This paper investigates the use of a two-terminal vibration suppression device in building. The inerter-spring-damper configurations for multi-storey building structure is considered. inerter has been used Formula 1 racing cars and applications to various systems such as road vehicles have identified. Several devices that incorporate inerter(s), well spring(s) damper(s), also identified structures. These include tuned damper viscous mass damper. In this paper, three-storey model with...
Linear passive vibration absorbers, such as tuned mass dampers, often contain springs, dampers and masses, although recently there has been a growing trend to employ or supplement the elements with inerters. When considering possible configurations these broadly, two approaches are normally used: one structure-based immittance-based. Both have their advantages disadvantages. In this paper, new approach is proposed: structure–immittance approach. Using approach, full set of series–parallel...
For modern electrical rail systems, the pantograph-catenary dynamic performance is one of most critical challenges. Too much fluctuation in contact forces leads to either accelerated wear contacting components or losses and, consequently, arcing. In this work, inertance-integrated pantograph damping systems are investigated with objective reducing force standard deviation. Firstly, a multibody model developed its accuracy compared experimental data. The improved through calibration head...
Summary This paper provides a complete realisation of special class positive‐real bicubic impedances. The problem is motivated by the concept inerter, which mechanical dual capacitor. device allows network synthesis, completing electrical analogy. With emphasis to minimise number elements required allow feasible implementation. definitions simple‐series‐parallel networks and essential‐regular functions are introduced. minimum‐reactive that can realise all bicubics identified grouped into six...
This paper investigates the use of two two-terminal vibration suppression devices in a building and assesses performance benefits over those achieved using single device. The inerter-combined configurations for multi-storey structure are considered. inerter is device, with property that applied force proportional to relative acceleration across its terminals. In this paper, five-storey model absorbers same kind subjected base excitation studied, where one located between ground first floor...
This paper investigates the use of inerters for vibration suppression a multistorey building structure. The inerter was proposed as two-terminal replacement mass element, with property that applied force is proportional to relative acceleration across its terminals. It completes force-current mechanical-electrical network analogy, providing mechanical equivalent capacitor. Thus allows all passive impedances be synthesised. has been used in Formula 1 racing cars and applications various...
Reichert's theorem (1969), a fundamental of network synthesis, completely characterises minimum reactive synthesis positive-real biquadratic impedances. The crucial part the original approach depends on complicated topological argument. This paper provides an alternative proof using recently introduced concept regular functions.
This paper presents the numerical study on propagative waves in a periodically supported rail below 6000 Hz. A periodic model, which considers effects of both supports and cross section deformation, has been established based structure theory finite element method. Two selection approaches are proposed to obtain concerned dispersion curves from original calculation results relations. The differences between different support conditions studied. corresponding identified by wave modes....
This paper proposes a new method, the structure-immittance approach, for designing passive vibration absorbers consisting of inerters, dampers and springs. When considering possible configurations these elements broadly, one two exist approaches may be taken, either structure-based or an immittance-based approach. Both methods have their advantages disadvantages. In this paper, approach combines existing ones. It can both consider full set absorber layouts together (the advantage approach),...
Tuned mass dampers (TMDs), in which a reaction is attached to structural system via spring–parallel–damper connection, are commonly used wide range of applications suppress deleterious vibrations. Recently, mass-included absorber layout with an inerter element, termed the tuned damper (TMDI), was introduced, showing significant performance benefits on vibration suppression. However, there countless layouts springs, and inerters, could potentially provide more preferred dynamic properties....
The performance benefits of passive vibration suppression with network configurations consisting stiffness, damping and inertance elements have been demonstrated for a wide range mechanical systems. Considering physical implementations these beneficial configurations, hydraulic realisations the advantages durability simplicity integration existing dampers. Such designs are exemplified by fluid inerters fluid-inerter-damper devices. However, in contrast to convenience realising elements,...
