Study on Vibration and Damping of Printed Circuit Boards Treated with Partial Constrained Damping Layer

Abstract

Constrained damping layer (CDL) treatment has been an effective way to suppress vibration level of various structures. by introducing this method into the vibration control system of electronic equipments, this paper firstly discussed the dominant mechanism difference between free damping layer treatment and constrained damping layer treatment, Then base on the constrained layer damping layout optimization method in the vibration system of a rectangle thin board like PCB, a series of experimental investigations were presented on the vibration response of printed circuit boards treated with partial constrained damping layers. as a result, it proves the CDL treatment having good effect on vibration response control of PCBs.

“…The vibration amplitude can be reduced by the kinetic energy generated by the collision of particles and friction between the particles in the container. To date, several studies have been performed to investigate various types of PIDs [13,15,16].…”

“…Амплітуду вібрації можна зменшити за рахунок кінетичної енергії, що генерується зіткненням частинок і тертям між частинками в контейнері. На сьогоднішній день було проведено кілька досліджень для дослідження різних типів PID [13,15,16].…”
