设计用于城市地铁工程Φ6.28 m土压平衡盾构配套使用的管片拼装机,并建立数字样机模型。通过对管片拼装机进行运动学和动力学仿真分析,获得了各驱动部件的动力学特性以及升降液压缸端部的受力情况,表明所设计的管片拼装机的机构运动原理合理,为动力系统的选型设计提供了依据,并为零部件的强度校核提供了边界条件,缩短了设计周期。 It is designed to be used in pipe fitting machine of Φ6.28 m earth pressure balance shield used in urban subway project and to build digital prototype model. Through the kinematics and dynamics simulation analysis of the pipe assembly machine, the dynamic characteristics of the driving components and the force of the end of the lifting cylinder are obtained, which shows that the principle of the mechanism of the pipe assembly machine is reasonable and is Power system design provides the basis for the selection, and components for the strength of the check provides a boundary condition, shortening the design cycle.
