In the study of mechanical networks in control theory, an inerter is a two-terminal device in which the forces applied at the terminals are equal, opposite, and proportional to relative acceleration between the nodes. Under the name of J- damper the concept has been used in Formula racing car suspension systems. Department of Engineering. Society of Instrument and Control Engineers (SICE).
University of Cambridge. The cloak of secrecy has been lifted from the inerter , but how do J-Dampers really work and what can they be employed to do?
The secret to mechanical grip is to reduce rapid load variations at the tyre contact patch. This simple truth has been known for years and is the objective of tuning suspension . RODOLFO DE VITAyears ago. I have been head of RD on Dual Mass Flywwheel for 8. Using this developed model, the impact of actuation devices such as tuned mass- damper (TMD) and tuned mass-damper- inerter (TMDI) in vibration reduction of this structure is investigated.
Then, the effect of TMDI on the 5DOF model accounting for physical limitations due to system parameters is presented. This paper considers the use of a tuned inerter damper (TID) system for suppressing unwanted cable vibrations.
