CNC Machine Linear Feed System Static And Dynamic Characteristics Analysis Technology Research And System Development

With the rapid development of information technology and network technology, the machinery manufacturing industry is undergoing a revolutionary change. The practical significance to improve product development efficiency and to reduce production costs put the digital design technology into the design and analysis process of the CNC machine tool feed systemBased on the analysis of the functional requirement and the performance requirement in the software system, the overall design of the system is proposed from the system structure, workflow, data flow diagrams and functional aspects. The thesis access to the feed system natural frequencies, corresponding mode shapes, the curves of the amplitude-frequency characteristic and the diagram of the stress strain in the feed system to identify the weaknesses of the feed system and to propose solutions, through the analysis of the system model, harmonic and stress strain to linear CNC machine tool feed system based on the two key technologies which are the application of finite element modeling based on the ANSYS secondary development and the static-dynamic analysis based on the joint surface properties. For example, the Y-feed system in Dalian machine tool VDL600E completes the static-dynamic analysis based on the joint surface properties based on the realization of the finite element model. System data Management was realized by describing the developing technology, and the database tables and table relationships of the system were designed detailed.Finally, Basing on the above research achievement, the sofeware system called FSA is developed by using APDL and C#, and the system running instance was gived at last.
