Six degree of freedom active vibration isolation using quasi-zero stiffness magnetic levitation.
Vibration is recognised as one of the most significant disturbances to the operation of mechanical systems. Many traditional vibration isolator designs suffer from the trade-off between load capacity and isolation performance. Furthermore, in providing sufficient stiffness in the vertical direction …

Development of a Novel Controllable Seismic Isolation System Based on Negative Stiffness Concept
… stiffness devices (ASNSDs) and other base isolators to contribute new knowledge to the seismic protection field. Firstly, the beneficial effects of nonlinear damping and stiffness on seismic protection are investigated in the form of proposing a modified ASNSD with open-loop control. It has …

Design of compliant mechanisms for attenuation of unidirectional vibrations in rotational systems
… (1) attenuate undesired small-motion angular vibrations in rotational power transmission systems and (2) preserve the desired transmission of large-motion torque/angle inputs. This thesis investigates the design of vibration attenuating compliant mechanisms that are directly integrated into …

Two Dimensional Analysis of Vibration Isolation of Rigid Bar Supported by Buckled or Pre-bent Struts
… of this research is to study a new type of vibration isolator, utilizing the post-buckled stiffness of elastic struts (or columns). The advantage of the post-buckled state is that ideally it can support more static load with a relatively small static deflection than traditional vibration …

Vibration Isolation of a Horizontal Rigid Plate Supported by Pre-bent Struts
… of this research is to analyze a new type of vibration isolator consisting of two pre-bent struts which are clamped at both ends and intermediately bonded with a viscoelastic filler. The proposed isolation device has the ability to support a relatively large static load with little deflection …

The Effect of Composition on the Linear and Nonlinear Mechanical Properties of Particulate Filled Elastomers
… upon load removal. From car tires to building vibration isolator systems, elastomers are the most versatile of engineering materials. The inclusion of particulate fillers into elastomers enhances their mechanical properties (modulus, tensile strength, toughness, tear resistance, etc) thereby …

Mechanical Energy Harvesting for Powering Distributed Sensors and Recharging Storage Systems
Vibration energy harvesting has been widely investigated by academia and industry in the past decade with focus on developing distributed power sources. One of the prime goals of energy harvesters is to provide power to wireless sensors allowing for the placement of these sensors in the remote and …

Analysis of Buckled and Pre-bent Columns Used as Vibration Isolators
Vibrations resulting from earthquakes, machinery, or unanticipated shocks may be very damaging and costly to structures. To avoid such damage, designers need a structural system that can dissipate the energy caused by these vibrations. Using elastically buckled struts may be a viable means to …
