Pyrotechnic devices are used to separate substructures from main structures.
Pyroshock can cause failure in electronic components that are sensitive to high frequency shock.
Most of the existing methods to analyze pyroshock have limitations for high frequency simulations and are only available for simulation of point explosive-induced pyroshock.
To solve the problem of existing methods, we developed a laser shock-based pyroshock reconstruction algorithm covering high frequency range that can predict linear explosive-induced pyroshock, as well as point explosive-induced ones.
The developed algorithm reconstructs pyroshock from laser shock test in both temporal and spectral domains using an iterative signal decomposition and synthesis method.
In the signal decomposition and synthesis process, unremoved signals in the stopbands occurred and were compensated by iteration to improve the results.
At the end of this paper, various types of pyroshock were processed through the proposed method.
Pyroshock wave propagation images and shock response spectrum images were presented as a result.
To verify the algorithm, we compared the obtained result with a real pyroshock.
The time domain signal was reconstructed with an averaged peak to peak acceleration difference of 20.21%, and the shock response spectrum was reconstructed with an average mean acceleration difference of 25.86%.
