Vibrace kabin zemních strojů

Abstract

This bachelor work deals with applications of non-dismantling diagnostics, specifically vibration diagnostics and acoustic diagnostics for earthmoving machinery 323 D manufactured by Caterpillar. In introductive theoretical part of work there are described the main terms of this area and the constructions of cabins as well. In practical part was performed measurement of vibration effective values, frequency spectrums and start-ups at certain spots of earthmoving machinery. Then the instrumentation, methodics and measurement evaluation are described. The goal of this bachelor work is finding out machinery’s behaviour and machinery comparing, specifically frame, counterweight, and cabin comparing and finding out noise level in cabin based on described non-dismantling diagnostic methods.
