本文提出了比较接近于实际的波箔的力学分析,并应用圆柱薄壳线性理论,导出了波箔变形的基本方程,从而求得了单波刚度和总刚度的计算公式。 In this paper, the mechanics analysis of wave-foil which is close to the actual one is put forward and the thin shell linear theory is applied to deduce the basic equation of the wave-foil deformation. The formula of the single-wave rigidity and the total stiffness is obtained.
