FreeSRS
| Info Download |
The
new version of FreeSRS
was extented by a C++ library, which was added to the small
library of Python
and
Fortran77 files. FreeSRS
calculates the shock response spectrum (SRS) of an acceleration signal.
The algorithm used is from David O. Smallwood, see An improved recursive
formula for
calculating shock reponse spectra.
Shock and Vibration Bulletin,
No. 51, May 1981. The program is very fast, time-critical parts are written in Fortran 77, which is linked to Python by f2py. All spectra in the time and the frequency domain are accessible to the user in the Python environment. This allows easy analysis of all kinds of SRS, i.e. positive, negative or primary and residual SRS. An example how to apply the library is given in the download section. There might be bugs.
