Paper Abstract

Knowledge of dynamical load behaviour is a basic requirement for life time optimised design of different products. This fact is especially relevant for smart electronic structures. Different non-contact working laser vibrometers (single-point and scanning) are used for vibration investigations and experimental modal analyses of such small structures. The results of this analyses show natural frequencies, vibration amplitudes and in case of scanning vibrometer also mode shapes. Based on this, structural modifications concerning a vibration optimisation can be derived. The measured results serve also as basis for numerical simulations and for FE-model validation.
