摘　　要：针对高速高精密机床结构和技术特点,本文对其进给系统及动力学性能结构进行分析。给出了高速高精密机床进给系统结构,采用SolidWorks软件建立机床模型,并在Adams中建立虚拟样机模型,同时,结合有限元软件HyperMech进行网格划分,将生成丝杠的柔性体导入Adams中,建立机床进给系统刚柔耦合模型,并对机床进给系统的刚性体和柔性体进行动态仿真分析。仿真结果表明,刚性体丝杠在垂直方向和水平方向上的变化都非常微小,几乎不发生变化;柔性体丝杠在垂直方向和水平方向上位移变化值均为0.15mm,反复呈周期性变化。该研究为实现高速高精密机床进给系统的准确分析提供了理论依据。According to the structure and technical characteristics of high speed and high precision NC lathe, the feeding system and dynamic performance structure are analyzed in this paper. The structure of high speed and high precision NC lathe feed system is given, using SolidWorks software to establish the model of machine tool, and the establishment of the virtual prototype in Adams at the same time, combined with the finite ele-ment software （HyperMesh） mesh generation will screw flexible body into Adams, a rigid flexible coupling machine into the system model, and the machine tool feeding system rigid body and flexible body dynamic simu-lation analysis. The simulation results show that the changes of the rigid body screw in the vertical direction and the horizontal direction are all very small, almost no change; flexible screw displacement in vertical direc-tion and horizontal direction change values is 0. 15 mm, repeated cyclical changes. The research provides a theoretical basis for the accurate analysis of the feed system of high speed and high-precision NC lathe.
