| Abstract | Now-a- days shield machine is controlled by the expert system
or artificial intelligence system. There is no mathematical model
at present which can apply for any size and shape of shield machine
to simulate it. This research study is the first time and first
initiative towards the development of that type of simulator.
This research study mainly focus on the analytical formulation
of two dimensional shield machine simulator model and finally
developing a computer program based on that analytical formulation
taking account of relative displacement. Rectangular cross section
of shield with unit thickness (due to two dimensional mode l) was
used for this analysis. The computer program finally calculate the
trace of cutter face , trace of center of jack, rotational
angle(A0), advancement of shield machine(Aq, Ar), radius of
curvature(R) of the trace of cutter fac e at each step. After the
considerable number of steps, the shield machine comes to steady
state condition and it further travel along a circular path. The
radius of curvature shows the behavior of shield machine. Results
obtained from various type of data have been p resented at the end . |
