Working principle of PIA Shock Generators

When the piezo is charged quickly (short pulse), then the axial compression stress in the piezo ceramic instantaneously jumps to a large value. The blocking pressure is established, resulting in high accelerations with high strain rates. As a result the piezo-rod expands in an accelerated manner. The piezo stack can build up a propagating pressure front in a coupled body. Therefore the piezo is an “active rod” which generates mechanical shocks when driven by electrical power pulses.
