NATFREQ users manual
This manual describes a computer program that has been developed to calculate natural frequencies and mode shapes of taut cables with attached masses and spring-mass combinations. The equations of motion are solved by an iterative technique allowing accurate calculation even for extremely high mode numbers. The approach has the advantages that it is fast, accurate, and can easily accommodate a variety of system configurations including bodies attached to the cable. This document covers the theory used in the development of the code. Line-by-line descriptions of both the input and output data are given, and several examples illustrating the use of the program are included. Some of the difficulties that may be encountered when running large, complex problems are discussed and possible solutions proposed. The structure of the program is described in moderate detail. The program is written in a style which makes additions or modifications easy to implement.
