Yes this is why I asked the question but based on the various responces above I have been steered away...

Thanks all, I'm not a NVH guy so I was just stabbing in the dark. I'll opt for the high speed camera approach.

>>>How are you, "noticing that the fit of the tank is loose when shaking?" How much "loose?" Just by watching it shake and seeing daylight between the top of the tank and the hard mounting points. I would say it's roughly 5 mm. It's apparent that the design needs to change, however, I would...

Background: I have a "rigid" metal frame attached to a vibration stand. Housed in the "rigid" frame is a plastic tank with hard contact points on the top and two steel bands holding the tank on the bottom. The two bands fasten to the sides of the "rigid" frame and when tightened compress the...

CESSNA1, Thanks for the reply. These are various auto suppliers requirements for validating chassis components.

Lost! I'm wrestling with an aging brain and an education that happened too long ago and involved too much beer and too little class. I have three vibration requirements and am trying to compare the two for their severity. 1) 13Hz, 3G, 1.5M cycles. 2) 30Hz, 3G, 0.5M cycles. 3) Hz g^2/Hz 5...

I would like to thank everyone who has given me their input thus far. I'm going to have you losing your willingness to help through my stubborn ignorance however: Instead of the cylinder/plate example what if I consider two concentric cylinders of infinite length with open ends with the outer...

I agree that for a complete solution all paths/sources of radiation, convection, and conduction need to be considered and it does scream for an FEA solution. However, what I am trying to do is generate a 'simple' equation based on radiation heat transfer which can be used as a rule of thumb...

I'm still trudging through the theory and trying to get up to speed. However, the attached picture defines (well at least I hope it does) the problem I am trying to solve. I guess I could simplify it by neglecting gravity and assuming the pipe is a black body. Anyway I'll be back with many...

Thanks. I found an online text through some links elsewhere on this site. The more I read I realize I'll have to consider everything as suggested as feedback here. I'm sure I'll have many more questions once I re-educate myself. I was looking for an easy way out but I guess that's not going to...

Heat transfer was not one of my strongest classes and I've been out of school long enough that my text books didn't make it through the 15 moves. Anyway, I seem to be lost on the fundamentals as I search the web for information but here is what I am trying to do: I have a cylinder (automotive...
