This work studies the influence of a vibration isolator on the response of a flexible base structure. Two strategies are compared: passive and active vibration isolation (PVI, AVI). Although the multiple advantages of AVI over PVI techniques are well known, their effect in the base structure has not to date been compared. This interaction has an important role in the performance of the general control system, especially when the vibration isolation system is not the only system on the base structure or when there are multiple isolators working simultaneously on it. In addition, the structural serviceability of the base structure can also be affected. The analysis of the vibration isolation problem is made from a wide perspective, including the effect that isolator has on the base structure. Hence assuming the base structure is a non-rigid system. The effect of the isolation system on the base response is studied for an extensive range of base structures, thus showing different possible scenarios. The influence is quantified by comparing the peak magnitude response of the base when both passive and active vibration isolation techniques are used. The theoretical results have been corroborated by undertaking experimental tests on a full-scale laboratory structure.

这项工作研究了隔振器对柔性基础结构的响应的影响。比较了两种策略：被动和主动隔振（PVI，AVI）。尽管AVI优于PVI技术的多重优势是众所周知的，但迄今为止，它们在基本结构中的作用尚未进行比较。这种相互作用在通用控制系统的性能中起着重要作用，尤其是当隔振系统不是基础结构上的唯一系统或有多个隔离器同时在其上工作时。此外，基础结构的结构可使用性也会受到影响。从广泛的角度分析了隔振问题，包括隔振器对基础结构的影响。因此，假设基本结构是非刚性系统。对于广泛的基础结构，研究了隔离系统对基础响应的影响，从而显示了不同的可能情况。当同时使用被动和主动隔振技术时，可通过比较基座的峰值幅度响应来量化影响。通过在完整规模的实验室结构上进行实验测试，证实了理论结果。
