Mechanical Design of Scientific Instrument Interface Module in Seafloor Observation System

Abstract

It has a far-reaching significance of developing and utilizing the marine resources to improve the human environment and alleviate the shortage of resources for the rich mineral, biological, oil and gas resources provided by the ocean. Undersea observation techniques, as an vital path to understand the ocean and exploit the ocean resource, play a more and more extensive influence in and around the world via its real-time, in-situ and 3-dimentional observing features. As an important part of the seafloor observation systems, SIIM serves as a bridge to connect the instruments and junction box. It requires that SIIM must have the ability to endure the high pressure, corrosion and organism attachment, and to ensure its modules work well. This paper aims to introduce a method of designing mechanical structure of SIIM. Finally, the reliability of the design is verified by means of the finite element analysis.
