hey guys, i need some help in finding information about dampers which are available today.
i am only in my 3rd year now, but have to submit a proposal for my final year masters project in about a month. as opposed to the normal aerospace research projects which are a bit boring unless you get the F1 one which all the hard core geeks go for, i want to do something bike related which i will have an actual interest in.
well, my proposed project is to have an electronically controlled damper of sorts. using electro-hydraulic servo valves to provide the damping and a position sensor on the piston shaft, then a standard PID controller to regulate the valves. the lay out i am thinking about is similar to a double barrel, so needing two EHSVs. making the damper having only favourable pressure gradients.
on paper it looks inviting as it will have a few advantages, it can be tuned with the P & D terms to make it position and speed sensitive. the only other damper which does that which i am aware of is the curnut control valve thing, but requires cooling for heavier applications. there is more freedom to play around with damping curves, adding lead or lag terms in the controller ect. and also having the advantage of having everything external, not needing to open the damper up for a different tune (of course as long as it lies with in the limitations of the EHSVs)
those advantages there are just pulled out of my ass really, and the reality of it could be very very different.
ideally you can refine it enough and make is small enough to fit it on a bike, but that's for later. right now i have to convince my lecturers that this is a project worth pursuing.
anyway, the main thing is that my lecturer needs to know how novel this idea is and what current research is done in this area which is or might be close to what i am proposing. i my self dont know a great deal of what is going on outside the world of bikes really, i know cars have some pretty smart systems but know nothing about them.
any help will be greatly appreciated!
Thanks,
Adam.
