A new automatic program to generate parametric model of shield cutter head

The key parameters for structural characteristics of shield tunnel machine's cutter head were selected based upon some typical structures used in the design of cutter heads. Then a new parametric model generation program of finite elements numerical model in ANSYS' APDL language was developed for the further analysis. The program can automatically generate a parametric finite elements model of shield cutter head to use in the analysis of the strength and stiffness of shield cutter head.
