The development of control and isolation strategies for shock induced vibration has experienced a recent interest due to the increasing demand in improved isolation requirements for sensitive equipment subjected to harsh environments. Shock vibration is a common problem that is present in many situations, such as ground motions, blast, explosions, crash, impact, etc. This paper reviews the fundamentals of shock isolation theory, and presents a literature survey of the most important works developed in the field, focusing on non linear shock isolation systems exploring theoretical and experimental results, focusing on recent advances. A model for a shock isolation system based on nonlinear stiffness is proposed, showing theoretically and experimentally its feasibility in the reduction of maximum transmitted acceleration in impact subjected systems.
