Abstract

For a life time optimized construction the knowlegde of dynamical assemblies load is one of the basic requirements. This fact is especially relevant for smart electronic structures. To analyze the load vibration investigations and vibration tests are necessary. For such investigations ofelectronic structures contactless working lasertechniques are used. In the last few years experimental modal analyses based on laser vibrometers have been established. The results of such analyses show eigenfrequencies, vibration amplitudes and mode shapes. Based on this structural modifications concerning a vibrational optimization are inferable.
