Modal hammers

Endevco hammers feature an Isotron impedance converter that provides an IEPE-type output, compatible with most FFT analyzers and data acquisition systems, and are designed to properly excite structures in modal and structural analysis applications.

Modal impact hammers are portable and cost-effective, providing controlled excitation to structures with no undesirable mass loading to the structure under test.

Scaled modal models also require precise force measurement, which can be achieved via a modal hammer fitted with a piezoelectric force transducer.

Applications with high crest factor and ability to shape the input force spectrum of minimal concern because impact hammers are an ideal source of excitation.

Hammers are designed to excite the test structure with a constant force over a frequency range of interest. In addition, certain selected models are acceleration compensated, to avoid spectrum glitches due to hammer structural resonances.
