Modelling the hysteretic behaviour of a fluid inerter for use as a parallel-viscous-inerter-damper device
The use of inerter-based devices has been investigated for a range of engineering applications.In structural engineering,inerters have been proposed for use in buildings,bridges,and other structures.In this paper,we discuss the practicalities of using a fluid inerter device in this type of scenario,and show that helical designs of fluid inerter are well suited for use as parallel-viscous-inerter-damper devices(PVID).This type of PVID can be achieved using a fluid inerter combined with a linear spring connected in series.The fluid inerter creates both inertance and damping forces in one device and these properties can be designed based on the geometry of the device.Based on experimental observation of a fluid inerter system,results show that the inerter has significant hysteresis.Tests also showed that the area inside the hysteretic loop is strongly effected by frequency and amplitude of the excitation.Thus,we propose a new hysteretic model for a fluid inerter that is based on a linear damper and inerter element combined.
