Impact Hammers are used for Impact-force measurements on small to medium structures such as engine blocks, car frames and automotive components.while accelerometer is used to measure the response of the structure.Impact hammer is characterised by Ergonomic handle for optimal control of impact, thus reducing the risk of double hits and Negligible changes to dynamic properties of test structure.The hammers also have built-in acceleration compensation that removes unwanted noise from the resonance of the hammer from the output signal. This results in a clean, smooth output signal representing the excitation in both amplitude and phase.The impact hammer is supplied with three replaceable impact tips of aluminium, plastic and rubber.The choice of impact tip determines the impulse shape (amplitude and duration) and the bandwidth of the excitation.
Impact-force measurements on small to medium structures
As part of a dynamic structural testing system for modal analysis and the prediction of structural response
Measurement of frequency response functions using impact excitation techniques
Four types with sensitivity from 1 to 22 mV/N
Three replaceable tips
Negligible changes to dynamic properties of test structure
