The analysis of natural
frequencies and mode shapes of articles under test are of interest in many
different fields. Engineers use these results for the design and improvement of
everything from cars and rockets, to silicon wafer production systems.
In the example of automobile development, a
modal characterization of the vehicle can be used in multiple ways. One such way
is for the validation and updating of numerical simulation models. By using the
Modal Assurance Criteria (MAC), engineers can judge the correlation between the
model and the prototype. A higher fidelity model can then be used to achieve
better results for studies such as ride comfort or durability.
Utilizing the signal generator output to drive
a modal shaker, along with input channels to measure the response, the
MICROQ can collect all necessary data for
calculating the modal characteristics of the article under test.
