Experience

Dynamic mechanics serves measurement and stimulation for calibration and test.

Especially in the field of vibration excitation unique experience was gained in the past decade.

The aim of this complex was to develop electrodynamic and piezoelectric vibration exciters in the high frequency range up to 200 kHz. For the design and layout of the dynamic electromechanic properties procedures and methods based on mechanic and electromagnetic FEM are developed. These methods allow good prediction of the product properties already in early desing stages. Thus time- and money intense iterations for the final design can be reduced.

Background of these projects was the design of shock exciters with accelerations up to 500.000 g. Als physikal working principle the „Hammer-Anvil“ (force impulse due to the impact of two bodies) and the „Hopkinson-Bar“ principle (shock excitation due to wave propagation in long bars) were used. Besides my PhD thesis I developed design methods based on lumped mass simulation to predict the product properties.
