Two types of passive devices, namely, negative stiffness damper (NSD) and inerter damper (ID), have been receiving growing interest in vibration isolation and suppression, because both can produce negative-slope force-displacement relationships that are similar to those associated with active control forces. Despite such a similarity, these two passive dampers possess obvious differences in their mechanical behaviors. This study aims to illustrate the similarity and difference between these two dampers in vibration isolation applications with respect to the H-2 and H-infinity performance. The comparative study indicates that both dampers can reduce the H-infinity norm effectively; the negative stiffness devices can reduce the H-2 norm as well, whereas the H-2 norm cannot converge under the influence of inerter. This finding explains why a tuned-inerter damper, i.e., an inerter connected in series with a spring with proper frequency tuning, is more commonly adopted in vibration isolation. The pros and cons of both devices were further discussed. (C) 2019 The Franklin Institute. Published by Elsevier Ltd. All rights reserved.
