Description

technical field [0001] The invention relates to the field of numerical control machine tool processing, in particular to a flexible body dynamics analysis method of a large hard rail machining center. Background technique [0002] Large hard rail machining center is one of the very important CNC equipment, mainly used for processing large parts, suitable for heavy cutting and high processing efficiency. Since many factors such as machine tool assembly, workpiece gravity, cutting force, and inertial force during acceleration and deceleration will affect the dynamic stiffness of the machine tool, it is necessary to perform a dynamic analysis of the machine tool to analyze the deformation and reaction of the basic components during its movement. In order to improve the machining accuracy and efficiency of the machining center and reduce the manufacturing cost, it provides guidance on the optimization of the machine tool structure. Existing technologies cannot meet the needs of...
