Modal Analysis of the Submarine Optronic Mast Under Hydrodynamics Effect

This article demonstrates the hydrodynamics analysis for the optronic mast in a complex marine application environment, and then derives the dynamics parameters of optronic mast. Based on this theoretical discussion, the finite element （FE） model of optronic mast is built, analyzed and solved with the help of computer. According to the results from FE model, this article also analyzes the static stress deformation and dynamic natural frequency and vibration mode under the complex hydrodynamics effect. In this way, it has proved the important basis for the optimization design of the optronic mast.
