Dear all, For a project I'm going to design a servo system that will output an amplified hydraulic pressure, whereas the input is a force or pressure as well (not per se hydraulic). Output and input must directly connected due to the force feedback. I don't have a lot of experience with...

I'm trying to damp an oscillating metal plate with a neodymium magnet. Things I know - Remanence of the magnet - The magnetic flux density at distance z (from the distributors site) - Dimensions of the magnet - Plate material (Aluminium) - Distance to the plate. What I'm trying to find out is...

Wow that's nice, really easy to adjust an non-contact, awesome. Thanks!

Hello, I have a mechanical motion platform. It's only about 8 grams and about 5x5x5 cm. I'm a bit worried about the natural frequency and I want to mechanically damp it to slightly under-damped. I'm using phosphor-bronze for my spring elements, I'm not sure how much damping is intrinsic to...

Linear displacement by flexure, spring or ? I'm doing a little project of mine and I have encountered a problem.. The project is basically a motion platform that moves in three directions at very low forces (few mN). I got the first two direction done (X,Y), but the third is giving me...

Hello, I'm new here and that's because I've run into a problem I can't reliable find anywhere else. I guess I need some personal experience or input from someone. I'm designing a force sensor for a project of mine, it will be measuring force in three orthogonal directions. Now, I'm confident...
