Recently in the shield machine cutter rock breaking simulation, the stress on body feels wrong, ask the shield machine general disc stress on the hob is, what about the magnitude is hundreds of MPa or greater?
30MPa, the answer is complete.
Different strata use different types of hobs, and the rock breaking ability is the most natural rock shield machine
The relationship between the cutter torque, the hob torque and the installation radius of the shield machine between the three
