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)
