To study the friction and wear of the brake disc and pad,mathematical equations were used to calculate the wear depth.Because the change element of materials in finite element software is difficult to achieve,there is a certain limitation on the calculation of wear depth and the expression of wear profile by the software of ANSYS and ABAQUS.STUDY BEHAVIOR THE COEFFICIENT OF FRICTIONSTUDY BEHAVIOR THE COEFFICIENT OF FRICTION AND WEAR RATE OF coefficient of friction,wear rate.1.INTRODUCTION Friction is the resistance to movement of one body over other body.The word comes from the Latin verb fricare If material is forged at high temperature,it tends to crack and disintegrate.The material is often called HOT Related searches for Study on High Temperature Friction ajournal of friction and wearfriction and wear of materialsPrevious123456Next
