Abstract

The invention provides a resistance testing device for a cable-towed ship model. The resistance testing device comprises a power part, a towing cable, a fixing part and a measuring and controlling part, wherein the power part comprises a support frame arranged on a dock pond wall, a motor, a rotating speed and torque measuring instrument and a driving wheel; the motor is connected with the rotating speed and torque measuring instrument through a primary shaft coupling; the rotating speed and torque measuring instrument is connected with the driving wheel through a secondary shaft coupling; the fixing part comprises a fixing frame and a driven wheel arranged on the fixing frame; the fixing frame is arranged on an end wall of a tow truck; the towing cable is wound on the driving wheel and the driven wheel respectively, so that towing of the ship model is realized; and the measuring and controlling part comprises a motor controller which is connected with the motor, a data acquisition unit which is connected with the rotating speed and torque measuring instrument, and a control computer. The resistance testing device has the characteristics of convenience in using and operating, easiness in producing, disassembling, assembling and maintaining, and the like, is suitable for ship model towing water ponds and various towing water grooves, and can be applied to ship model resistance testing of general engineering properties and ship resistance teaching experiments.

Description

technical field [0001] The invention relates to a resistance test device. Specifically, it is a ship model resistance test device. Background technique [0002] The purpose of the ship model resistance test is to obtain the relationship between the ship model resistance and the speed, calculate the resistance performance of the real ship, and predict the effective power required by the real ship at a specified speed. The most commonly used test method is the trailer towing type, that is, the ship model resistance measuring instruments and equipment are installed on the trailer during the test, and the trailer drives the ship model forward at a constant speed to measure the resistance of the water to the ship model. However, the trailer-type ship model resistance test method has a large test device, expensive equipment, complicated debugging, regular maintenance, high technical requirements for operation and use, and the close cooperation of laboratory personnel. The traile...
