Modal Space - In Our Own Little World

Is there any real advantage to MIMO testing?

Why not just use SISO and then move the shaker? Let's talk about the differences.

Multiple input multiple output (MIMO) testing has many advantages when compared to data collected from single input single output (SISO) testing. The energy from multiple shakers allows the structure to be more uniformly excited throughout the entire structure and thus allows for the development of better frequency response functions (FRF).

Modal Space - In Our Own Little World

How many points are enough when running a modal test? Let's discuss this.

I expected that eventually you would get around to asking me that question. Its another one that I get asked all the time. Basically the simplest answer is that you need to measure a sufficient number of points so that you can uniquely describe the mode shape. This answer may not be completely obvious. We need to talk about this a little more. Let's start with a simple structure that we have discussed before. The simple plate structure.

Pizza Reliability

Everything goes well with pizza, or so it seems, and the list of things that go well with pizza now include vibration test equipment, thanks to companies like Zume Pizza.  Zume Pizza in Mountain View, California, has innovated pizza delivery; they bake each pie in their mobile kitchens and are able to move those kitchens to the demanded location (i.e. sporting events, concerts, schools). The pizza is delivered to your doorstep moments after it comes out of the oven.
