ST7-R3.10.20.2 Harmonic Response Analysis
This Webnote introduces the Natural Frequency and Harmonic Response solvers together with some basic concepts in modal analysis. This is done with reference to a simple cantilever beam model, which is harmonically excited at its free 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 benefits of the modal approach for this type of problem.
