Hypothetical

Question 1

There are different types of motion sensors. List three different types and discuss their advantages and disadvantages in the context of measuring accelerance functions for an experimental modal analysis.

Answer 1

….

Question 2

What excitation method would you choose for studying a certain frequency range? Basis for choosing a hard of soft excitation source? For this project would you use a hard tip or a soft tip?

Answer 2

…

Question 3

How do you decide if you want to move an accelerometer many times while only exciting in one point or exciting in many points with one accelerometer in one position? (aka exam question)

Answer 3

If you hit the same point again and again you’re kind of creating the same movement again and again. If you choose to place out many accelerometers you may end up on many node lines(?)
(accelerometer on one point big chance to miss modes. Move the accelerometer a lot you will receive more information. Excite in many points for a better chance to find more modes)
