Abstract

We present on approach for the dynamic analysis of parallel manipulators which 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, a numerical example is given in order to illustrate the numerical aspects of the algorithms.
