浮动基多机协调吊运系统的动力学建模与仿真
Dynamic modeling and simulation of a floating multi-robot coordinated towing system
摘要
Abstract
At present,cranes used at sea are insufficient in terms of their carrying capacity and working space.Therefore,a floating multirobot coordinated towing system is proposed in this study to make up for the demand for offshore towing.First,we set up the spatial configuration of the system according to the towing task,after which we established the kinematics equations of the system using the D-H coordinate transformation method.Then,we built the dynamics model of the towing system and floating foundation based on the theories of rigid dynamics and hydrodynamics.Using the kinematics equation of the system,we analyzed the positive and inverse dynamics of the system,after which we performed the time-domain simulation of the system.The results indicate that the load will have a great impact on the floating foundation motion with the initial excitation of load motion and floating foundation motion and that the floating foundation motion will also consume the kinetic energy of the load.Both results can affect the safety of offshore towing operations.Therefore,the antiswing control of the load and the stability of the floating foundation must be studied after dynamics analysis.关键词
