摘　　要：为提高纵轴式掘进机在巷道内的行驶性能,以天河科技EBZ200M-4型掘进机为研究对象,分析履带板与底板之间的力学性能,并结合EDEM、RecurDyn和Ansys软件对其行驶性能与履带力学特性进行仿真分析。结果表明:由于两侧履带张紧力不同,掘进机在3 mm颗粒模型行驶向左侧偏移,在5和7 mm颗粒模型行驶向右偏移,但行驶偏移量范围均在5~6 mm之间,相差不大。掘进机在7 mm颗粒模型的下沉量最小,为16 mm。C型履带板沉陷量为14.6 mm,侧向载荷标准差为138.3 N,相比于传统A型履带板抗侧滑能力提升了22.1%,应力最大值为79.9 MPa,平均值为2.8 MPa,变形最大值为0.027 mm,平均值为0.006 5 mm。由此可知,掘进机在颗粒尺寸为7 mm模型下的行驶性能最佳,且将传统A型履带板更改为C型履带板后可进一步提高掘进机的行驶性能,为其性能优化提供一定参考。In order to improve the driving performance of longitudinal shaft TBM in roadway,the EBZ200M-4 TBM of Tianhe Technology was taken as the research object to analyze the mechanical properties between track plate and bottom plate,and combined with EDEM,RecurDyn and Ansys software to conduct simulation analysis of its driving performance and track mechanical characteristics.The results show that due to the different tensioning forces of the track on both sides,the TBMS offset to the left in the 3 mm particle model and to the right in the 5 and 7 mm particle model,but the range of offset is between 5 and 6 mm,with little difference.The tunneling machine has the smallest subsidence of 16 mm in the 7 mm particle model.The subsidence of C-type track plate is 14.6 mm,and the standard deviation of lateral load is 138.3 N.Compared with the traditional A-type track plate,the sideslip resistance of C-type track plate is increased by 22.1%.The maximum stress is 79.9 MPa,the average value is 2.8 MPa,and the maximum deformation is 0.027 mm and the average value is 0.0065 mm.It can be seen that the driving performance of the TBM is the best when the particle size is 7 mm,and the driving performance of the TBM can be further improved after changing the traditional A-type track plate to C-type track plate,which provides A certain reference for its performance optimization.
