Conversion of Lehr's Damping into Rayleigh Damping

Product Feature

This article was translated by Google Translator View original text

Calculation in consideration of a damping (Lehr's damping as well) is not possible in the direct time step integrations. Instead, the Rayleigh damping coefficients are specified by the user.

In technical literature, the given damping for specific construction forms is in many cases only a rough approximation of the real damping ratios. In RF-/DYNAM Pro - Forced Vibrations, it is possible to use the damping value to determine the Rayleigh damping. This may occur at one or two natural angular frequencies defined by the user.
