rrs

The rrs (Random Response Spectrum) is a standard mathematical function that is commonly used in random load analyses for space systems. The rrs is defined as the rms response of a 1-DOF system as a function of its natural frequency for a given damping ratio.

Syntax

rrs(input_x_vector, input_y_vector, damping_factor, safety_factor)

Arguments

input_x_vector
Input X vector of the random excitation spectrum curve.
input_y_vector
Input Y vector of the random excitation spectrum curve.
damping_factor
Damping ratio is calculated using the damping factor.
safety_factor
Safety factor against yield and rupture stress.

Example

rrs(p1w1c1.x,p1w1c1.y,25,1.2)
