CRTS域型无砟轨道板专用数控磨床定位分析

摘要

By theoretical analysis, the reasonable locations of the anchor points and the magnitude of force in the hydraulic cylinders are determined in the special CNC grinding machine for grinding the CRTSIIrail board.It enables the board to be grinded in a state under the condition of uniform bending moment and the smallest normal stress, so that it reduces the influence of its own internal stress and improves the grinding quality.%通过对CRTSⅡ型无砟轨道板专用数控磨床定位点及支撑力的理论分析，确定了CRTSⅡ型无砟轨道板在专用数控磨床磨削中定位点的合理位置，以及各支撑液压缸支撑力的大小分配比，使CRTSⅡ型无砟轨道板能够在所受弯矩均匀、正应力最小的状态下进行磨削，从而减小了自身内部应力的影响，提高了CRTSⅡ型无砟轨道板的磨削质量。
