An Introduction to
Random Vibration. A random vibration
signal is analyzed in terms of its histogram, probability density function,
and descriptive statistics.


Power Spectral Density Units [ G^2 / Hz ]. The bandpass
filtering method is used to demonstrate a power spectral density
calculation.


Integration of the Power Spectral
Density Function:
The overall GRMS value is obtained by integration, for loglog format.


Introduction to the Shock Response Spectrum: A digital
recursive filtering relationship is developed from the convolution
integral.

Code

This program accepts an acceleration,
velocity, or displacement power spectral density function. Given one of
these functions, the program then integrates or differentiates as
appropriate to find the other two functions. The program also calculates
the overall level of each of the three functions.
