Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] Such as figure 1 As shown, a non-reflection wave tank wave maker consists of an industrial computer, a PLC motion controller, and the first and second drivers to form a control module responsible for the state control of the entire wave maker system. The industrial computer includes two parts, the host and the LCD display. The host hardware description: Intel Core i3 dual-core four-thread processor, main frequency 3.3GHz, memory 4GB, running embedded Windows7 system, dual 100Mbps network interface. The industrial computer is used to run the upper computer program of the wave maker, including the functions of generating the motion control sequence corresponding to the target waveform, controlling the PLC program, detecting the running state of the motor, performing wave height spectrum analysis, and real-time display. The network communication between the industrial ...

Abstract

The invention belongs to the technical field of marine structure dynamic experiments, and relates to a reflection-free wave flume wave maker. The reflection-free wave flume wave maker comprises a control module, a transmission module, a data acquisition module and an absorption module, and is characterized in that the control module is responsible for general logic control for the system through a man-machine interface, the transmission module receives control instructions of the control module and performs corresponding control operations, the data acquisition module acquires the wave height in front of wave pushing plates of the wave maker in real time and feeds back the wave height to the absorption module, and the absorption module compares the feedback wave height with target wave height and converts the wave height into a wave making data sequence after being corrected by an absorption algorithm. The wave maker system can flexibly select a wave making mode, and normal wave making or reflection-free wave making is performed; and secondly, the wave maker can be configured flexibly, one-way wave making or two-way wave making is performed, and the wave making flexibility is improved. The reflection-free wave flume wave maker effectively improves the absorption wave making efficiency and can be widely applied to hydrodynamic physical model tests.

Description

technical field [0001] The invention relates to a wave maker for a non-reflection wave tank, which belongs to the technical field of marine structure dynamic experiments. Background technique [0002] As a kind of physical model experimental equipment, the non-reflection wave tank wave maker is mainly used in the fields of coastal engineering, ocean engineering and ship engineering. In the natural water environment, after the wave collides with other structures, the reflected wave is continuously attenuated in the open boundary until it disappears, and no secondary reflection occurs. In the wave tank, due to the limitation of the size of the tank, the reflected wave cannot be completely dissipated. After encountering the push wave plate, a secondary reflected wave will be generated, which will affect the accuracy and reliability of the model test. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the object of the present invention...
