"Presented paper deals with an evaluation of measuring of vibrations on a bucket wheel excavator (BWE) SchRs 1320 during mining. Vibrations were measured on the BWE\u2019s upper steel structure by using of 28 accelerometers. Measured signals were associated with operating data from the BWE\u2019s central control computer. By connecting of these two signal groups a complete set of valuable data was obtained. This data set was analyzed by time-frequency transforms. This paper shows results for three selected time periods. Results proved frequency changes in vibrations of upper steel structure of the BWE during moving in mining process."@en . . .
