摘要

为明确WC陶瓷颗粒单胞结构对盾构机滚刀刀圈蜂窝结构增强体的抗压性能的影响,利用绘图软件对体积分数为36％WC颗粒(四边形、六边形、八边形)的滚刀刀圈蜂窝结构增强体进行三维空间结构设计,通过ANSYS有限元模拟仿真分析不同单胞结构增强体的抗压性能.结果表明:WC颗粒体积分数为36％,四边形单胞结构增强体的极限压缩强度为123MPa、六边形的极限压缩强度为125 MPa、八边形的极限压缩强度为121 MPa,体积分数为36％的正六边形蜂窝结构增强体的抗压性能最优.

Abstract

In order to clarify the influence of WC ceramic particles'single-cell structure on the compres-sive performance of the honeycomb structural reinforcement of the hobbing cutter ring of shield machine,the three-dimensional spatial structure of the honeycomb structural reinforcement of the hobbing cutter ring with 36％WC particles in volume fraction(tetragonal,hexagonal,and octagonal)is designed using the drawing software,and the compressive performance of the reinforcement with different single-cell structure is analyzed by ANSYS finite element simulation.The results show that the ultimate compressive strength of the WC particles with volume fraction of 36％is 123 MPa for quadrilateral,125 MPa for hexagonal,and 121 MPa for octagonal,and the compressive performance of the ortho-hexagonal cellular reinforcement with volume fraction of 36％is optimal.
