Abstract
Double-edged hob is commonly used as a tunneling tool when the shield machine works and it is easy to failure due to its insufficient strength in the rock breaking process. In order to solve this problem, the paper used the theory of finite element to do static simulation analysis of the hob. Firstly, the paper generated a three-dimensional model by using the software Pro/E based on a constant cross section double-edged cutter. Then, the maximum stress, maximum strain and their distributions on the double-edged hob could be obtained from static analysis based on the finite element analysis software ABAQUS. Finally, we could get the conclusion that double-edged hob met strength requirements in the test load conditions by comparing the maximum stress and yield strength of hob material. The results of static simulation analysis provided reference to material selection and optimization design of the double-edged hob and cutter head.
