ATJ Graphite Strain Data Verification of fundamental modes of target response
Record of strains in the middle of the graphite rod (left) shows a bending frequency between 380-390 Hz
The prediction of the detailed model that implements the supporting/holding fixtures of the target as close to the real setting as possible, predicts a bending frequency of 395 Hz
Also from the record, the axial “ringing” of the target has a period of 260 to 265 microseconds. The fundamental axial period T=2L/c (where L is target rod length and c is speed of sound) is approximately 261 microseconds
The radial “ringing” on the other hand, which from theory is calculated at 150 KHz (or 6.625 microsecs period), is visible only in the strain record filtered by the 500 KHz acquisition
