One of the effective methods of passive vibration suppression is through the application of particle damping technique. This paper discusses the novel application of particle damper capsule to suppress the vibration of a Printed Circuit Board (PCB) and study the relationships between the vibration responses and the input force amplitude for various particle damper parameters such as Particle Size (PS), Particle Density (PD) and Packing Ratio (PR). Several experiments were carried out with different combinations of particle damper parameters for the estimation of vibration responses in the PCB for the primary modes of vibration. Based on these, the factors which affect the vibration responses are studied in detail for the chosen combination of system parameters. Also, the relationships between the response and the applied force for various PS, PR, PD and response locations are obtained and they are used to arrive at the design guidelines for the particle damper suitable for spacecraft electronic packages. The vibration suppression of PCB under random vibration environment is performed to demonstrate the effectiveness of the designed particle damper.
