RISNumerical Simulation and Experimental Research on the Effect of Flow Regimes for Refrigeration Performance of Wave Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wave rotors exchange energy through the interaction of fluids with different pressures to produce a cooling effect without the application of mechanical parts, which makes them suitable for the complex flow field environments. ...
Hysteretic Modeling of Unbonded Posttensioned Precast Segmental Bridge Columns with Circular Section Based on Cyclic Loading Test
Publisher: American Society of Civil Engineers
Cyclic Loading Test of Unbonded and Bonded Posttensioned Precast Segmental Bridge Columns with Circular Section
Publisher: American Society of Civil Engineers
Abstract: Four 1/4-scale precast segmental bridge columns (PSBC) with different reinforcement types and arrangements and one monolithic reference column (MRC) were designed and tested under cyclic quasi-static loading. Both UPC (PSBC ...
An Equivalent-Plane Cross-Coupling Position Control for Contour-Accuracy Improvement in Three-Axis Free-Form Contour Following Tasks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To reduce the contouring errors in computer-numerical-control (CNC) contour-following tasks, the cross-coupling controller (CCC) is widely researched and used. However, most existing CCCs are well-designed for two-axis ...
A Five-Axis Dual NURBS Interpolator With Constant Speed at Feedrate-Sensitive Regions Under Axial Drive Constraints
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: In the five-axis machining, the dual nonuniform rational B-spline (NURBS) interpolator performs better than the conventional linear interpolator in improving machining efficiency and quality. However, a successful dual ...
Mechanical Layout Optimization for Curvy Conformal Electronics With Multilayered Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Curvy conformal electronics offer broad application potential by integrating diverse multilayered structural components onto target curvy surfaces. The layout design of multilayered structures is crucial for ...
An Optimization Method for Valve Seat Contour to Improve the Sealing Performance of Cryogenic Butterfly Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Triple-offset butterfly valves are manufactured under standard temperature conditions. During cryogenic service, critical sealing structures undergo uneven deformation due to thermal contraction. This leads to ...
