Theoretical study reveals the inerter as a true spring dual in mechanical networks, suggesting practical applications in vibration absorption and vehicle suspension.

Key Points

To resolve the structural limitations of passive mechanical network synthesis by developing a true mechanical dual element to the spring.
Introduced the mathematical definition and physical concept of the inerter, a two-terminal mechanical element distinct from traditional grounded mass elements.
Applied electrical network synthesis theorems to mechanical one-port systems using positive-real impedance criteria.
Modeled potential applications of the inerter in mechanical simulation, vibration absorption, and vehicle suspension strut designs.
Demonstrated that the inerter establishes a complete analogy between electrical circuits and passive mechanical networks without needing one terminal grounded.
Proved that any arbitrary positive-real impedance can be synthesized mechanically using components that require only small physical mass relative to their host structures.
Showed qualitative performance improvements when applying inerters to passive vehicle suspension struts and vibration suppression setups.
