RISResearch on the Accelerated Life Test Method for Gaskets and the Verification of the Accuracy of the Life Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bolted flanged connections are widely used in the petroleum and chemical industries. The gasket is the core component of bolted flanged connections. Accurate prediction of the gasket life is of great significance for the ...
An Improved Fourier–Ritz Method for Analyzing In-Plane Free Vibration of Sectorial Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A modified Fourier–Ritz approach is developed in this study to analyze the free in-plane vibration of orthotropic annular sector plates with general boundary conditions. In this approach, two auxiliary sine functions are ...
Regression Analysis of 3D Initial Geostress Field for Deep and Super-long Highway Tunnel
Publisher: American Society of Civil Engineers
Abstract: Based on the engineering-geological conditions and measured data of geostress in Cangling tunnel, each possible factor affecting the initial geostress field was discussed. On this basis, the established 3D simplified ...
Time-Varying Formation Control for Heterogeneous Planar Underactuated Multivehicle Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a distributed control approach for time-varying formation of heterogeneous planar underactuated vehicle networks without global position measurements. All vehicles in the network are modeled as generic ...
Semi-Analytical Model for the Transient Analysis of the Pressure in Vertically Fractured Wells in Reservoirs Considering the Influence of Natural Fractures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In addition to artificial fractures generated by hydraulic fracturing technology, natural fractures distributed in reservoirs will also affect the fluid flow process. To study the transient behavior of the pressure in fluid ...
Influence of Main Swirler Vane Angle on the Ignition Performance of TeLESS-II Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to balance the low emission and wide stabilization for lean premixed prevaporized (LPP) combustion, the centrally staged layout is preferred in advanced aero-engine combustors. However, compared with the conventional ...
Origami Crash Boxes Subjected to Dynamic Oblique Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The energy absorption capacity of origami crash boxes (OCB) subjected to oblique loading is investigated in the present study. A conventional square tube (CST) with identical weight is employed as benchmark. The comparative ...
New Analytic Free Vibration Solutions of Rectangular Thick Plates With a Free Corner by the Symplectic Superposition Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Seeking analytic free vibration solutions of rectangular thick plates without two parallel simply supported edges is of significance for an insight into the performances of related engineering devices and structures as ...
A Simplified Indirect Measuring Method for the Notch Stress in a Thin Cylindrical Shell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new simplified indirect measuring method (SIMM) is proposed for the notch stress of a circumferentially notched thin cylindrical shell by measuring the stresses away from the notch with the conventional ...
Lateral Earth Pressure Coefficient of Soils Subjected to Freeze–Thaw
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Artificial frozen soils (AFS) have been used widely as temporary retaining walls in strata with soft and water-saturated soil deposits. After excavations, frozen soils thaw, and the lateral earth pressure penetrates through ...
