Finite-Element Models for NUSC Vibration Experiments on Thin-Line Towed-Array Modules.

Abstract

Finite-element models were developed for thin-line towed array modules. The modules that have been considered are a 15-ft hose strength member module, a 30-ft internal strength member module, and three different configurations for a 5-ft internal strength member module. The theoretical predictions of these models for impedence, transmissibility, longitudinal displacement and pressure level were compared to experimental measurements on these modules that were obtained at NUSC. Good agreement is obtained between the theoretical predictions and the experimental measurements. It is shown that the size of the spacer hole is an important parameter in determining the pressure level in an internal strength member module.
