摘要: 柔性宏刚性微机械臂是一类典型的刚柔混合机械臂系统。采用有限元法,以2F2R宏微机械臂为研究对象,通过分析,详细推导和建立具有普遍意义的动力学模型。基于给定关节空间运动轨迹,对2F2R宏微机械臂的结构参量、截面参量、材质、集中质量分布等与系统弹性振动尺度效应之间关系与变化规律进行分析。在此基础上,针对操作空间运动轨迹,采用宏微空间分解方法,进一步分析上述设计参量与系统弹性振动尺度效应之间关系。通过上述两方面研究工作,获得许多有参考价值的研究成果,这对于该类宏微机械臂的设计与控制都将具有重要意义。

Abstract: Flexible-macro rigid-micro manipulator is a typical series hybrid rigid flexible manipulator system. The finite element method is used to study the 2F2R macro micro manipulator. By detailed analysis, a dynamic model with general significance is derived and established. Based on the given joint space trajectory, the relationship and the change law of the structure parameters, the section parameters, the material, the lumped mass distribution of the 2F2R macro micro manipulator arm and the system elastic vibration scale effect are analyzed. On this basis, the macro micro space decomposition method is adopted to further analyze the relationship between the design parameters and the elastic vibration scale effect according to the motion trajectory of the operating space. Through the above two aspects of research work, a lot of valuable research results are obtained, which are of great significance to the design and control of this kind of macro micro manipulator arm.

Key words: 2F2R macro micro manipulator, dynamic model, elastic vibration, scale effect
