Input Files for Shock Impulses for Response Spectrum Analysis

CAE Associates has created a series of input files that will generate the response spectrum for the 3 common types of shock impulses.

Calcresp_halfsin.inp – Half-sine
Calcresp_saw.inp - Sawtooth
Calcresp_trap.inp - Trapezoidal

Make sure to edit the file to set up the inputs which describe the impulse load you have and the damping level you require. Then, run the file in ANSYS and it will generate a CSV file output of the response spectrum (Frequency vs. Acceleration).

The user should use their judgement to create an envelope from this data before using it in their response spectrum analysis.
