Six-degree-of-freedom pool trial trip instrument suitable for submerged body icebreaking research

Abstract

The invention discloses a six-degree-of-freedom pool trial trip instrument suitable for submerged body icebreaking research. The trial trip instrument mainly comprises 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 are cooperated and matched, so that a submerged body can generatethe six-degree-of-freedom combined movement of surging, swaying, heaving, rolling, pitching and yawing; and the waveform monitoring mechanism is used for recording the ice layer bending deformation response excited when the submerged body moves at different combination degrees of freedom. According to the ice pool trial trip instrument provided by the invention, the motion state of the submerged body in a pool can be flexibly adjusted according to the experimental research requirements, so that the ice breaking efficiency of the submerged body in different motion states is explored, and the data support is provided for the ice breaking and water discharging operation of the submerged body.

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...
