Modular Design of Typical Rigid Links in Parallel Kinematic Machines: Classification and Topology Optimization
Due to the demand of reconfigurable system in parallel kinematic machines (PKMs), modular design technology is significant and necessary. However, the core joint modules have been concerned about by earlier research rather than the customized link modules. This paper studies the modular design from the point of designing optimal structures of the rigid links with best mechanical performances. This process consists of two steps: classification and optimization. Firstly, a brief introduction outlines the current research status of modular design in PKMs and explains the aims of this paper. We next describe how the rigid links are classified and propose the technology of topology optimization to the classified links. Finally, calculation models for each group of rigid links are set up and their optimal structures are obtained through topology optimization. The results provide useful references for engineering design.
