Science and Education Publishing American Journal of Mechanical Engineering 1 7 2013 11 26 Mobile Mini-mechanism for Moving in Pipe with Small Diameter 262 265 EN Alexander Gmiterko Erik Prada Technical University of Kosice, Department of Applied Mechanics and Mechatronics, Kosice, Slovakia AJME20131722 10.12691/ajme-1-7-22 2013 10 15 2013 10 22 2013 11 26 The paper deals with a mobile miniature mechanism which was moved inside glass pipe. The mobile miniature mechanism consists of driving and driven body, which is moved by magnetic force. In the theoretical analysis of miniature mechanism movement its mean velocity on the base of two elastic masses impact model is examined. In experimental part dependencies of attractive force and repulsive force on distance are examined.
