A six-degree-of-freedom tank navigator suitable for submerged ice-breaking research

Abstract

The invention discloses a six-degree-of-freedom water tank navigator suitable for submerged ice-breaking research. The navigator mainly includes three parts: a guide rod movement mechanism, a cam movement mechanism and a waveform monitoring mechanism, wherein the guide rod movement mechanism and the cam movement mechanism The cooperation between the two mechanisms enables the submersible to produce a six-degree-of-freedom combined motion of surge, sway, heave, roll, pitch and yaw. The waveform monitoring mechanism is used to record the bending deformation response of the ice layer excited when the submerged body moves with different combined degrees of freedom. The ice water pool test instrument provided by the present invention can flexibly adjust the motion state of the submersible in the pool according to the experimental research requirements, and then explore the ice-breaking efficiency of the submersible under different motion states, and provide data support for the submersible to break ice and discharge water.

Description

technical field [0001] The invention belongs to the design and manufacture technology of ships and marine engineering equipment, and in particular relates to a six-degree-of-freedom water tank navigator suitable for ice-breaking research on submerged bodies. Background technique [0002] As the global climate warms, the area and thickness of sea ice in the Arctic continue to shrink, and the exploitation of non-biological resources such as oil and gas in the polar regions and the opening and utilization of waterway resources are gradually becoming possible. In view of the increasingly prominent potential political, economic and military value of polar regions, this region has become a hotspot of international competition, attracting the attention of more and more polar and near-polar countries. As the core marine equipment for polar scientific research and development and utilization of polar resources, icebreaking methods and icebreaking capabilities have become the focus of...
