PL Autorzy prezentują nową metodę diagnostyczną (in-vitro), wykorzystywaną w diagnostyce pojazdów samochodowych, polegającą na detekcji i pomiarze wartości drgań o charakterze wibroakustycznym. Wydaje się, że niesprawność układu recyrkulacji spalin nie powinna mieć wpływu na drgania, generowane przez s[...]
EN The authors presents a new in - vitro way of diagnosis in automotive vehicle which depend on detection and measure of vibroacustic vibrations of the diesel engine. It seems that the Exhaust Gas Recirculation circuit that does not work properly shouldn't have an influence on vibrations generated by a[...]

PL W artykule przedstawiono wyniki badań akustycznych barier drogowych, uzyskane z wykorzystaniem laserowego wibrometru dopplerowskiego i przetworzone z wykorzystaniem oprogramowania LMS, na przykładzie ekranu akustycznego zlokalizowanego przy drodze S1 na terenie Sosnowca. Eksperymentalną analizę moda[...]
EN In the paper, the results of tests and calculations are presented for acoustic road barrier treated as a plane vibrating surface source emitting acoustic waves. The tests were realized with the use of scanning Laser Doppler Vibrometer (LDV) which enables remote registration and the spectral analysis[...]
