Webnon-uniform beam modeshape is a weighted series sum of the (closed-form) uniform beam modeshapes. Only a few uniform beam modes are necessary to generate the non-uniform beam modeshape and a convergent hull girder frequency. Thus, the method is very effective in the low-frequency domain like ship-structure. Webof normal modes and normal coordinates. We then add on driving and damping forces and apply some results from Chapter 1. In Section 2.2 we move up a step and solve the analogous problem involving three masses. In Section 2.3 we solve the general problem involving N masses and show that the results reduce properly to the ones we already …
