Design Optimization About the Car of Deep-roll Bending and Pressure Roller Volume Based on the Finite Element Method

Being beyond the design or requirements has been some problems with working about the car of deep-roll bending and pressure roller volume,the paper research the whole body of the car and stress and strain to use the finite element method.Some problems have been taken about the car's structure to make some optimal design.To the design or requirements,the paper has made a reasonable Solution.
