英文摘要：

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.
