Beschreibung

In the field of experimental vibration analysis, various methods have been established for investigating structures for nonlinear vibration behavior. One possibility is excitation with the aid of a vibration exciter (shaker, see picture on the right, for example B&K Type 4809, www.bksv.com). The structural response is measured in various ways using accelerometers or scanning laser Doppler vibrometers. So-called step-sine tests are often performed. Here, a controller controls the desired force amplitude of a sinusoidal excitation with a certain frequency, measures the structural response and moves to the next frequency. This is additionally performed for different force amplitudes. The resulting effort for such measurements is enormous
