Characterization and Attenuation of Sandwiched Deadband Problem Using Describing Function Analysis and Application to Electrohydraulic Systems Controlled by Closed-Center Valves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Unlike input deadband, the sandwiched deadband between actuator and plant dynamics is very difficult to be explicitly compensated for due to the proceeding actuator dynamics whose effect may not ...
Spatiotemporal Complexity Analysis of Daily Precipitation in a Changing Environment in Heilongjiang Province, China
Publisher: American Society of Civil Engineers
Abstract: Complexity analysis is an important tool for research on water resources. Although physical methods and quantitative detection are typically used to explore system complexity, this study uses a method combining probabilistic ...
Experimental and Numerical Investigation on Filling Roll Bending of Aluminum Alloy Integral Panel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Integral panels are widely used in aerospace industries. A filling roll bending process is proposed to form integral panels. Filling roll bending experiments of aluminum alloy integral panels ...
Tube Transverse Pitch Effect on Heat/Mass Transfer Characteristics of Flat Tube Bank Fin Mounted With Vortex Generators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For one heat exchanger model of three-row flat tube bank fin mounted with vortex generators (VGs), the effect of transversal tube pitch on heat/mass transfer performance was investigated by the ...
Axial Compressive Behavior of Square CFST Columns through Direct Measurement of Load Components
Publisher: American Society of Civil Engineers
Abstract: A number of experimental and analytical studies have been conducted on the axial compressive behavior of square concrete-filled steel tubular (CFST) columns, but there still exist several controversies on this issue because ...
Surface Modification of Basalt Aggregate by Coupling Agent to Improve the Interfacial Adhesion with Asphalt Binder
Publisher: ASCE
Abstract: The surface performance of basalt aggregate shows a great influence on the interfacial adhesion between basalt aggregate and asphalt binder and further affects the moisture stability of the asphalt mixture. To improve the ...
Effect of the Key Geometry and Flow Parameters on Discharge Coefficient of Laidback Fan-Shaped Hole Under Coolant Crossflow Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A laidback fan-shaped hole is commonly used due to its superior lateral film coverage. Its discharge coefficient is significantly influenced by internal crossflow owing to its complex geometrical structure. In this paper, ...
