Abstract


The work is part of the doctoral thesis, in which the action of vibrations on an operator serving a machine tool during the production process is studied. The paper carries out the theoretical study of the transmission of vibrations from the machine tool through the operator's feet, which is placed on a pedestal on which there is a rubber mattress. Consider vertical vibrations, through both legs, up to the abdomen. In the second part of the paper noted IIb, we start from the system of differential equations, which characterizes the real system with 13 degrees of freedom, of the feet of the female operator, which is integrated through Matlab and is graphically represented with the mechanical characteristics of the female operator, considered a right-handed user
