摘　　要：以苜邦9KF-8042型方草捆压捆机为研究对象,采用SolidW orks建立D型打结器及其辅助机构的3D装配模型,导入ADAMS软件后对送绳、拨绳、搭绳、夹绳、绕绳、咬绳、割绳、脱扣等捆扎打结过程进行运动学仿真和时序分析,揭示了D型打结器的成结原理。样机试验表明,反求的D型打结器及其辅助机构模型准确,运动仿真正确再现了捆扎打结要求的预定动作过程,根据运动仿真结果确定了各构件耦合动作时序关系。The Mubang 9KF-8042 baler for square straw bale was chosen as research object.3-D assemble model of D-knotter and its ancillary mechanisms were firstly built up by using SolidWorks software,and imported to ADAMS software for its kinematics simulation and time series analysis of enlacing and knotting process,including sending rope,pushing rope,hanging rope,holding rope,winding rope,biting rope,cutting rope and threading off knot.Knotting principle of D-knotter was revealed.Motion test of the physical prototype showed that reverse designed model of D-knotter and its ancillary mechanisms were accurate,and the results of kinematics simulation recurred the predetermined motion processes of enlacing and knotting requirement correctly.According to the results of kinematics simulation,coupling relationship of motion time series of each functional component was determined.
