Abstract This research activity aims to develop new cycling gloves. A first step was focused on the definition of functional requirements through user centred design methods. Since vibrations coming hand-arm system a cyclist have considerable effect second concentrated analysis in road cycling. The paper shows results laboratory tests executed for three different hand sizes, frequency ranges, w...

Gear is one of critical transmission elements, found its wide applications in small, medium and large machineries. It is well proved that vibration signals acquired from a rotating machine comprise of the dynamic information about the health condition of the rotating machine. This paper uses vibration signals acquired from machinery comprising of gears in good and simulated faulty conditions fo...

Results are presented from a new algorithm developed for separating the vibration signals from a planetary gear system into separate signals attributable to each planet gear. From the separate signals, time synchronous average signals are produced for each planet gear and for the sun gear meshing with each planet gear. Assessments of the individual planet and sun gears can be made from these ne...

In this work the invariant imbedding method has been used to develop an algorithm to study the torsional vibration of non-uniform systems. The algorithm is based on the propagation, reflection, and transmission of waves in a stepped waveguide and is part of a procedure to transform two-point boundary value problems in initial value problems. Based on this approach, a continuous model has been d...

Directing at the problem of torsional vibration occurred in the start-up procedures of long shaft drive transmission existed in printing equipment, we raised a variable structure control method based on Variable parameters fuzzy. The method not only displays feature of traditional non-linear variable structure control like nondeference derivation, planning the dynamic process and good capacity ...

In this study, tapered polymer fiber sensors (TPFSs) have been employed to detect the vibration of a reinforced concrete beam (RC beam). The sensing principle was based on transmission modes theory. The natural frequency of an RC beam was theoretically analyzed. Experiments were carried out with sensors mounted on the surface or embedded in the RC beam. Vibration detection results agreed well w...
