【Abstract】 The finite element model of TBM cutterhead is established. In order to verify the effectiveness of the modeling method for the static and dynamic characteristics of the model, set up the scale model of TBM cutterhead. Analyze the dynamic characteristics of the scale model and accuracy of the model whether verified by experiment. The loading form of cutterhead load in finite element analysis is described. Conduct the static and dynamic characteristics analysis of TBM cutterhead.更多还原
