27-85 STUDIUL IMPEDANŢEI MECANICE A MODELULUI CORESPUNZĂTOR SISTEMULUI UMAN MÂNĂ-BRAŢ

STUDY OF MECHANICAL IMPEDANCE OF THE MODEL CORRESPONDING FOR HAND-ARM HUMAN SYSTEM
The present paper will be a presentation of one possible method of driving mechanical impedance determination. Exposure to harmful vibrations can lead to damages of the structures and health problems or disorders that can appear at the human body. The knowledge of the structures and human body mechanical impedance is essential for realizing appropriate administrative, technical and medical prevention measures.
Keywords: mechanical impedance, vibration, human hand-arm system

23-68 STUDIUL EXPERIMENTAL AL ACŢIUNII VIBRAŢIILOR MAŞINILOR-UNELTE PORTABILE ASUPRA SISTEMULUI UMAN MÂNĂ-BRAŢ

EXPERIMENTAL STUDY OF THE VIBRATION ACTION
OF PORTABLE MACHINE TOOL ON
THE HUMAN HAND-ARM SYSTEM
This paper is an experimental study about the importance o vibration
action acting on the human operator. For this study were made a series of
measurements on different parts of the hand-arm system of a human operator.
Were measured the vibrations generated by a hammer drill operating both idle
or full load.
Conclusions reguarding this measurements were then generated and
the results are presented in the paper below.
