Research On Performance Design And Optimization For Binding Machine

Product is a certain system which is made of several subsystems. The product's quality is determined by the performance of the system and whether the capability is good or not is determined by the design. In the cause of design, different performance, subsystems and parameters are coupling to form a really complicated network with fuzziness and dynamic as its characters. Therefore, studies on the product's performance and the effective ways for collaborative optimization of system have some value in theory research and engineer application.With binding machine as its target, this dissertation is about the design theory for performance optimization, the course for optimization design and the algorithm for collaborative optimization of coupling subsystems is defined which helps to greatly upgrade the entire performance of the binding machine. Main work are as follows:1. By analysis for the development of binding machine and the study status home and abroad of the optimization technology, the contents of the study and the scheme of the optimal design for binding machine unit is given.2. By studying on the full performance optimization modeling for the product and the theory of collaborative optimization. A concrete sample is operated successfully on the iSIGHT platform which provide basis for later study on the collaborative optimization way based on the systematic performance. Besides, the collaborative optimization way and various kinds of strategy performance optimization are put forward.3. According to the unique work performance and structure character of punching blade, a robust design methodology combining design of experiment (DOE),Kriging model technique and the strategy of optimization combination embodied in iSIGHT software are investigated for the design optimization. It guarantees the performance of punching whiling giving attention to the safety.4. Guided by the design demand for the systematic performance of the binding machine, a curve on comfort is put forward, which is based on the theory of human engineering. The subsystems are designed with the aim of safe work, delightful operation and close structure and the collaborative optimization mathematical model based on systematic performance is built on the study of the coupling relation of parameters in different subsystems. Finally, by setting up coherence restriction, the automation of solution is realized. The result shows that the force for punching reduces by 27.4%, the max acting force of human reduces by 50.9% and meanwhile, the developing trend of the acting force of human with the travel of punching conforms with the expect.5. Aim at the supporting module, integration with iSIGHT and Ansys is adopted, for the precise mathematical model is hard to establish with the irregular structure. After optimization, the bulk (quality) of ban is reduced by 19.8% whiling conforming to the intension and stiffness demand. And the fact that the opitimized ban's bending won't affect the performance of binding machine is verified after the analysis and calculation on the holes displacement. Finally, based on the optimization result of the entire machine, the change cause of stress and flexivity during punching is studied and a brief analysis on fatigue is is rendered which will lay the basis for the reliability study of an entire machine in the future.
