Piezo actuators for material testing - PIA shockwave generators

Repeatable shocks with timing in the µs-range

Some applications like material testing work by using impact methods. These impacts / shocks can be realized by ballistic methods. Although the methods work with low repetition rates and they do not show a high repeatability. Furthermore the exact triggering of the impact event in the µs-range is not possible. These limitations are overcome by the piezo technology used in mechanical shockwave generator principles.

Piezo shockwave generators of the series PIA from piezosystem jena are specially adapted systems that are capable of generating high accelerations (up to 500.000 m/s²). Shock source and sample are in contact before the impact. An exact triggering of the impact event in the microsecond range is possible based upon this non-ballistic principle. This principle will produce extremely high repeatability rates of the impact parameters. Special designed piezo shockwave generation electronics can reach impact repetition rates up to 1 kHz. The impact parameters, such as energy, acceleration and pulse width are adjustable.
