The performance benefits of passive vibration suppression with network configurations consisting of stiffness, damping and inertance elements have been demonstrated for a wide range of mechanical systems. Considering physical implementations of these beneficial network configurations, hydraulic realisations have the advantages of durability and simplicity for integration with existing hydraulic dampers. Such designs are exemplified by fluid inerters and fluid-inerter-damper devices. However, in contrast to the convenience of realising inertance and damping elements, realising ‘embedded’ stiffness is very challenging. We use ‘embedded’ to refer to a network element, which is not purely in series or in parallel with the remainder of the network but instead lies within the network layout. In this work, a setup using a rubber membrane to realise such embedded stiffness is proposed, together with a procedure for hydraulic implementations of any stiffness-damping-inertance configurations. The nonlinear properties of the embedded stiffness due to rubber membrane properties are then investigated both theoretically and experimentally. In addition, the effectiveness of both the membrane setup and the design procedure are demonstrated via a case study of suspension design for passenger vehicle ride comfort enhancement.

由刚度、阻尼和惯性元件组成的网络配置的被动振动抑制的性能优势已在广泛的机械系统中得到证明。考虑到这些有益网络配置的物理实现，液压实现具有与现有液压阻尼器集成的耐用性和简单性的优点。这样的设计以流体惰化器和流体-惰化器-阻尼器装置为例。然而，与实现惯性和阻尼元件的便利性相比，实现“嵌入式”刚度非常具有挑战性。我们使用“嵌入式”来指代网络元素，它不是纯粹与网络的其余部分串联或并联，而是位于网络布局内。在这项工作中，提出了一种使用橡胶膜来实现这种嵌入刚度的设置，以及任何刚度-阻尼-惯性配置的液压实施程序。然后通过理论和实验研究由橡胶膜特性引起的嵌入刚度的非线性特性。此外，膜设置和设计程序的有效性通过用于提升乘用车乘坐舒适性的悬架设计案例研究得到证明。
