In experimental modal analysis as well as in sound testing, a fully automated impact measurement is usually very important. Fully automatic in this context means an excitation point search and an adjustment of the excitation force are controlled directly in the hammer. No manual configuration steps are necessary for the user. The excitation force depends on several boundary conditions like the used impact tip, the acceleration and the mass of the hammer but also on the material properties of the excited structure. Therefore, the impact energy of the modal hammer is currently iteratively changed by the user until the target force is reached.

    Existing semi-automatic impulse hammers do not support fully automatic, reproducible and highly precise single hit excitation with freely adjustable force amplitude. Also other useful functionalities are currently missing in semi-automatic impulse hammers. The internal calculation of pulse describes parameters such as the pulse height, pulse width and frequency range of the excitation or if the single hit is reached for autonomous quality assurance. Single hits are possible with position changes of the structure or the hammer in impact mode. In addition to the use of a tripod, the hammer can also be held by a person and the hammer can be used manually guided for impact operation.

    Based on these requirements, a new smart impulse hammer was developed. This new and unique automatic impulse hammer is presented as part of this work.
