Description

Mechanical impacting is involved in many technical process such as demolition of concrete by chiseling, structure borne sound analysis, impact-echo analysis of extended structures, characterization of material properties at high strain rates, and indentation hardness tests.

To generate an impact a hard-mass body is accelerated during a starting phase (e.g. a hammer head) and collides with a hard counterpart (e.g. chisel) within μs.

The starting and contact phases of an impact scenario are difficult to be exactly reproduced. Common setups of precision impact measurement do not allow high repetition rates. Another challenge is the precise timing of the impact. Meanwhile composite materials require more and more accurate testing methods. hpower shock generators follow a different approach. Our piezo technology uses an adaptive impact generation principle, where impact parameters and timing are controlled by electrical driving conditions. Thus – hpower shock piezo actuators have advantages over traditional solutions.
