An Inertial Measurement Unit Application for a GPR Tracking and Positioning

by Transient Technologies LLC  (Feb. 3, 2014)

Abstract Abilities of an inertial measurement unit (IMU) for ground penetrating radar (GPR) tracking and positioning are presented at this paper. The IMU operation principle is based on calculating of the device's orientation in space via measurement of linear accelerations and angular velocities. Features of the IMU, GPS and wheel odometer are ...

Energy harvesting from suspension systems using regenerative force actuators

by Inderscience Publishers  (Aug. 12, 2013)

In this paper, harvesting vibration energy from suspension is investigated. Theoretical values for the harvested energy are calculated. Experimental evaluation of the energy is performed using vehicle road simulation facilities. An excitation signal in the frequency range of 0.5 Hz to 20 Hz is applied to the vehicle and the harvested power is ...

Construction and Civil Infrastructures Monitoring Systems

by Advantic Sistemas y Servicios S.L  (Aug. 1, 2013)

Civil infrastructures are usually monitored through its whole life cycle. SHM (Structural Health Monitoring) technologies enable the estimation of the structural state and detection of structural change that affects the performance of a structure. Two discriminating factors in SHM are the time-scale of the change (how quickly the state changes) ...

Response of piping system with semi–active variable friction dampers under tri–directional seismic excitation

by Inderscience Publishers  (Jul. 23, 2013)

Seismic loads on piping system due to earthquakes can cause excessive vibrations, which can lead to serious instability resulting in damage or complete failure. In this paper, semi–active variable friction dampers (SAVFDs) have been studied to mitigate seismic response and vibration control of piping system used in the process industries, fossil ...

Minor construction measures that influences vibration in concrete floors from foot steps and electric motors

by Inderscience Publishers  (Jul. 23, 2013)

Concrete floor constructions often suffer from high frequency vibrations. Humans aerobics workouts and various motors are sensitive to that kind of vibrations and it is of interest to find simple methods that reduce floor vibrations and thereby increase the comfort for habitants. Two steel framed concrete floors equipped with a vibration damping ...

Identification of quality attributes of automotive idle sounds and whole–body vibrations

by Inderscience Publishers  (May 22, 2013)

The aims of this study are the generation and comparison of the semantic spaces of vehicle idling sounds and vibrations and the determination of their quality dimensions. In this study, two different sets of quality attributes were developed for idling sounds (34 attributes) and whole–body vibrations (22 attributes). In contrast to prior ...

D.I.Y. Studio Construction

by ALPHA ACOUSTIKI Ltd.  (May 17, 2013)

CHAPTER 1. Introduction Being an engineering company specialized in noise and vibration control we often come across applications in music studios. Noise transmission in studios can be airborne (transmitted via the air) but also structure borne (transmitted via the building elements). Due to the large wave lengths occurring from low frequency ...

Ishibashi tests wind gearboxes with PULSE

by Brüel & Kjær Sound & Vibration Measurement A/S  (Feb. 5, 2013)

Japan’s largest wind turbine gearbox manufacturer Ishibashi faces a familiar challenge in manufacturing wind turbine gearboxes - ensuring the reliability and longevity that is critical to their customer’s return on investment. At the core of Ishibashi’s testing procedure is Brüel & Kjær’s PULSE analyzer and - ...

Axisymmetric vibration analysis of isotropic circular plate with attached annular piezoceramic plate

by Inderscience Publishers  (Jan. 22, 2013)

An axisymmetric vibration analysis of an isotropic circular plate with a piezoceramic annular plate attached to it is presented. The annular plate is attached at the circular plate edge so that the radius of the circular plate is the inner radius of the annular plate. The piezoceramic annular plate is used as the radial in–plane load source. A ...

Staying Safe with Environmental Monitoring

by Soldata Ltd  (Oct. 21, 2012)

Geotechnical Instrumentation involves administering the earth and environment and it is hence that designers have made different frameworks to make the occupation simpler. These frameworks grab thousands upon much information that it orders and illuminates so they can concoct evidence. The places where it is necessary are the pollution chance ...
