RISAnalytical Model for the Characterization of the Guiding Zone Tribotest for Tube Hydroforming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Common part failures in tube hydroforming include wrinkling, premature fracture, and unacceptable part surface quality. Some of these failures are attributed to the inability to optimize tribological ...
Preform Design for Tube Hydroforming Based on Wrinkle Formation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A two-stage preforming process based on wrinkle formation is developed for the tube hydroforming process to accumulate material in the forming zone, thus reducing the thinning rate and improving ...
Experimental Study on Mechanical Behavior of PBL Shear Connectors
Publisher: American Society of Civil Engineers
Abstract: Perfobond rib connectors (PBLs) are widely applied to transfer the shear force in steel-concrete composite members. To investigate the mechanical behavior of PBL shear connectors, push-out tests were carried out under ...
Precursor Circulation Features for Persistent Extreme Precipitation in Central-Eastern China
Publisher: American Meteorological Society
Abstract: sing a composite analysis, the typical precursor circulation configuration from the lower to the upper troposphere responsible for persistent extreme precipitation events (PEPEs) of double-blocking-high type in central-eastern ...
Mechanical Damage and Response of a Buried Steel Pipeline Under Subsurface Explosion Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Subsurface explosions seriously threaten the safety and reliability of buried oil and gas pipeline. In order to investigate the mechanical responses of buried steel pipeline under subsurface explosion load, a numerical ...
Real-Time Friction Error Compensation in Tube Hydroforming Process Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tube hydroforming (THF) is a metal-forming process that uses a pressurized fluid in place of a hard tool to plastically deform a given tube into a desired shape. In addition to the internal ...
The Equal Bending Strength Design of Space Curve Meshing Wheel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The space curve meshing wheel (SCMW) has been studied previously for small power transmission. To extend its application in conventional power transmission, the bending strength of the SCMW needs to be studied. In this ...
Study Effect of Antiturbulence Additives on Hydraulic Efficiency in Oil Pipelines by Disk Turborheometer
Publisher: ASCE
Abstract: To determine the efficiency of additives Necadd-447, M-FLOWTREAT, FLO-XL, and FLO-MXA, a method for conducting experiments and processing the obtained results is proposed in this paper. The hydraulic efficiency for all ...
Consistent Approximation of Fractional Order Operators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fractional order controllers become increasingly popular due to their versatility and superiority in various performances. However, the bottleneck in deploying these tools in practice is related to their analog or numerical ...
Mechanical and Functional Self-Healing Characteristics of Hot-Poured Crack Sealant Exploiting Dynamic Shear Rheometer and Low-Temperature Tensile Tester
Publisher: ASCE
Abstract: As a kind of asphaltic material, hot-poured sealant with initial aging or failure will gradually self-heal during the change of ambient in the actual service process, so as to restore its service performance to a certain ...
