Usually a gear engagement generates more vibrations in the system and it is a main reason behind the noise under the heavy load and speed. To suppress these vibration the particle damping technology is considered in this paper. The particle damper is inserted in the inherent holes on the periphery of gear, it is nothing but the one type of passive method to reduce the vibrations. The particle damping is all about adding some auxiliary mass to the system. By means of this the inelastic collisions occur in the gear transmission in order to dissipate the energy into gear transmission. With the usage of dynamic analysis, various boundary condition of centrifugal field of the gear transmission are obtained in this paper. Subsequently discrete element method is employed to examine the dynamics and kinematics of those particles and also the relation between the surface roughness (i.e. coefficient of friction) and energy dissipation at various load and speed are arrived at. Later through simulation it is observed that smoother particle offers better damping effect at low rotational speed, while rougher particle shows good damping effect with high speed. Finally all the simulating results are compared with experiments so as to offer theoretical framework to the practical observations.
