Abstract: By applying the cumulative fatigue damage to the random process reliability problem, and the introduction of a proposed concept of unified equivalent stress mean level in fatigue life prediction, ...

Abstract: An approach to assessing the reliability of mechanical components, especially for pressure vessels and piping, is proposed in which the vagueness and fuzziness in variables have been considered. ...

Abstract: In an effort to overcome the nonlinerities associated with a pneumatic system the variable structure control (VSC) technique has been employed to control the position of a pneumatic actuator. ...

Abstract: In this research, a system-level dynamic model accounting for the phase change effect is developed for polymer electrolyte fuel cells (PEMFCs). This model can illustrate the complicated transient ...

Abstract: Granular damping is a passive vibration suppression technique which attenuates the response of a vibrating structure by the use of a granule-filled enclosure attached to or embedded in the ...

Abstract: Granular damping, which possesses promising features for vibration suppression in harsh environments such as in turbo-machinery and spacecraft, has been studied using empirical analysis and more ...

Abstract: This paper proposes a multi-mode vibration suppression scheme for rotationally periodic structures. Identical active-passive hybrid piezoelectric networks are applied on each of the substructures, ...

Abstract: Granular damping results from a combination of energy dissipation mechanisms including the impact and the friction between the vibrating structure and granules and among the granules. Although ...

Abstract: As damping reduction can potentially lead to performance enhancement in certain applications, a scheme based on the concept of piezoelectric circuitry that yields reduced damping effect in a ...

Abstract: Fault detection in complex mechanical systems such as wind turbine gearboxes remains challenging, even with the recently significant advancement of sensing and signal processing technologies. As ...
