典型TBM刀盘力学性能分析与对比
Mechanical performance analysis and comparison of typical TBM cutterhead
摘要
Abstract
To compare the mechanical performances of different typical full⁃face rock tunnel boring machine ( TBM) cutterheads, in this study, we revised the overturning moment calculation model. We then calculated the distribu⁃tion of the overturning moment under three different working conditions, i. e., ideal conditions, a soft⁃upper and hard⁃under stratum, and conditions in which part of the cutters are worn. Using finite element simulation, we also studied the cutterhead stress distribution in the process of excavation. The results show that the cutterhead’ s radial load is far less than its overturning moment, and therefore the overturning moment has a much greater effect on the cutterhead’ s performance. The overturning moment caused by a positive cutter loading is the largest, followed by edge⁃cutter loading, and the minimum loading is caused by a center cutter. In a worn cutter condition, the maxi⁃mum total overturning moment of cutterhead A is greater than 2 800 kN·m, which is 7% greater than the ideal. The overturning moment of the star topology cutterhead is smaller than that of the spiral cutterhead, and its mechan⁃ical performance and strength property is superior.关键词
