Paper Abstract

The simplest model for vibration isolation design is the single-degree-of-freedom (SDOF) mass-spring-damper system. This system has been widely analyzed, however, it has been argued that the SDOF model is not a good design model and a two-degree-of-freedom (2DOF) model should be used instead. This paper delves into the limitations of the SDOF model and the advantages of the 2DOF model to design vibration isolation systems. The reduction in system transmissibility by using active damping versus passive damping is also discussed for both models.
