In order to accurately analyze the structural characteristics of a composite parallel machine tool, a new structural response modelling approach is proposed in this paper. A system dynamics model of the novel composite parallel machining machine platform is established by using the generality of the Jacobian matrix. Based on the mechanical characteristics, a structural stress identification index is presented to reflect the structural response of the composite parallel machining machine platform. Based on the prototype of the parallel robot platform, numerical examples are presented and some performances of the structural response characteristics have been fully discussed. The proposed mathematical model and structural identification index can provide a convenient method for structural optimization of composite parallel machining platforms.
