Modeling roll contact curves

Abstract

Roller devices equipped with deformable coatings are crucial for various mechanical operations in material processing. Understanding the contact lines between these rollers and deformable coatings is essential for revealing physical phenomena in roller devices. This study derives analytical expressions for contact curves based on the physical phenomena in the deformation zone. It has been established that the factor that most influences the mathematical model of the contact curve of the rolls is the ratio of the deformation rates of the roll coating to the deformation rate of the processed material during compression.
