纠偏前筒与后筒的几何关系对纠偏性能的影响

The Influence of the Geometrical Relationship between Steering Head and Machine Can on the Steering Capability

本文着重分析了机械顶管纠偏结构在机头的几何分布位置，分析了纠偏前筒与后筒的几何比例对纠偏系统灵敏性、稳定性、有效性的影响。并根据实测数据，从这三个方面分析评价了当前三种泥水平衡式顶管机纠偏系统的性能。

Geometrically positioning of steering cylinder on the tunnelling machine was discussed in this paper to analyze its effect on the sensitivity, stability and validity of the steering system. Afterwards, fieldwork measured data were involved to evaluate the capabilities of three currently-used steering systems of tunnelling machine of slurry balance on these three aspects.
