To find natural frequencies in a structure, we need to excite the object and measure vibration levels simultaneously at the point of impact (head of the hammer) and elsewhere on the object. Then, with the Frequency Response Function available in m+p software we can calculate the natural frequency.
In this process, the value of the Shape Mode can be determined in the modal analysis mode and the frequency responce of the object will be visible in the software.
For this the VibPilot is easy to use and portable hardware, available in 4, 8, and 16 channel versions.
The m+p analyzer software already included the FRF function.
