Simulated sea wave generating device and method

Abstract

The invention discloses a simulated sea wave generating device and method. The device comprises an acoustic transducer, a motion control card, a subdivision driver, a stepping motor, a pull rope position sensor and a data acquisition card, wherein the acoustic transducer is fixed on a displacement system and can complete set movement and emit sound waves under the action of the displacement system, so that a preset wave effect is generated in a tide gauge well or a small water tank; the motion control card is connected to an upper computer, and the stepping motor drives the displacement systemto move; the pull rope position sensor is connected to the displacement system and is used for acquiring displacement information of the acoustic transducer; and the pull rope position sensor and theacoustic transducer are connected to the data acquisition card, and the data acquisition card is connected to the upper computer. According to the device and the method, waves with specific flow rates and shapes are simulated in the tide gauge well by the stepping motor, so that an effect of simulating sea waves in different states is achieved.

Description

technical field [0001] The invention relates to motor control and sea wave simulation technology, in particular to a device and method for simulating sea wave generation. Background technique [0002] With the development of our country's economy and the progress of the industrial level, the development and utilization of the ocean has become more and more extensive, and more and more experiments have been conducted using the marine environment. In view of the regional nature, complexity and economic problems of the marine environment, a lot of experiments have been wasted. With human and material resources, the research on simulating the marine environment came into being. The ocean is a rapidly changing and complex phenomenon of water movement. Generally speaking, the simulation of waves involves a wide range, and the law of wave fluctuations is very complicated. At the same time, seawater fluctuations may be affected and affected by various forces, such as gravity, wind f...

Problems solved by technology

There are many factors that affect waves. Even under the same conditions, the waves presented are not completely definite, and it is difficult to accurately describe them with a mathematical model. For this random phenomenon, it is necessary to find the wave at a certain time and a certain place. Specific eigenvalues ​​are impossible and meaningless

The increase in the accuracy of the mathematical model will also increase the complexity of the model, and will increase the difficulty of computer implementation.
