基于波谱密度特性的海浪仿真研究

基于密闭液体的体积变化导致压力变化的特性，研制出了一种高响应、高精度的海浪仿真器，能够模拟海浪对任意水深处的影响作用。在保持微小频率段内总能量相等的条件下，通过规则波的合成，获得了描述已知波谱密度的海浪，并由海浪仿真器模拟出了任意水深处所受到的海浪作用，频谱分析表明模拟海浪具有与真实海浪相一致的波谱密度特性。

Study on wave simulator and realization based on properties of wave spectrum

A wave simulator with high response and precision has been developed based on the relationship between volume and pressure of contained liquid to simulate the influence of waves at any depth. The desired wave is obtained by synthesis of a series of regular waves basing the constant of total energy in a tiny spectrum section, and then inputted into the simulator to simulate the action of wave. Analysis of the simulated wave spectrum shows that the spectrum has the same properties as real wave.
