Study On Application Technology And Multi-domain Modeling For Electromechanical System

Since high-precision,high-speed and high-efficiency had been the developing orientation of advanced CNC,the CNC dynamic characteristics of electromechanical system were also evolving to meet a higher standard requirement.Multi-domain modeling and co-simulation for electromechanical systems was discussed in this thesis.To solve low efficiency and accuracy problems,the procedure for modeling was simplified,provided with a simulation model for engineers.And also a multi-function platform,as a complex electromechanical system required many engineers from different areas,was demanded to meet designers’ requirements so that scholars were able to completed project development.A typical feed system and a new method for multi-domaining modeling for electromechanical systems were put forward in this thesis,in which a modeling process for servomotor and feed system were also provided.Besides,a feed system platform was suscessfully established.The details were as follows:Firstly,the driving mechanism and dynamic performance of the feed system were evaluted.Key parts were seleted and the feed system platform was set up by researchers.Modal analyses and harmonic response analyses of the feed system platform were carried out.The stability of the platform was verified.Secondly,in this study,the theory of Multi-domain physical Modeling was elaborated and the design flow was recounted by researchers based on SolidWorks and Matlab.The installation of SimMechanics-link plug was summarized.Furthermore,the transfer function of servomotor was calculated and the stability for system controlling models was analyzed.A physical simulation model of Kollmorgen servo motor was built as well to carried out simple experiments.Finally,the method was applied into high-precision machine tools.Researchers calculated the kinetic equation and set up a dynamic model of feedback system.The feed system of TX1600G was established in MATLAB.In addition,this thesis analyzed controlling signals after the feed system platform was simulated.An experiment of the feed system platform was also described in the thesis.The platform combined CompactRIO with PC in LabVIEW and could be provided as an important basis for other similar researches.
