RISPowerGen Gas Turbine Losses and Condition Monitoring: A Loss Data Based Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In situ condition monitoring (CM) is a crucial element in protection and predictive maintenance of large rotating PowerGen equipment, such as gas turbines or steam turbines. In this work, selected gas turbine loss events ...
Effect of Condition Monitoring on Risk Mitigation for Steam Turbines in the Forest Products Industry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Industry has been implementing condition monitoring (CM) for turbines to minimize losses and to improve productivity. Deficient conditions can be identified before losses occur by monitoring the equipment parameters. For ...
A Portable Passive Ankle-Foot Orthosis for Walking Propulsion and Drop-Foot Prevention
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Individuals with a drop-foot generally have issues of foot-slap and toe-drag, and ankle-foot orthoses (AFOs) have been developed for them to address the drop-foot gait. However, the currently available active AFOs usually ...
Modified First-Order Compound Function-Based Interval Perturbation Method for Luffing Angular Response of Dual Automobile Crane System With Interval Variables
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The accuracy of conventional crane engineering problems with bounded uncertainty is limited to cases where only first-order terms are retained. However, the impact of high-order terms on the luffing angular response (LAR) ...
Static Response Analysis of a Dual Crane System Using Fuzzy Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Static response analysis of a dual crane system (DCS) is conducted using fuzzy parameters. The fuzzy static equilibrium equation is established and two fuzzy perturbation methods, including the compound function/fuzzy ...
Implementation of Robotic Ankle–Foot Orthosis With an Impedance-Based Assist-as-Needed Control Strategy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a robotic ankle–foot orthosis (AFO) is developed for individuals with a paretic ankle, and an impedance-based assist-as-needed controller is designed for the robotic AFO to provide adaptive assistance. First, ...
Hybrid Compound Function/Subinterval Perturbation Method for Kinematic Analysis of a Dual-Crane System With Large Bounded Uncertainty
