Vibration damping is reactive vibration control method, which is mostly used to control and diminish surplus vibrations induced in mechanical systems. In present study, analysis of vibrations for gear box by using particle damping method. In particle damping (PD), an impact mass is tightly attached to the main vibrating configuration to satisfy the vibrations. The impact mass contains number of particles. The dissipation of vibrational energy will occur due to impact, exchange of energy and friction in between main mass and impact mass. Particle impact dampers are used to decrease the undesirable vibration in engineering applications such as gear box. Aim of this study is to perform parametric analysis (Frequency domain and time domain parameters) for vibration of gearbox. The scope of the study is limited to with consideration of particle damping only. This paper attempts to investigate this problem by applying several signal processing and features selection techniques to find the most sensitive features (and sensors) for vibration analysis of the gearbox system under consideration. The methodology followed in this work consists of use of an experimental setup where it is possible to introduce the multiple faults in gear and bearing simultaneously. In Procedure the particle damping method is applied to vibration of gear box in different combinations like 10%,30%50%,70% and 100%. Analysis of this study show that out of 24 parameters only 5-6 parameters show drastically variation. The contribution of this study is a new method is developed wherein vibration using parametric analysis an effect of parametric analysis on particle damping method applied for single stage gearbox to suppress the vibration to improving Impact damping method has been established. This implementation of results of the study are for improving life of the system component.
