Impact hammer is a fast, simple, and effective method to calculate structural modal parameters. It utilizes the force sensors integrated into it while striking on the surface/structures being tested. With current testing techniques and Fast Fourier Transform (FFT) utilizing a computer, the pulse signal collected by the sensors is processed very rapidly based on pulse test principle and modal theory to calculate the structural modal parameters. In the hammer method test, the input is the impact (hammer) force signal on the structure. By measuring the response (output) acceleration signal at various points of the structure, the transfer function of the structure can be obtained and thus the vibration characteristics of the modal shape and natural frequency of the structure can be calculated. 2.
