Good luck nerd lol

Anyway one exam left wish me luck.

Woohoo,one more exam! You can do it!

Haha thought that would get some good answers, asked cause I couldn't sleep lastnight and remembered my buddy had this happen to him with a random, he wrenched away and accidentally elbowed her in the face. Needless to say her brother fought him and there were some awesome stories going around.

Penske has done regressive curve dampers. I've looked at it before and come up empty. There are also damping that increases with position, independent of velocity. Those are not too hard.

I'm taking a pneumatics class on Saturdays, and am starting to think about it again. Logic gates through valving. Must be able to do something with dampers...

I think the problem that we'll never get away from is packaging. Especially considering the stuff DougW is working on will male all of this obsolete.

That said my work with pneumatics didn't include logic gates. It was all vane & nozzles and needle valves to create PID controllers, square root converts, and flow sensors. I'm not sure what a pneumatic logic gate would even look like. Sounds like an interesting course.

Increasing damping with position would probably work well with progressive springs, but otherwise I can't think of a good reason for it.

Well Very simple logic gates, And, Or, Not. We are just doing physical programming with simple circuits. 5/3 valves, cylinders, pilots, physical actuation. It's neat, yet kind of irrelevant to my work because ours are all PLC controlled. So I'm thinking of car applications.

The position valving does come from progressive springs, but from motocross. Linear springs with linkages used for progressive rate increase for the big landings.

The packaging was something else I've thought about. Remote valving. The shock body is just a piston, and the valves are mounted to the chassis in blocks, with high flow, dry break quick disconnect fittings and tubing. Would be more for racing, so a shock could effectively be totally revalved in a very short pit stop. Could mount them in the cabin, maybe, for driver adjustments on the fly, too.

Things I think of when I'm bored...

Ah, that make since

That would be fucking cool! And it might just work.

Hydraulics are pretty much the same, right?

Any way we could tie in vacuum assistance like brakes, for certain applications? If high velocity is detected (pressure based?) we could use vacuum to balance it, creating less proportional damping (which is just pressure differential and flow control?) in that case, possibly regressing the normal curve?

Hmmm... 5 question marks in one post. Out of my comfort zone knowledge-wise. Heh...

LOL I like to wait for my crabs to clear up too before going to doctor!!!!!

[sklimo]

Sounds like you have the flu or worse. Get yo ass to a doctor quick.

And sorry you don't feel well

I've been sick for a month maybe longer and finally made a doctors appointment for monday. It'll be interesting what he'll have to say.

It's ebola. You have ten seconds to live. Sorry.

edit: I read the post after the one I quoted.. Trouble breathing sucks. I had pleurisy once and it scared the crap out of me. Every single breath was painful. So I went to the doctor, and then they started running tests to make sure my heart was okay. Thankfully a huge dose of ibuprofen several times a day for several days was the way to fix it, but oh yeah, definitely sucked. Hope you feel better soon.

Just get yourself an octopus. I hear they like to eat crabs. Careful with those suction cups though.
