Vibration-induced loads stress electronical equipment particularly in automotive applications. If these high cycle oscillations excite the natural frequencies of electrical devices or circuit boards, malfunctions by material fatigue are likely to occur and the functional performance of the electrical system is affected. The assessment of the load impact, which is typically initiated by random noise of frequencies up to 2000 Hz, demands the full description of the system's dynamic-mechanical behaviour. In this paper a multi-dimensional approach of analytical, numerical and experimental methods is presented to evaluate the vibrational resistance of a power electronic circuit board applied in an automotive drive inverter.
