| 摘 要： | 采用三维势流理论计算不规则波中移动式栈桥码头拼接时两浮箱的运动响应，其中考虑了多浮体之间相互作用的影响而后计算出两模块上连接器之间的相对运动，最终找到浮箱拼装的最佳状态，为浮箱的拼装作业提供了；住确的依据在理论计算两浮体不规则波浪中相对运动的基础上，使用Visual Fortran编程语言结合OpenGL（open graphics library）图形接口技术，开发了一套两浮体相对运动仿真的软件系统，具有良好的交互性和效果的逼真性．其中，静水波面的绘制采用无限插值理论，并且利用三维势流理论求解波面升高模拟波浪运动．

| Abstract: | The motion response of two floating bodies in irregular waves is calculated by means of three-dimensional(3-D) potential flow theoryi,n consideration of their coupling influence.Then the relative motion of two connections on the mod-ules is computed to find the optimal status for connecting,which provides exact basis for floating bodies connecting.On the basis of the computation of the relative motion of two floating bodies in irregular waves,a suit of realistic representations software,which is of fully interactive and realistic effect,was programmed with Visual Fortran programming language and OpenGL(open graphics library)to simulate the relative motion of two floating bodies.The transfinite interpolation scheme is employed for the mesh generating of the free surface,and surface elevation is calculated by 3-D potential flow theory to simulate the wave motion. |
