| 摘 要： | 上海交通大学船舶流体力学研究室新近对导管架下水过程的理论计算和模型试验进行了开发性研究。文中采用直角坐标和Euler角描述导管架和驳船系统的空间状态,将约束方程的二次微分形式与动量(矩)方程联立,建立了下水过程的三维运动方程,用Runge-Kutta法求其数值解。文中选了一个二维运动的侧子进行计算,并与试验结果作了比较,符合程度良好。

| Abstract: | Theoretical calculations and model tests of jacket launching process has been carried out recently in the Ship and Ocean Engineering Hydrodynamics Laboratory of Shanghai Jaio Tong University. The ,spatial conditions of the jacket-barge system are described by using rectangular coordinates and Euler angles. Combining quadratic differentiation of restraints with momentum (moment) equations, three-dimensional equations of motion of the launching jacket are established, Numerical solutions are obtained by Runge-Kutta. method. In order to check the accuracy of the calculations presented in this paper, an example of two-dimensional motion is selected. From the comparison of the calculation results with some tests data, it is shown that the theoretical calculations are satisfactory. |
