Setup Automatic modal hammer
Bad excitation
If not set up correctly, the load cell will also be loaded in the transverse direction. The load cells are designed for measurement in the axial direction. Transverse forces that occur are not measured.
In the case of a non-vertical impact, the test object is excited at an angle and the vertical impact force is unknown.
Good excitation
When operating an automatic modal hammer, the precise setup of the hammer is important in order to obtain good transmission functions.
To do this, the tip of the hammer must hit the measurement object at a right angle. In this case, the load cell is subjected to axial stress and guarantees that the force is transmitted correctly.
