The invention relates to the technical field of hydrodynamic experimental researches, in particular to a vertical multi-plate wave maker. The vertical multi-plate wave maker comprises a water tank, a hydraulic station, a computer control system, a support, an actuator and a wave-making plate, wherein the hydraulic station is arranged on the water tank; the computer control system is used for generating nolinear wave control signals; the actuator is connected with the support; the wave-making plate is hinged with the actuator; the computer control system is electrically connected with the hydraulic station; the hydraulic station is connected with an actuator; the actuator is used for driving the wave-making plate to perform reciprocating motion; and the wave-making plate is formed by hinging a plurality of independent wave-making plates. According to the vertical multi-plate wave maker, vertical speed distribution can be accurately input, waves which are more complex and more variable than those produced by a vertical single-plate wave maker can be produced, and the wave-making accuracy is improved; an embedded system, a programmable logic controller or an industrial personal computer can be selected as a computer control unit, and the quantity and the size of required split plates are selected according to different application requirements of control accuracy, response speed, stability and the like; and on the premise that high accuracy and high response speed are guaranteed, the flexibility and the stability of system operation are enhanced, and the repairing and maintenance costs are reduced.

Description

technical field [0001] The invention relates to the technical field of hydrodynamic experiment research, and more specifically, relates to a wave generator for generating high-precision regular waves, irregular waves, internal waves and internal solitary waves in a water tank or a pool. Background technique [0002] In the field of ocean engineering and hydrodynamic testing, the wave maker is an essential device for physical model testing. The wave maker is usually set at one end of the test tank or pool, and waves are created by the reciprocating motion of the wave-making plate. Due to the complexity and diversity of experimental research, it is often required that wave generators can accurately generate waves that meet specific conditions. Most of the existing wave-making technologies in the vertical direction use a single plate to push back and forth flatly or swing, and the form of the vertical velocity distribution is fixed, or the swing type vertical linear velocity d...
