Vibration research on a demolition hammer using a high-speed camera

Wojsznis M., Tabaszewski M., Dobry M. W.

Vibrations in Physical Systems

2012

Vol. 25

453--458

The paper presents methodology of measurements and results of vibration research on a demolition hammer weighing 15.5 kg. The measurements of vibrations for the chosen measuring points have been carried out using a Photron FastCam 1024 PCI high-speed camera on a stand prepared for testing hand-held tools. To ensure signal stability and to reduce the influence of an operator the research was carried out with the hammer mounted in a special fixture enabling holding a tool with symmetric layout of handles. The measurement results are to be used for verification of a model assumed for a human being – tool system.
