RISComputational Fluid Dynamics Simulations of Aerodynamic Performance of Low-Pressure Axial Fans With Small Hub-to-Tip Diameter Ratio
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rotor-only ducted axial fans with small hub-to-tip diameter ratio are widely used in many branches of industry, especially for cooling and ventilation purposes. For such fans, extensive regions of backflow are present ...
Robust Fixed-Time Integral Sliding Mode Control of a Nonlinear Hydraulic Turbine Regulating System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hydraulic turbine regulating system (HTRS) plays an important role in the safe and stable operation of hydropower stations. In this paper, a fixed-time integral sliding mode controller (FTISMC) is designed to make the ...
Design for High Efficiency of Low-Pressure Axial Fans With Small Hub-to-Tip Diameter Ratio by the Vortex Distribution Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Axial fans with a small hub-to-tip diameter ratio (HTR) are widely used in industry, especially for cooling and ventilation purposes. The optimization of their aerodynamic performance is important, for which the vortex ...
Reverse-Rapidly Exploring Random Tree Based Path Planning With Insertion Pose Finding for Robot-Assisted Flexible Needles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. In percutaneous puncture surgery, achieving precise access to the target region while avoiding anatomical obstacles remains a critical challenge. However, due to the nonholonomic constraints of the needle, planning ...
Integrated Control of Thermally Induced Vibration and Quasi Static Deformation of Space Truss
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamic vibration and quasistatic deformation will occur simultaneously for flexible space structures subjected to sudden thermal loads. In this paper, the integrated controller based on modified positive position feedback ...
Effects of Cross-Sectional Size and Shape on the Longitudinal Tensile and Anchoring Properties of CFRP Cables
Publisher: American Society of Civil Engineers
Abstract: Carbon fiber–reinforced polymer (CFRP) is very suitable for use as a prestressed cable and can replace conventional steel cables in cable roofs. In engineering practice, the anchoring length increases rapidly as the ...
Refined Separation Effect on the Mesoscale Morphological Characteristics of Reclaimed Aggregate Using CT Scanning Technology
Publisher: American Society of Civil Engineers
Abstract: AbstractEfficient utilization of reclaimed asphalt pavement (RAP) is a significant way to
improve resource conservation and reduce energy consumption. Refined separation (RS)
technology can reduce the variability of RAP ...
Locating Water Supply Pipeline Leaks Using Multivariate Variational Mode Decomposition and Multichannel Singular Spectrum Analysis
Publisher: American Society of Civil Engineers
Abstract: AbstractEnvironmental noise interference makes it difficult to extract leakage features from
vibration signals during pipeline leaks, resulting in inaccurate leak localization.
In order to reduce noise in the signal, improve ...
Shear Behavior Analysis of Grouped Stud Connectors Embedded in Ultrahigh-Performance Concrete for Composite Bridges
Publisher: American Society of Civil Engineers
Abstract: AbstractIn this study, push-out tests were conducted on two types of stud connectors (seven
sets of grouped studs and one set of single studs) to study the shear behavior of
grouped stud connectors in steel–ultrahigh-performance ...
Experimental and Numerical Analysis of Steel-Block Shear Connectors in Assembled Monolithic Steel–Concrete Composite Beams
Publisher: American Society of Civil Engineers
Abstract: To study the shear behavior of the steel-block shear connector (SBSC) welded on a steel beam, eight push-out experiments were conducted, including two specimens with cast-in-place (CIP) concrete decks and six specimens ...
