ST7-1.10.20.2 Harmonic Response Analysis
The aim of this Webnote is to introduce the Harmonic and Natural Frequency Solvers, and some basic concepts in modal analysis. This is done with reference to a very simple cantilever beam model, which is harmonically excited at its outboard end. Ways of introducing damping to the system in Strand7 are then demonstrated, and a comparison is made with a full system transient solution, highlighting the computational and conceptual benefits of the modal approach for this problem type. The harmonic...
