Optimization of Design Information Decoupling of Kinematic Machinery Based on Meta-Action Theory

摘要

In the late stages of concept design of mechanical product is usually based on sequential design, but the interaction among different performances is ignored. Once defects are generated in the design process, it will be difficult to make up in the subsequent design and cause a constant waste of energy during entire production cycle. In view of this defect and combined with the main characteristics of the motion machinery, we firstly propose the framework of soft decoupling technology for motion machinery's design process is proposed. Secondly, coupling characteristics among the meta-action units are analyzed and the coupling constraint model is constructed. Then we reduce iteration and feedback of the design process information through reducing the information interaction among the aggregation sets of the units to reach the purpose of soft decoupling. Finally, the analysis results demonstrate that the meta-action design units decoupling technology is successfully applied to the design of pallet exchange frame motion scheme, which shortens the product development cycle and provides a beneficial reference for the design of motion-dominated mechanical system.
