Abstract in different language: The mechatronic modal hammer was designed and manufactured. Basic structure is relatively simple. However, suitable choice of mechanical parameters and smart control (feedback and feedforward) enables the device to achieve high parameter stability of impact excitation. The repeatability of the excitation force pulse is thus very high and long time measurement of experimental modal analyses is reliable and accurate. Furthermore, the mechatronic modal hammer is significantly cheaper then shaker. Mechatronic hammer installation is also very easy. This increases measurement quality, because several positions of excitation can be quickly tested to avoid modal nodes.
