A Comparison of a Semi-Active Inerter and a Semi-Active Suspension
SAE Technical Paper Series, 2010<div class="section abstract"><div class="htmlview paragraph">Inerters have become a hot topic in recent years, especially in vehicle, train, and building suspension systems. The performance of a passive inerter and a semi-active inerter was analyzed and compared with each other and it showed that the semi-active inerter has much better ...

The Journal of the Acoustical Society of America, 2007
A shock and vibration isolator that includes a double acting mechanical spring assembly that is mounted to act in parallel with a fluid or liquid spring assembly. The mechanical spring is arranged to provide a first spring rate over a first displacement range and a second spring rate over a further second displacement range.

Semi-Active Multiple Beam Arrays
2019 URSI International Symposium on Electromagnetic Theory (EMTS), 2019The low power efficiency (5-15%) of solid state power amplifiers, working in back-off to guarantee a good linearity, could become the show stopper for some future space and terrestrial communication ventures at Ka-band and above. Semi-active reflector and conformal antennas, using Butler-like matrices between the power amplifiers and the feed elements,

Design of a semi-active knee prosthesis
2009 IEEE International Conference on Robotics and Automation, 2009Current state-of-the-art prostheses for transfemoral amputees operate exclusively through controlled damping or through fully powered gait imitation. The passive devices cannot restore a natural gait, and the active devices are large and inefficient. This paper summarizes the design of a new semi-active prosthetic knee that combines the proven safety ...

A semi-active ABW AWA suspension (Fig. 5.30) mechatronic control system is much less complex than an active ABW AWA suspension mechatronic control system, and may be manufactured at a lower cost [DAS 2006].

Application of Semi-Active Inerter in Semi-Active Suspensions Via Force Tracking
Journal of Vibration and Acoustics, 2016This paper investigates the application of semi-active inerter in semi-active suspension. A semi-active inerter is defined as an inerter whose inertance can be adjusted within a finite bandwidth by online control actions. A force-tracking approach to designing semi-active suspension with a semi-active inerter and a semi-active damper is proposed in ...
