In this video you will learn the method „Roving accelerometer“ to acquire the data for a modal analysis.
We’ll give you a brief overview about the following issues of this analysis method:

- the principle of the roving accelerometer method
- advantages of this testing method
- what sensors are required (accelerometer and impulse hammer)
- the necessary quality check of each strike (strike was good or bad)
- a typical analysis result and its interpretation
