaker Sound Module | Version 2.12

    21:22:26.773 NaudioPlaybackEngine: please check if required ASIO driver is presented

     

    I installed SimShaker as admin, give all network rights and disable the windows firewall. I run win10. Can you may help me with this?

     

    Update: Now SimShaker doas not start anymore. I added the error.log

    Update2: After reinstall and setting up everything as mono (both soundcards stero mode) it works at least with the realtek, but not with xfi and not in

    5.1 mode. I'm confused :-)))

    Export Values for Engine Informations

    in PC Hardware and Related Software

    Posted · Edited by vJaBoG32_Siddharta

    Thx but doa'nt work, at least at most aircrafts.

    I'll noted that simshaker uses the Instrumentpanel for this:

     

    get_argument_value

     

    e.g.

    local RPM = MainPanel:get_argument_value(50) * 100

     

    But the responsible value number differs for every aircraft.

    May someone know how i can figure out the right panel value number?

     

     

    EDIT: found it. Values can be found are under

    Your Drive:\DCS World\Mods\aircraft\*Aircraft*\Cockpit\Scripts\mainpanel_init.lua

    Export Values for Engine Informations

    in PC Hardware and Related Software

    Posted

    Hello all,

     

    i'd like to export the DCS Engine Values:

     

    LoGetEngineInfo() -- (args - 0 ,results = table)

    engineinfo =

    {

    RPM = {left, right},(%)

    Temperature = { left, right}, (Celcium degrees)

    HydraulicPressure = {left ,right},kg per square centimeter

    fuel -- fuel quantity kg

    }

     

    But none of these values seem to work.

    Or did a make something wrong? ...

     

    function LuaExportAfterNextFrame()

    local engine = LoGetEngineInfo();

     

    socket.try(c:send(string.format("RPM = %.4f, \n", engine.RPM))

     

    end

    end

     

    If no error...is the another way to get these values e.g. via exporting instrument values?

    If yes, how?

     

    THX for any help!!!

    To open the box of Pandora´s box here again: It´s not about Euler Angle. Neighter about using them to achieve G Forces. Nor it´s about position simulation. Even with the best 6DOF Hexa and best Filters you´ll not get realistic G-Forces - not even a reduced realistic simulation of Gs. Reason is that most 6DOF are based on OnSet Cueing Effect. But OnSet Cuing works only very limited, it can not simulate constant forces. And OnSet Cuing can not trick your brain good enough to simulate big inputs e.g. for aerobatics oder millitary envelope.

     

    So imho it´s all about simulating CONSTANT G-Forces and constant Roll-Rates! And it´s about the sense of balance (yeah good old position again).

     

    This things can maybe achieved with new Concepts like this:

     

     

     

     

    Every Force generating System has false inputs or missing inputs.

    Mixing the different Force-Systems together can overcome allmost all issues.

    E.G. just add a stupid belt tensioner (positive Gs) into a 6DOF Steward Plattform.

    It´s a game changer for sure!! Suddenly G load is perceptible. Even with just 80pounds tension-force, it´s like a new dimension. And that is just the beginning: Think about torso tension systems, tactile transducer and 360° Systems.

     

    So that´s my future dream of G Simulation :-)

    Motion Platform

    Ja, das mit dem verrückt sein stimmt schon...wobei durch VR zum Glück immer mehr Leute auf den Trichter kommen *g

    Fangen wir mal an: Wenn ich das richtig sehe kombinierst Du Gurtspannung und Druck/Entlastung durch die vier Panels, richtig?

    Wie kombinierst Du das? D.h. welche Kraft wirkt wann am Gurt und welche an den Panels?

    Und wie kombinierst Du die Bewegung von deiner Motionplattform dazu?

    Ah und ich seh Du ziehst hinten an den Gurten an. Entlastet ein Zug an den Gurten damit nicht das Becken bzw. die Beckengurte?

    Ist schwierig meine Fragen in Worte zu gießen und falls es Dich nervt, einfach ignorieren :-)
