Noise and vibration minimizing in machines threated as multi-sources system

摘要

Minimizing of noise at the operator's cage of engineering machines with complex structure requires the location and the identification of sources. The work is a direct continuation of the study on modelling of the acoustical structure of engineering machines that was presented at the WESTPRAC'94 and Inter Noise '97 Conferences, and is based on the extensive empirical material regarding vibration and noise in hydraulic excavators working in the most severe operating conditions (strip pits, quarries, etc.)
