Numerical Simulation Analysis in Cooling Temperature Field and Bending Deformation after Rolling of 100-Meter Rail
The paper established U75V 100-meter rail 3-D transient non-liner finite element analysis model about U75V 100-meter rail by using the large-scale non-liner finite element analysis software ABAQUS. By analyzing the different positions in the section of the temperature variation, the changes of bending degree and the residual stress variation after the bending deformation have changed. Based on the 100-meter straight rail in natural cooling under the cooling process, simulation results showed that in the cooling process, deflection change with time mainly divided into four stages; In consideration of the friction effect, the flat rail cold curve for its deformation among roughly flat, the curve about either ends, the scope for bending is 18 meters, the maximal displacement is 1.88 meters while the flat rail occured end colding.
