1.6. Vibration Response Parameters

Try these first

1. 1.

   Define amplitude in the context of vibrations.

   Hint

   Think about what happens when something vibrates.

2. 2.

   What does the phase angle indicate?

   Hint

   It’s like a clock between two events.

3. 3.

   What is the maximum displacement in vibration known as?

   • Amplitude
   • Phase Angle
   • Frequency Response

   Hint

   Remember the definition of displacement.

4. 4.

   True or False: The phase angle measures how quickly a system responds to excitation.

   • True
   • False

   Hint

   Think about what phase angle represents.

5. 5.

   Given a system with a natural frequency of 1 Hz, calculate the amplitude response when subjected to a 1.5 Hz excitation frequency. Assume it reaches resonance.

   Hint

   What happens to a system at its natural frequency?

6. 6.

   Design a simple model to calculate logarithmic decrement for a damping system with two successive amplitudes of 2m and 1.5m.

   Hint

   Use the formula δ = ln(A1/A2) where A1 and A2 are your successive amplitudes.
