### Model of Grinding Force Based on Stress Concentration Theory

Stress concentration theory was introduced into study of grinding and the stress concentration phenomenon in grinding process was analyzed.A single-grit model of grinding force was established based on stress concentration theory.The influence mechanism of grit-wear-area rate on cutting force was clarified with the model.Functions between grinding force and grit-wear-area rate was established

Chat More### The blending of theory and practice in modern rail grinding

Modern rail grinding practices have developed largely through a combination of field experience and intuitive speculation. Many theories related to crack initiation and growth have been proposed through the decades and those concepts have been cleverly extended to the field of rail grinding to form the basis of the practice known as preventive grinding .

In grinding process a small amount of grinding fluid can be injected into the contact area for cooling and lubrication. This leads to decrease of the grinding fluid utilisation efficiency and workpiece surface integrity. Based on fluid mechanics theory a mathematical model of two-phase flow field is established and the simulation of the grinding fluid jet is carried out by FLUENT.
