Frequency response function as used in structural dynamics.
Project description
Frequency response function as used in structural dynamics.
For more information check out the showcase examples and see documentation.
Basic pyFRF usage:
Make an instance of FRF class:
a = pyFRF.FRF(
sampling_freq,
exc=None,
resp=None,
exc_type='f', resp_type='a',
window='none',
weighting='linear',
fft_len=None,
nperseg=None,
noverlap=None,
archive_time_data=False,
frf_type='H1',
copy=True
)Adding data:
We can add the excitation and response data at the beginning through exc and resp arguments, otherwise, the excitation and response data can be added later via add_data() method:
a.add_data(exc, resp)Computing FRF:
Preferable way to get the frequency response functions is via get_FRF() method:
frf = a.get_FRF(type="default", form="receptance")We can also directly get the requested FRF via other methods: get_H1(), get_H2(), get_Hv() and, get_ods_frf():
H1 = a.get_H1()
H2 = a.get_H2()
Hv = a.get_Hv()
ods_frf = a.get_ods_frf()
