The Simulated Calculation and Optimizing Experimental Research of the Residual Stress of the Heavy Rail Straightening

Abstract:

The finite element 3D model of heavy rail roller complex straightening is established by the finite element method in this paper.The straightening process is optimized by orthogonal experimentation and regression analysis. The formative mechanics and the regulation of the residual stress in the process of straightening are researched. The results of the simulation show that: whatever is on the basement of the residual stress or flatness, the new schedule is better than the real field one, residual stress is controlled within 250Mpa.
