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.
