造波机主动消波系统现状与发展趋势

Current Situation and Development Trend of Active Absorption Wave-Making System for Wavemaker

在海洋工程领域中,常采用在水池或水槽等设施中进行物理模型试验的方法研究问题。在试验中造波机是实现造波模拟的核心基础装备,但在造波过程中,往往会产生二次反射,这对于试验是非常不利的,因此我们需要消除反射波,消波方法有两种——被动消波和主动消波,目前主动消波成为消波技术中的主流。在综合分析国内外试验水池与造波技术的现状的基础上,结合工程实际的需要,指出现有的主动消波方法存在的问题,总结造波机的消波技术。

In the field of marine engineering, people often use the method of physical model test to research in basin or tank. In the experiments, wavemaker is the core of the realization of wave simulation based equipment, but the wave-making system tends to produce secondary reflection that is ad-verse for experiments. So the reflected wave needs to be absorbed. There are two kinds of wave absorption methods—passive and active wave absorption. At present active wave absorption be-comes the mainstream in the wave absorption technique. On the basis of comprehensive analysis of the present situation of domestic and international test basin and wave-making technology, combined with the needs of engineering practice, this paper points out the existing problems of active wave absorption method, and summarizes the wave absorption technique of wavemaker.
