Quick response particle damper for printed circuit boards and planar surfaces

Abstract

An apparatus and system for attaining quick response to vibration damping of a printed circuit board (PCB) or other planar surface utilizing a defined travel displacement of a single spherical tungsten (or other material) ball in a single or plurality of sealed spherical chambers in a particle impact damper (PID). The single spherical tungsten (or other material) ball is not weighed down, constrained, encumbered or influenced by other spherical balls within the chamber; accordingly, providing unrestricted freedom for the ball to quickly respond at the first occurrence of excessive vibrational acceleration over 1G. The structure of a single spherical particle within a sealed spherical chamber also provides a path of minimum distance for the ball to travel before colliding with the ceiling or side walls of the PID chamber. A plurality of spherical chambers can be arranged in a variety of patterns within the PID housing such as desired. The PID housing can be any shape such as a cube, a rectangular cuboid, a cylinder, sphere, triangular tetrahedron, triangular prism, polygon, toroid or any combination of shapes.
