Abstract
The subject of the study are vibration and mechanical noise at the operator from operating a laboratory washing machine. The source of vibration and noise are vibrations machine rotor when it rotates in a water bath. Vibrations of the rotor vary harmonically. The purpose of research - to assess the impact on the level of vibration of certain structural measures: the use of PTFE sliding bearings, elastic inserts and elastic supports, designed for short-run production. It was established experimentally that in the aggregate it possible to reduce the level of vibration in the workplace at 35 dB. In addition, the analytical calculations confirmed that the frequency of forced oscillations of the moving parts of the machine, in this arrangement, the greater the frequency of natural oscillations, whereby the occurrence of resonance is eliminated. These measures have improved consumer properties of the machine.
