Shock exciters

The family of SPEKTRA shock exciters is wide-ranging and based on different kinds of working principles of the shock excitation.

The principle of the hopkinson bar is basis for the shock exciters SE-220 HOP-MS and SE-221 HOP-HS. The high-shock model SE-221 HOP-HS provides the necessary force impact with a, by the use of pressurized air, accelerated projectile which impacts the end of the bar.

The SE-220 HOP-MS shock exciter for medium shock amplitudes goes a completely new way. It provides the force impact using a piezo-aktuator (Patent pending). This allows new possobilities to control the mechanical shock signal and with its new applications in the field of the calibration and in particular in the field of measurement and test systems (e.g. to test the shock sensibility of MEMS sensors).

The pneumatically driven shock exciter SE-201 PN-LMS uses the hammer-anvil principle to generate the shocks. A projectile that is accelerated by pressurized air is used as hammer.

The shock pendulum SE-210 SP-LS with integrated reference sensor completes the portfolio of the SPEKTRA shock exciters.

Hopkinson bar shock exciter
   

SE-220 HOP-MS

Medium-shock exciter for the amplitude range from 20 gn up to 4,000 gn. This exciter provides the force impact using a piezo-aktuator (Patent pending).

This allows new possobilities to control the mechanical shock signal and with its new applications in the field of the calibration and in particular in the field of measurement and test systems (e.g. to test the shock sensibility of MEMS sensors).
