| 摘 要： | 给出舰船结构水弹性分析的通用公式,分析典型高速船的水弹性响应,将总响应分为线性和非线性,前者用线性势流理论计算,后者用船体—流体系统脉冲响应函数的卷积积分和水动力非线性修正得到。计算表明线性解答过高地估计了共振点刚体运动,从而导致弯矩预报不准确,而非线性模拟的中拱/垂弯矩均与实验吻合较好。

| Abstract: | Hydroelasticity analysis formula of ship structure is presented.Hydroelasticity response of a representative high speed ship is analysed.Overall response is devided into linear and nonlinear ones.The former is calculated with linear potential fluid theory and the latter is obtained by hull-fluid system impulse response function wrap integral and hydrodynamic nonlinear modification.Calculation shows that linear solution overestimates rigid body movement near resonance point,thereby bringing on unallowable be... |
