Reliability Assessment of Mechanical Components Using Fuzzy-Set Theory
Publisher: The American Society of Mechanical Engineers (ASME)
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. ...
Variable Structure Control of a Pneumatic Actuator
Publisher: The American Society of Mechanical Engineers (ASME)
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. ...
PEM Fuel Cell Dynamic Model With Phase Change Effect
Publisher: The American Society of Mechanical Engineers (ASME)
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 ...
Granular Damping in Forced Vibration: Qualitative and Quantitative Analyses
Publisher: The American Society of Mechanical Engineers (ASME)
