Time History Synthesis for Shaker Shock Testing

Consider a component which is to be subjected to a shock test using a shaker table.

The test specification for this example is a Shock Response Spectrum (SRS).

The control computer must synthesize a time history for the test.  The typical method is via a series of wavelets.

The Matlab scripts in wavelet_synth.zip demonstrate this process.

The main script is:  wavelet_synth.m

The remaining scripts are supporting functions.

Here is a Fortran version:  wavelet_synth.f

Here is a script that uses a series of sinusoids:  srs_sine_syn.zip
