摘要

本文从复杂圆柱形振荡浮子出发,基于线性波规则理论,考虑粘性阻尼吸取波浪能,建立了振荡浮子的一维运动方程,以此推导了振荡浮子在自由漂浮运动、无阻尼运动、恒定弹簧下有阻尼运动及最优弹簧和最优阻尼下和在设定工作状态下的振动表达式,最后实例分析了振荡浮子的振动特性。研究表明振荡浮子的固有周期是随入射波频率的变化而变化,对振荡浮子施加弹簧要依据波能装置的设计工作点来确定。

Abstract

Based on the linear wave theory and considering the viscous damper resistance absorbing the wave energy, the one-dimensional dynamics equation is formed for a complex cylinder acting as a wave energy conversion device. Expressions about the amplitude and velocity of the cylinder are deduced from the equation under the free movement (no a damper and no a spring), no damping movement with a invariable spring coefficient, the optimum damping movement with a invariable spring coefficient, the optimum damping movement with a optimum spring coefficient and the movement with a setting working point. Finally, Analytical results of oscillating property of the cylinder are given for some examples. Numerical calculation indicates that the natural frequency of the cylinder varies with the incident wave frequency and it should be according to the working point set whether the spring is selected.
