Low-resistance trolley for researching performance of wave glider

Abstract

The invention discloses a low-resistance trolley for researching the performance of a wave glider, and relates to the field of naval architecture and ocean engineering. The low-resistance trolley comprises guide rails, a trailer carrier, an aluminum plate and heaving excitation control equipment. The guide rails are arranged above the side walls of a water channel. The trailer carrier comprises atrailer frame, wheel frames and wheels. The guide rails are located below the two sides of the trailer carrier. The aluminum plate is located above the trailer carrier. The heaving excitation controlequipment comprises a servo motor, a speed reducer, a winding wheel and a servo motor controller, wherein the heaving excitation control equipment is located above the aluminum plate. By improving theprior art, on the basis of fully achieving existing functions, cooperative design of the guide rails and the water channel is adopted, the problem that the test precision of existing equipment is nothigh due to the influence of the wall faces of the water channel is greatly solved, meanwhile, cooperative design of guide rail protrusions and the wheels is adopted, the trolley is transversely positioned, the structure is simplified, and a certain effect is also achieved for reducing the operating resistance of the trolley.

Description

technical field [0001] The invention relates to the field of ships and marine engineering, in particular to a small resistance trolley used for researching the performance of a wave glider. Background technique [0002] At present, the hydrodynamic performance tests of ships and ocean engineering structures mainly rely on pools and tanks, which can meet the hydrodynamic and noise test requirements of most traditional ships and ocean engineering facilities and structures. Simulate actual conditions. The wave glider is composed of a surface mother ship and an underwater glider. It is difficult to simulate the interaction between the two parts in the actual situation by directly using the whole machine to conduct experiments in the tank. Moreover, limited to the difference between flume wave making and ocean navigation waves, heave excitation equipment is needed to provide the heave effect to the underwater glider alone. [0003] Most of the side walls of the experimental wat...

Problems solved by technology

[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that the existing heave excitation test equipment used to study the motion performance of the wave glider, due to the influence of the wall surface of the water tank, the running resistance of the equipment is large and the operation is not stable. , resulting in low test accuracy for testing the performance of the wave glider with heave excitation equipment
