The aim of this paper is to study a novel fluid-coupling vibration isolator to improve the dynamics in a harsh vibration-impact environment for packaging reinforcement systems of electronic equipment. The fluid-coupling isolator is designed through coupling the air, oil, rubber, and spring. The dynamic characteristics of the actual fluid-coupling isolator are developed. The test results of the prototype in dynamic tests show complex nonlinear dynamic characteristics. Based on this, a nonlinear dynamic model for the fluid-coupling isolator is presented. Comparisons with experimental data confirm the validity of the model. It builds a basis for future work in engineering design and evaluation of packaging protection system for electronic equipment.
