Gear transmission system is widely used for many mechanical applications to transfer power. Specially in case of spur gears, due to high speed and heavy loading conditions the vibrations are unavoidable. This result in reduction in service life of gear. Particle damping is one of the passive vibration damping technology. This dissertation work deals with use of particle damping technique to reduce the vibration in gear system by dissipating vibrational energy in particle collisions. Theoretical analysis of particle damping is carried out to determine the important parameters which affect its performance. Single stage spur gear system is used for project work. Static structural and modal analysis is performed using FEA tool to find stress distribution and natural frequencies at various modes. Using Taguchi method of design of experiment, total nine test runs are identified for two parameters at two different level. Suitable DEM tool is used to perform simulations at different speed and to analyse the energy dissipation during particle collisions. The effect of particle size and particle filling percentage is analysed for gear having six holes to fill particles. The results can be used as guide for applying particle damping under centrifugal load.
