Abstract

Sposób pomiaru hałasu i wykrywania źródeł dźwięku podczas diagnozowania uszkodzeń pojazdów na stanowiskach stacjonarnych polega na tym, że badany pojazd ustawia się jedną osią na stanowisku typu szarpak (10) lub stanowisku rolkowym (11), następnie rejestruje się równocześnie chwilowe poziomy dźwięku oraz obraz za pomocą układu mikrofonów (2) i kamer (3) zamocowanych do wózka z ramą pomiarową (1), które przemieszczają się wzdłuż podwozia badanego pojazdu, po czym sygnały akustyczne skanowanego podwozia badanego pojazdu oraz zarejestrowany obraz przesyłane są równocześnie do układu sterująco-pomiarowo-rejestrującego (7), przy czym zarejestrowany wyświetlany jest w czasie rzeczywistym na wyświetlaczu (8) w formie przetworzonej lub nie przetworzonej, ze wskazaniem miejsca występowania źródeł hałasu na tle obrazu podwozia badanego pojazdu. Urządzenie do pomiaru hałasu i wykrywania źródeł dźwięku podczas diagnozowania uszkodzeń pojazdów na stanowiskach stacjonarnych charakteryzuje się tym, że  składa się z ramy wózka z ramą pomiarową (1), na której osadzone są co najmniej 3 rzędy mikrofonów (2), przy czym w każdym rzędzie znajdują się co najmniej 3 mikrofony (2) oraz co najmniej 3 rzędy kamer (3), przy czym w każdym rzędzie znajdują się co najmniej 3 kamery (3), układu pozycjonująco-przesuwnego (4) do przemieszczania z ramą pomiarową (1) względem pojazdu w granicach  skrajnych obszarów przesuwu (4.1) i (4.2), liniowego napędu zębatkowego z przekładnią planetarną (6) odpowiadającego za przesuw wózka z ramą pomiarową układu sterująco-pomiarowo-rejestrującego (7), wyświetlacza stacjonarnego i/lub przenośnego (8) oraz głośnika (9).The method of measuring noise and detecting sound sources when diagnosing vehicle damage at stationary stations is that the tested vehicle is positioned with one axis on a tug-type station (10) or a roller station (11), then momentary sound levels and images are simultaneously recorded using a system of microphones (2) and cameras (3) attached to a trolley with a measuring frame (1), which move along the chassis of the tested vehicle, after which the acoustic signals of the scanned chassis of the tested vehicle and the recorded image are simultaneously sent to the control, measurement and recording system ( 7), and the recorded information is displayed in real time on the display (8) in processed or unprocessed form, indicating the location of the noise sources against the background of the image of the chassis of the tested vehicle. The device for measuring noise and detecting sound sources when diagnosing vehicle damage at stationary stations is characterized by the fact that it consists of a trolley frame with a measuring frame (1) on which at least 3 rows of microphones (2) are mounted, in each row there are at least 3 microphones (2) and at least 3 rows of cameras (3), with each row having at least 3 cameras (3), a positioning and sliding system (4) for moving with the measuring frame (1) relative to vehicle within the limits of the extreme travel areas (4.1) and (4.2), a linear rack and pinion drive with a planetary gear (6) responsible for moving the trolley with the measuring frame of the control, measurement and recording system (7), a stationary and/or portable display (8) and loudspeaker (9).
