A new approach for the dynamic analysis of parallel manipulators is presented in
this paper. This approach is based on the principle of virtual work. The
approach is firstly illustrated using a simple example, namely, a planar
four-bar linkage. Then, the dynamic analysis of a spatial six-degree-of-freedom
parallel manipulator with prismatic actuators (Gough–Stewart platform) is
performed. Finally,... hiện toàn bộ
A cable-driven parallel manipulator is a manipulator whose end-effector is
driven by a number of parallel cables instead of rigid links. Since cables
always have more flexibility than rigid links, a cable manipulator bears a
concern of possible vibration. Thus, investigation of vibration of cable
manipulators caused by cable flexibility is important for applications requiring
high system stiffness... hiện toàn bộ
