2010-3-18 · Prediction of the Stress Distribution and Roll Force for the Roller Compaction. Modeling the stress distribution of a granular material in a roller compactor has interested researchers since the 1960s. The stress distribution gives a handle on the roll force and torque and hence benefits the design and simulation of the process.
If you want to calculate the force you will need to multiply the kgf/cm2 value (which is a pressure) by the cross sectional area of the hydraulic ram/cylinder in square centimeters. If the force is 1 kgf and the area 1 cm2, then the pressure in bar would equal 1.0197162 bar. F (kgf) = P (bar) x A (cm²) x 1.0197162.
