Identification of characteristic frequencies of damaged railway tracks using field hammer test measurements
FRF-based method can be used to identify characteristic frequencies of damaged tracks. Variability of field hammer test measurements in railway tracks is negligible. We present a method to define a statistically representative baseline of railway tracks. Cracks in the rail and the condition of fastening affect growth process of squats. Identified frequencies for squats by FRF-based method and ABA system largely agree.
