By solid state - I meant really solid state - was initially looking at various materials that expand/contract under electric or magnetic fields. PZT or GMR materials, for example. See http://www.adaptamat.com/technology/
Ill read up on VFD controllers.
The actuator has to be electric - its going to be operating in a retail environment, so as close to solid-state as possible. I had hoped there might be an actual solid state system out there somewhere, a solenoid perhaps, or magnetic clamps, but all of that seems pretty expensive.
I see your...
Im working on a similar problem, though on a much smaller and simpler scale.
The design I currently have involves two compact hydraulic cylinders, spaced about 100mm apart, lifting a platform as distance of about 10mm.
Planning on using something like this wrench powered screw-pump...
I'm looking for an electrically powered actuator for use with something like a stamping operation.
It should have the following characteristics:
Needs to travel 10mm in 1s, precision of movement not so important, but should have a soft "landing" at the end of its travel.
Needs to apply a...
You're right, of course. Eating/drinking the contents is the carnival way to demonstrate safety, aimed at people who's concentrations run out after the first 140 characters of a document.
Thanks for your thoughts - really appreciate it.
I say that this product needs to be non-toxic, non-hazardous, non-corrosive and non-regulated, because I want be able to walk into a boardroom and demonstrate its safety by eating/drinking some of the contents of the product. The people I need to...
Hi - I am working on a product that requires a concentrated acid, but this product must also be non-toxic, non-corrosive, non-hazardous, and non-regulated.
I looked into carborane superacid, but this stuff is too exotic and too expensive.
Instead, I have been looking into ion-exchange resins...
I have some samples of ultra-high index glass microspheres.
The microspheres are in various sizes from 50um to 300um, and the refractive index is reportedly 2.4, but I want to confirm this.
The normal way for measuring the refractive index of glass microspheres is to immerse them in an oil of...
RPStress, what did you use to compute the Glass/Ti and Glass/Al stiffnesses? I have been using various online beam bending calculators, but havent found one that works for laminates.
Ugh - you're right my numbers are confusing.
There are two situations I am trying to model:
First is daily use - dropping the thing or throwing it around. Ideally, as a demonstration of its toughness, I'd like to make a video of someone banging nails into wood with the glass face of the...
Hi RP,
Thanks for your comments.
Right now, the substrate is going to be metal - either 2mm titanium or 3mm aluminum.
The constraints on the substrate are that it should be thin and have a high yield and microyield strength. Basically, a human being should only be able to permanently deform...
Window films generally go on the front face of the glass. In my case the goal of the glass is to provide a scratch-proof surface, and any plastic film on the front face will negate that.
The glass I am using is a chemically hardened borosilicate or aluminosilicate glass, and the backing...
I am building a device comprised of a 0.5mm-1mm thin glass layer bonded to a rigid structural backing layer, and this device is required to be impact resistant.
The impact resistance test for the glass is the ball-drop test, and I am wondering if there is a way of estimating what adhesive...
