摘要：
To realize efficient manufacturing and quick assembling of the arc-shaped aeronautic structural component with large scale, a hybrid flexible manufacturing system consisting of a double circumferential guideway and two parallel kinematic machine (PKM) modules is proposed. A conceptual design of the flexible manufacturing system is carried out with the virtual prototype technology, a kinematic model is established to conduct an inverse kinematic description, and the singularity of the PKM is analyzed. Then the reachable workspace of the system is predicted by using a 'sliced partition' searching algorithm, and an elasto-static model is developed to calculate the gravity-caused elastic displacements of the system by the substructure synthesis technique. The results are validated by numerical simulations on ANSYS Workbench. An index of average displacement is suggested to evaluate the influence of configuration parameter on the system elasto-static performance throughout the entire reachable workspace. The investigations manifest that the flexible manufacturing system claims the merits of a large workspace generated by the serial mechanism and high rigidity and loading capacity coming from the PKM module. The gravity-caused structural deformations must be paid enough attentions during the design stage of the flexible manufacturing system. Additionally, to facilitate its applications, the designers must enhance the bending resistance along x-direction and torsion resistance about y-direction of the hybrid flexible manufacturing system. © 2019, Editorial Office of Journal of Xi'an Jiaotong University.
