在分析悬臂式掘进机掘进断面成形控制原理的基础上,建立了基于角位移和检测液压缸行程的断面几何参数的匹配模型,得出了掘进机巷道断面成形尺寸与传感器检测量及断面成形控制精度与传感器精度之间的数学关系,为断面成形控制中传感器的精度选择及截割轨迹监控系统的可视化数据采集提供了理论基础。 Based on the analysis of the control principle of cantilever boring machine heading section forming, the matching model of section geometry parameters based on angular displacement and hydraulic cylinder stroke is established, and the forming dimensions of tunnel boring machine section, sensor detection and section forming control The mathematical relationship between the accuracy and the accuracy of the sensor provides a theoretical basis for the selection of the accuracy of the sensor in the cross-section forming control and the visual data acquisition of the cutting trajectory monitoring system.
