Effect of ceramic particle cell structure on compressive performance of composite cutter ring reinforcement for shield tunneling machine
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.
