1. A method for determining a natural frequency of a structure,
the method comprising:
modeling the structure;
creating a synthesized sum of sines excitation comprising all possible sinusoidal waves within a defined range of frequencies;
applying the synthesized sum of sines excitation to a base of the modeled structure; and
generating response data indicative of a natural frequency of the modeled structure that is based upon the application of the synthesized sum of sines excitation.
