Абстракт: В тази работа е извършено експериментално изследване на акустичния шум, генериран от контакта колело-релса при преминаване на релсово превозно средство. Направени са измервания на нивата на звуково налягане при движение на влакове с постоянна скорост, както и е извършен честотен анализ на собствените затихващи трептения на релсови пътища от мрежата на НКЖИ и на колоос. Чрез числено моделиране са определени собствените честоти на колооста и релсовия път и са сравнени с честотния диапазон на шума. Резултатите са анализирани и са направени изводи относно честотните параметри на акустични абсорбери за този шум.

Abstract: An experimental study of the wheel/rail noise generation during the motion of a train is carried out in this paper. Measurements of the noise levels are recorded during the passing of the train with a constant velocity. The spectral analysis of the free vibrations of the railway and the wheel was made. Also, the natural frequencies are calculated using numerical models of the system. They are compared with the frequency of the noise response. The results will be used in the process of design of noise barriers and absorbers.
