最近提出了一种新的理想机械单端口网络元件--惯性元件，并证明它是可实现的，它的外力与元件上的相对加速度成正比。本文对几种简单的被动悬架支柱进行了比较研究，每个支柱最多包含一个阻尼器和惯性元件，初步探讨了该元件的潜在性能优势。与传统的被动悬架支柱相比，在四分之一车厢模型中，几种不同措施的性能得到了改善。还进行了一辆全车模型的研究，与传统的被动悬架支柱相比，性能也有所改善。研制了一台样机并进行了试验。实验结果表明，这种特性是传统的仅由弹簧和阻尼器组成的被动压杆所不能达到的。
A new ideal mechanical one-port network element named the inerter was recently introduced, and shown to be realisable, with the property that the applied force is proportional to the relative acceleration across the element. This paper makes a comparative study of several simple passive suspension struts, each containing at most one damper and inerter as a preliminary investigation into the potential performance advantages of the element. Improved performance for several different measures in a quarter-car model is demonstrated here in comparison with a conventional passive suspension strut. A study of a full-car model is also undertaken where performance improvements are also shown in comparison to conventional passive suspension struts. A prototype inerter has been built and tested. Experimental results are presented which demonstrate a characteristic phase advance property which cannot be achieved with conventional passive struts consisting of springs and dampers only.
