Abstract
This paper Presents the performance test of an impact hammer drill in conjunction with the parameter consideration of coefficient of restitution, lubrication and friction, pressure leakage, vibration damper and production quality. Novel measurement setups are innovated in order to get the Parameter data. The measured data are compared with the computational results, and this comparison gives a confidence on the computational model, which can be used for a optimal design of impact hammer drills.
