Thanks for the help. Unfortunately this is a rare situation at our company and no one really has any experience estimating damping factors.
I find it hard to believe that everyone builds prototypes to test what their damping is, or make guesses based on prior projects. It seems like there...
The 'fixed' end condition is based upon the flexible steel plate being welded to a massive chunck of steel. But what I called the 'rigid massless bar' is bolted to the steel plate.
1% to 2% critical damping means there will be a lot of oscillations which is not what I am looking for. What would...
If you assume gravity has no effect, and the inlet velocity is very small then Bernoulli's equations says:
Vexit=(2*(Pinlet-Pexit)/ρ)1/2
provided V2 is not more than 0.3M.
I'm not formiliar with critical pressure ratio.
However bernoulli's equation is valid for incompressible fluids only. Air is considered incompressible as long as the velocity does not exceed 0.3 Mach.
I am trying to estimate the damping ratio of steel in bending. I have a situation where I need to know the dynamic response of an inverted pendulum. A picture is worth a thousand words, so here you go:
The vibration will be free; it is caused be the initial position of the system. I can...
The key point to know when computing the laplace of the dirac delta function is that the
∫[f(t)*δ(t-ε)]dt from {0 to t} = f(ε) because δ(t-ε) = 0 everywhere except ε and ∫(δ) from {0 to ∞} =1.
If your pipe is small in diameter, the system resistance will be high. This will decrease flow and increase the pressure gain of the pump. However, you are only getting 1.5% of rated flow of the pump. I would not be suprised to hear that you burn up the pump or motor. Not to mention the pump...
Look up Bernoulli's Law.
Depending on your situation, can could assume inviscid fluid to simplify things.
You also have to be careful that the divergence of the section isn't too extreme. If it is the assumption that the velocity is uniform throughout a particular cross section will not be valid.
You should also check for buckling of the leg(s). If the slenderness ratio is high enough the legs will buckle well below the listed yield strength of the material.
Are there any program that be be used to read a .CAM file and pull measurements from the program.
Where I work we cut some elliptical holes that must have their size verified before cut. It would be benefical to have a reader program that let's you view the plot (not just the code) and take...
I am not really concerned with residual stresses from welding at this point. I would weld the beam to the plate, then put the strain gauge on the back side of the plate directly behind the bottom of the beam. Then load the beam. And take the strain gauge measurement.
