Intelligent regulating device and regulating method for trimaran side body

Abstract

The invention discloses an intelligent regulating device and a regulating method for a trimaran side body. The intelligent regulating device for the trimaran side body comprises a lateral body horizontal position regulating device and a lateral body lengthwise position regulating device; the lateral body horizontal position regulating device comprises a connecting bridge front section, a connecting bridge rear section and a hydraulic device, wherein the front end portion of the connecting bridge front section is welded on the side body of the trimaran, and the middle rear portion of the connecting bridge front section stretches into a bearing hole of the middle front portion of the connecting bridge rear section; and the lateral body lengthwise position regulating device comprises a connecting bridge slide seat, a transmission screw rod and two driving motors, wherein the front end of the connecting bridge slide seat is fixed at the rear end of the connecting bridge rear section, and athreaded hole is formed in the rear portion of the connecting bridge slide seat through the transmission screw rod. According to the optimal position of the side body at different speeds, the navigational resistance of the trimaran is reduced by changing the telescopic distance of the connecting bridge front section; and according to the data such as pitch and heave of the trimaran at different speeds, the vessel generated waves of the trimaran are reduced by changing the position of the connecting bridge rear section in a guiding slide groove to change the lengthwise position of the side body.

Description

technical field [0001] The invention belongs to the technical field of trimarans, and in particular relates to an intelligent adjustment device and an adjustment method for a side body of a trimaran. Background technique [0002] The trimaran has excellent resistance performance when sailing at high speed, and has the advantages of large deck area, flexible general layout, excellent stability, good seakeeping and stealth, so it has broad application prospects. In recent years, the research and application of trimaran has gradually increased, and it has become one of the hot spots in the research of high-performance ships. It is one of the advantages of the high-speed trimaran to reduce the resistance during high-speed sailing through the beneficial interference of the trimaran main body and side hull. Both theory and experiments have shown that the layout of the side body has a great influence on the resistance performance of the trimaran, and the optimal layout of the side...

AI Technical Summary

Problems solved by technology

When factors such as side body layout, sheet body line, and overall layout are considered comprehensively, the problem will become more complicated

At present, most of the studies on the rapidity of high-speed trimarans focus on the influence of the side body layout on the ship's wave-making resistance and how to determine the optimal layout form of the side body under the premise of a single working condition; In actual operation, the types of tasks are relatively diverse, and there may be various working conditions. For a trimaran designed for a single working condition, in other working conditions, there may be a large interference resistance between the main hull and the hull. leading to poor resistance performance of the trimaran
