The Study on Vibroacoustic Characteristics of Shunting Locomotive Cabin

Power plant of shunting locomotive is a powerful source of infrasound. If the level of infrasound is more than 100 dB, the time of operator work should be limited. The paper presents a simultaneous measurement of infrasound and low-frequency vibration at various modes and loads. The levels of infrasound and low-frequency vibration were measured inside the cabin and near the shunting locomotive. It was detected that infrasound depends on low-frequency vibration. There was a relationship between the level of infrasound and the opened window inside the cabin. Some recommendations to reduce the infrasound level were developed. The results indicate, overall, that the level of infrasound exceeds the standard values. The implementation of developed recommendation could reduce the level of infrasound.
