rolland.postprocessing.TDR¶

class rolland.postprocessing.TDR(*, results, f_min=100.0, f_max=3000.0, tdr=numpy.array([]), filter=None, freq=numpy.array([]))[source]¶

Bases: RollandPP

Postprocessing class for TDR (Track-Decay-Rate).

This class calculates and stores the Track-Decay-Rate (TDR) based on [5].

Parameters:

results (Deflection)
f_min (float)
f_max (float)
tdr (ndarray)
filter (str | None)
freq (ndarray)

results¶

Instance of the Deflection class containing the results.

Type:: Deflection

tdr¶

Track-Decay-Rate vector \([dB/m]\).

Type:: numpy.ndarray

ind_tdr¶

Indices of the TDR points.

Type:: list[int]

x_tdr¶

Distances of the TDR points from the excitation point \([m]\).

Type:: numpy.ndarray

filter¶

Filter type (default is ‘1/3 Octave’).

Type:: str | None

freq¶

Frequency vector \([Hz]\).

Type:: numpy.ndarray

find_tdr_points()[source]¶: Find the corresponding measurement points depending on track type.

calculate_tdr()[source]¶: Calculate the Track-Decay-Rate (TDR) based on the results.
