Gubenko N. The deterioration of vibroacoustics activity of line source in noise foundation.

3The object of research: noise source and ways in spreading of vibroacoustics vibrations from source into the environment The aim of research: includes the fall of vibration and noise loading, influenced all tram traffic participants (drivers, conductors, passengers). The methods of research and apparatus: analytic, based on using of vibration theory, experimental with using the theory of experiment planning, tenzometric forempiric appraisual of vibration process,vibroacoustic, experimental theoretic, based on mathematic and physics modeling of processes, tenzosensors, accelerometers, tenzosystems, tenzoamplifier‘Topaz - 10’, osulating detector N = 700, impulse threeoctave noisemeasurer .00023, analizator in real time scale 01012 with oscilating indicator SG - 1, selfwritten measurer 02060. Theoretic and practical results: mathematic models,vertical and rotating vibrations and post technical diagnostic of defects on surface of wheel running. were created. The novelty of research: post technical diagnostic of defects on surface trams wheel running was proposed to put into the operation, elastic tram cardan shaft was planned to put into operation in Kharkiv trams work. The degree of introduction: in Octyabrskiy trams work, at the railway SE ”Ukrspetcvagon”. The sphere of application: enterprises, exploited trams and railway rolling stock.
