英文摘要： The main objective of this work is to propose the integrated design theory and method to build the accurate multi-domain unified model for performing the design, analysis, optimization, and performance evaluation of the feed drive systems in machine tool, aiming at developing high-speed/precision feed drive systems. A systematic research plan involving in three aspects is as follows. Firstly, the research work will be centered on the movable joint characterizing and accurate performance modeling, namely, to get an insight for the dynamic characteristics and system coupling of the ball screw mechanism and the linear rolling guide joint surface. Secondly, the free vibration characteristic of the time-varying rotor-screw feed drive system will be analysized to design some adaptive notch filters that are based on gain scheduling to compensate the torsion vibration of first two orders, so as to accurately model servo control system to realize high speed/precision CNC feed movement. Thirdly，the modeling and optimization which takes into account the interaction among mechanical device, electrical subsystem, control subsystem and heat transfer parts will be studied in detail，as a result, the special multi-domain model library for modeling feed system will be extended. The unified multi-domain simulation model of feed dr
