First, a little intro -- I design metal brackets that bolt to trucks that hold various types of equipment, all furnished by a third party. We perform structural simulation (FEA) on all of our brackets, but we don't have much information on the equipment that our brackets hold. We currently...
Hello all,
I am running across a problem trying to analyze reactions in antenna brackets used to support whip antennas. The primary concern is our random vibration analysis. Many of the antennas have a spring base that keeps the antenna fairly "rigid" most of the time. However, when the...
Many of you seem to have a lot of experience in this field, so hopefully you guys can make this a little clearer for me. I have been asked to reduce the "vibration" of a camera mount (not vague at all, yeah) using random vibration FEA studies. I have been analyzing the displacement, since I'm...
I have been analysing a relatively simple assembly made up of two solid bodies and a sheet metal body -- it's a sheet metal bracket bolted to a truck that holds two copmonents (both are bolted to a vertical face). The error message that I'm getting comes when I try to copy my frequency study to...

Anyone heard of this? http://www.angellabsllc.com/index.html
I didn't have a whole lot of time to look over it because I had an 8am test, but it seems interesting. I don't think they have done any actual testing where they ignite a fuel/air mixture, but they have done what they call "air...
I know the effeciveness of ceramic coating is kind of a controversial issue, but I was wondering what you guys thought. I understand how polishing helps by minimizing surface area, but does it really "reflect" heat? What are the advantages of each in the combustion chamber of the head and the...
Hey all -- I've been a long time lurker, but just now am getting around to my first post. Great info on this site! Anyway, I know it's common practice to keep the step between the exhaust port and the header, but how important is it on a turbocharged vehicle? Should there be any steps to...
