The vibration generates difficulties to the structure which reduces the structure life and increases the possibilities of failure to the structural. This paper presents a review on research carried out on behaviour of various parameters of particle impact damping. The methods like experimentation, analytical and discrete element method to validate results were used. Actual modelling of the experiment is done and using vibration exciter vibrations are given and readings are recorded by FFT analyser. Researchers have used the parameters like packing ratio, material of beam, material of fine particles and its size. Some researchers have focussed on the design methodology of the particle damping. While experimentation beam is studied with particles and without particles. The particles were used like copper, aluminium, glass, sand, lead, tungsten carbides. The material of the beam is used as aluminium and steel so that the experimentation is carried out on the beam. It is found that the particle impact damping is most effective for vibration suppression. The damping performance of particle impact damper has been found highly nonlinear behaviour. This paper focuses or discusses on the methods to reduce vibrations by using particle impact dampers.
