Spatial model of a human being - demolition hammer system

The paper presents a model of a Human being – Demolition Hammer system (C-MW) taking into account the motion of the system in three directions x, y, z.. The following models were used to create the model: Meltzer model from 1980, the model from the ISO 10068 standard and authors’ own Human Being – Big Power Driven Hand Tool (C-DZNR) model developed in 2000. Dynamic parameters were taken from the ISO 10068 standard for each direction of motion. Identification of tool parameters still needs accurate verification.
