RISCondition Monitoring the Drive Train of a Direct Drive Permanent Magnet Wind Turbine Using Generator Electrical Signals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The benefit of wind turbine (WT) can be significantly improved through a wellorganized conditionbased maintenance strategy. However, such a target has not been fully achieved today. One of the major reasons is lack of an ...
Wind Turbine Condition and Power Quality Monitoring by the Approach of Fast Individual Harmonic Extraction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Increasing deployment of wind turbines requires efficient condition monitoring to ensure the safety and availability of these machines. Grid code also requests the operator to enhance the monitoring of the quality of the ...
An Advanced Strategy for Detecting Impulses in Mechanical Signals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The appearance of overlapping in the results derived by continuous wavelet transform (CWT) smears the spectral features and makes the results difficult to interpret. This will significantly affect ...
Analytical Solution of Heat Exchange in Typical Electrocaloric Devices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To date, most of electrocaloric devices reported can be simplified as a multilayer structure in which thermal source and sink are different materials at two ends. The thermal conduction in the multilayer structure is the ...
Investigation of Fatigue Strength of Welded Tube-to-Tubesheet Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The tube-to-tubesheet joint of heat exchangers is an important aspect in the design and fabrication process. This paper discusses the fatigue strength of welded tube-to-tubesheet joint under a ...
Shear Behavior of Dry Joints with Castellated Keys in Precast Concrete Segmental Bridges
Publisher: American Society of Civil Engineers
Abstract: Precast concrete segmental bridges with dry joints have the advantages of rapid construction speed and low cost. The shear strength and shear behavior of dry joints with castellated keys in precast concrete segmental bridges ...
Unique Design of Pressure Vessel With Tooth-Locked Quick-Actuating Closures Based on Finite Element Model Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel method is developed for the design of pressure vessels with tooth-locked quick-actuating closures by considering the contact between the teeth and utilizing the surface-to-surface contact model with contact element ...
Buckling of Externally Pressurized Toroidal Shell With Stiffened Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The buckling characteristics of toroidal shells with closed circular cross sections loaded with a static external pressure were investigated. Eight toroidal shell test models were developed: two ribless, two semicircular ...
Design and Fabrication of Leadless Package Structure for Pressure Sensors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Silicon piezoresistive pressure sensors can only operate below 125 °C due to the leakage current of the PN junction. However, silicon-on-insulator (SOI) high-temperature pressure sensors use SiO2 for total dielectric ...
Optimization of Single-Chamber Air-Cathode Microbial Fuel Cells for Penoxsulam Degradation and Electricity Generation
Publisher: American Society of Civil Engineers
Abstract: AbstractAddressing the environmental risks posed by the persistence of penoxsulam, a widely
used herbicide, microbial fuel cells (MFCs) offer a promising bioelectrochemical approach
for simultaneous pollutant degradation ...
