摘要

The three dimensional natural frequencies, periods of vibration and modal configurations of elastic cables of arbitrary configurations are obtained and tables are presented which permit the determination of the natural periods for the first 48 modes of vibration of cables of any size and uniform mass distribution. The effect of altering the cable's extensibility modulus is considered and the tables are developed for two conditions of cable support; rigidly supported at each end, and free to more at the upper end in heave.
