Abstract
1
Summary: Possibilities of applying energetistic techniques to the measurement of complex vibroacoustic processes are presented using as an example a hydraulic feeder. These innovative research methods open up new prospects for the reduction of noise emission. The described vector techniques of locating sound sources by means of an acoustic probe and a measuring plane antenna deserve special attention. As a result of the measurement a distribution of the intensity of emissions originating from different parts of the source is obtained in the form of emission maps. The techniques can be applied to any object (e.g. a pump, a car, a motor) to determine the main sources of noise emission and then this information can be used to improve the object's design.
This paper is based on research in the fields of the design and operation of hydraulic systems, conducted for many years in the Institute of Machine Design and Operation at Wrocław University of Technology.
