摘　　要：运用刚体运动学原理与集中质量方法,建立双体组合式网箱浮架、网衣、锚绳及浮子的受力运动方程数学模型,利用物理模型试验对数学模型进行了验证,结果表明,本数学模型具有较好的可靠性和准确性。运用数字模型,计算了在不同流速条件下,双体组合式网箱锚绳受力、浮架运动及网衣变形。Based on rigid kinematics theory and lumped mass method,a mathematical model of the two cages of grid mooring system under current is developed by setting up the motion equations of floating system,net system,mooring system and floaters.In order to verify the mathematical model,a series of physical model tests have been carried out.According to the comparisons between simulated and experimental results,it can be that our mathematical model has better reliability and accuracy.Then,the forces on the mooring lines,the floating collar movement and net deformation were calculated under different current conditions.
