Energy Absorbers in the Investigations of Hand Impact Tools for Soil Compaction

The analysis of the application possibilities of substitute soil - neoprene (type of synthetic rubber) was conducted during the comparative investigations of hand impact tools for soil compaction. The impact tool was experimentally investigated for the different types of soils: sand, moulding sand and neoprene. It was stated that actual soils are useless for the verification investigations. Neoprene as the energy absorber is characterized by the satisfying sample repeatability and this feature ensures the stability of impact tool work. Therefore, neoprene can well be used as substitute soil. This fact was confirmed during the numerical analyses.
