数控机床结合面特性分析与建模作为机床数字化设计开发的共性关键技术，对于准确预知产品性能、提升产品精度具有决定性作用。近些年来，国内机床行业在数字化设计方面取得了很大的进步，但在影响机床整机性能的结合面特性，尤其是针对高速类机床结合面特性的建模和参数识别研究方面尚存在不足。因此，本文以直线电机进给系统滑动导轨结合面、HSK主轴刀柄结合面以及动压轴承结合面三种典型的高速类机床结合面作为对象，分别提出对这三种结合面的动态特性建模和参数辨识方法，并在此基础上开发了结合面特性资源库，为机床的数字化设计提供支持。论文主要对高速类机床中三种典型结合面的动态特性参数的辨识方法进行研究。使用弹簧阻尼单元对直线电机进给系统滑动导轨结合面、HSK主轴刀柄结合面进行等效处理，对其动力学模型进行构建并且进行有限元模态仿真分析，并且使用LMS Test.Lab对这三种结合面结构进行模态试验。以LMS Test.Lab模态试验结果为基础，结合有限元仿真分析结果，提出对其结合面动态特性参数的辨识方法，并且对直线电机电磁力与其滑动导轨结合面动态特性的关系以及拉刀力与HSK主轴刀柄结合面动态特性的关系进行研究。基于Fluent对动压轴承结合面进行研究，采用Gambit按照分割划分的策略对动压油膜建立网格模型，构建其有限元模型并且进行仿真分析，对主轴转速与油膜刚度的关系以及进出油口压力差与油膜刚度的关系进行研究及分析。在对三种高速类机床结合面动态特性研究的基础上，以B/S为架构体系，ASP.NET技术为基础，使用HTML、CSS以及Javascript脚本语言，采用Visual Studio 2012为工具开发“数控机床结合面特性资源库”，包含数种典型结合面数据库以及相关结合面建模分析方法的案例，为机床的数字化设计提供支持。

As a key technology to the digital design and development of machine tools, CNC machine tool joint surface analysis and modeling plays a decisive role in accurately predicting product performance and improving product accuracy. In recent years, the domestic machine tool industry has made great progress in digital design, but there are still some shortcomings in the characteristics of the joint surface that affect the performance of the machine tool, especially for the modeling and parameter identification of the joint surface characteristics of high-speed machine tools. Therefore, this paper takes the three typical high-speed machine tool joints and proposes the dynamic characteristics of these three joint surfaces. Modular and parameter identification methods, and based on this, developed a joint feature resource library to support the digital design of the machine tool.The paper mainly studies the identification methods of dynamic characteristic parameters of three typical joint surfaces in high-speed machine tools. The spring damping unit is used to perform equivalent processing on the sliding guide joint surface of the linear motor feed system and the HSK spindle shank joint surface.
