Hi all,
does anyone know where to get hydraulic cylinders and pumps to make my own simulator hardware? I thought of those parts they use for moving those lowrider showcars but these things are hard to find via the internet (wrong target audience I guess :-)). Can anyone help me out here? Best regards, Christoph |

Been thinking the same thing, look into pneumatics though, much more cleaner when there's a leak than hydraulics. Keep us all posted, I'm wanting to build something next year like this. Steve |

Here's a site of someone trying to create a sim motion base: http://www.cadsoft.de/people/kls/fltsim/index.htm Note that commercial bases run about $15,000 - $25,000. (!) Not to mention that you'll need some math background and have to write some nice algorithms to fake the motion. It is not just a matter of tilting with the scenery... that'll just make you feel sick. In motion sims, you do it another way: for acceleration, tilt back. For going up, lift everything. For deceleration, tilt forward. For banking, very likely lift everything also (to give the G-force feeling).. you don't tilt the base, because that's not what it really feels like to bank an aircraft. And finally, you need "wash-out" code, to slowly return the base to center without the user noticing. It's pretty complicated stuff, apparently. Kev |

Hi Kev,

It is not just a matter of tilting with the scenery... that'll just make you feel sick. You won't believe what you can find online (nah... you probably know it already :-)) After my first post I did some more research and now I know that I am not looking for flight simulation but for motion simulation (makes google-ing much easier). In motion sims, you do it another way: for acceleration, tilt back. For going up, lift everything. For deceleration, tilt forward. For banking, very likely lift everything also (to give the G-force feeling).. you don't tilt the base, because that's not what it really feels like to bank an aircraft. Back at the university (seems now ages ago) I studied Robotics and Automisation Techniques (though I have never come across these things again afterwards in my professional career). At the moment I am thinking about a 2-DoF simulator with roll and tilt motion. If I recall my mechanics lessons right I should take care to design the frame and seat so that the turning axis (btw, what's the plural of axis?) goes through the center of mass of the pilot's body. Pneumatics seems to be a good hint (thanks Steve). Neatly designed I hope to get away with only two cylinders. The inverse kinematics will be the next problem to be solved, if the motion information from games and simulators comes in angular velocity or something like that (I really do not know much about the interface technology at the moment). The electro-mechanical coupling of the electronics and the valves will another point to take care of. Variable movement rates are desireable and I don't know yet if that is possible with the standard technology. Anyway, all your thoughts are highly welcome. Tchaw! Christoph |

Oh yeah, here's an old link I have, to more motion links: http://www.isdale.com/jerry/VR/VRNew...formLinks.html Kev |
