Abstract

The invention discloses a water tank active absorption type wave maker system and a control method, the system comprises a head end active absorption type wave maker, a tail end active absorption type wave maker, a reflectivity measuring device, a central servo controller and a computer, the head end and the tail end of a water tank are respectively provided with an active absorption type wave maker; and wave height sensors are arranged on the wave making plates at the two ends respectively and used for feeding back wave height data on the plates in real time, and a central servo controller is adopted to control servo motors at the two ends at the same time to drive the wave making plates to operate. According to the scheme, all operation data and feedback data are synchronously acquired and calculated, and high-precision wave simulation is carried out while high-performance wave absorption is realized. Meanwhile, by adopting the control method provided by the invention, high-efficiency reflected wave absorption can be realized, a wider wave spectrum range can be adapted, and the experimental use requirements of high simulation precision and large wave height in a short water tank are met.

Description

technical field [0001] The invention relates to a wave physical simulation system in the experimental fields of coastal engineering, marine engineering and ship engineering, and in particular to a water tank active absorption wave maker system and a control method. Background technique [0002] In the fields of coastal engineering, marine engineering and ship engineering, physical model experiments are an important means of researching problems. Researchers use the wave generator in the tank to generate waves, which act on model objects to study scientific and engineering problems under two-dimensional boundary conditions. Usually the wave maker is located at the head end of the tank, the end of the tank is equipped with a passive wave absorbing device, and the experimental model is located in the middle of the tank. When the reflectivity of the model object is high, secondary reflection waves will be generated between the model object and the wave generator, which will aff...
