Preliminary Research of Wave Direction Measurement Method Based on Pressure Difference Method
为解决波向测量误差大的问题,本文首次提出了一种基于压差法的波向测量新技术,根据海浪的运动变化规律,在这里巧妙地引进了压差技术,通过对放置在水下一个圆环上多个压力传感器同圆心点上的压差变化进行分析可以得出,圆环上不同方向上的压力传感器同圆心点上的压力传感器之间的差值及相位是随波浪方向变化而变化的,对圆环上不同方向上的压力传感器同圆心点上的压力传感器之间的差值进行分析,找出变化规律与波向的关系,以此得出真实的波向分布.本文通过波浪水池实验验证了该方法的可行性,并通过对实验数据的解析初步得出了压差变化规律与波向的变换关系.
In order to solve the problem of large error in wave direction measurement,a new technique of wave direction measurement based on the pressure difference method is proposed for the first time in this paper.According to the changing law of wave motion,the pressure difference technique is cleverly introduced here.By analyzing the variation of pressure difference between multiple pressure sensors placed on a circle underwater and one pressure sensor at the center of the circle,it can be concluded that the difference value and phase between them change with the wave direction.The difference between the pressure sensors on the circle in different directions and the pressure sensor on the center point of the circle is analyzed to find out the relationship between the variation pattern and the wave direction,so that the real wave direction distribution can be derived.The paper verifies the feasibility of the method through wave pool experiments,and initially derives the transformation relationship between the pres-sure difference variation law and the wave direction by analyzing the experimental data.
