    Hi,

    It's been a while since I was here but I'm now a lot closer to a motion platform decision i.e. whether to pursue this area or not and was hoping for some opinions.

    I now have a better understanding of how big things are going to be and basically that's the limiting factor for me - SIZE or more precisely HEIGHT.

    I basically can only add a total of around 1m to my sim. So something in the order of 50cm in height when the actuators are fully retracted and around 1m when fully extended.

    This is a rough estimate and I would say this is probably going to be an estimate of the maximum height.

    Does anyone have any opinions on this?

    You've not provided much detail on what you are intending to build? Is your plan to make a 6DOF Stewart platform?

    Woops, thought I mentioned that, yes that's correct. It's for a flight simulator. Just civil aviation flight sim. In terms of how much weight it needs top support, I would be guessing at this stage but I'm hoping that it's irrelevant given that I'm sure there's a huge variety of actuators out there. If you need a rough estimate, then - 2 ppl... 180kg + sim itself in the order of 250kg so we're talking 500kg +- 200kg. So the question is, can you make a 6dof stewart platform as small as I described?

    I'm not experienced enough to give a complete answer, but the simple answer is yes I believe it can be done. My understanding is that for flight sims it is preferable to have greater degrees of motion than what would typically be used for racing sims and that the speed can be slightly less.

    Here's a couple of ideas for you to examine....


    This one is 3DOF but nice an compact....
