Steady State Forced Vibrations

Question 1

What is the Frequency Response Function?

Answer 1

Function that contains information about vibrating systems.

Question 2

Complex Dynamic Magnification Function

Answer 2

(Xk/F) = 1/(1-r²+j2ζr)

Question 3

Quality Factor

Answer 3

Displacement amplification at resonance.

Question 4

Quality Factor Equation

Answer 4

Q = 1/(2ζ*√(1-ζ²))

Question 5

What to do if forcing signal not harmonic

Answer 5

Use Fourier transforms to give you a usable approximation.
