The invention provides an intelligent measuring and controlling device for ship oscillation experiment, comprising a rigid support formed by an upper truss structure and four pile legs disposed at thelower end of the upper truss structure. The center of the upper truss structure is provided with a laser positioning device and a stepping speed regulation motor. The output end of the stepping speedregulation motor is connected to a cylinder-shaped rotating roller. Each pile leg is provided with a connecting ring, and each connecting ring is provided with a cylinder-shaped slipping ring. Each cylinder-shaped slipping ring is fixedly provided with a rotating wheel having a locking mechanism. Four rotating wheels are disposed on the same plane, and are respectively connected to a ship model through a steel rope. Four driving belt mechanism are respectively disposed between the cylinder-shaped rotating roller and the four cylinder-shaped sliding rings, and are disposed from top to bottom in a staggering manner. The invention is advantageous in that producing is facilitated; application is wide and operation is convenient; the measuring experiment result is more accurate, and the testing performance is better; the problem of measurement data errors due to limitation in traditional experiment methods and experimental facilities of a ship model towing tank can be resolved.
