RISInternal Wind Pressures and Buckling Behavior of Large Cylindrical Floating-Roof Tanks Under Various Liquid Levels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, two practical large cylindrical floating-roof tanks with diameters of 60 m and 100 m are selected as research objects. Wind pressures on the internal wall of tank shells under various liquid levels are ...
Theoretical and Experimental Study on Active Stiffness Control of a Two-Degrees-of-Freedom Rope-Driven Parallel Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rope-driven mechanisms with the characteristics of high speed, low inertia, and high precision are widely utilized in numerous fields. Stiffness is an important indicator to illustrate the precision and compliance of the ...

Modeling and Verification of a RANCF Fluid Element Based on Cubic Rational Bezier Volume
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This investigation is focused on developing a novel three-dimensional rational absolute nodal coordinate formulation (RANCF) fluid element based on cubic rational Bezier volume. The new fluid element can describe liquid ...
Multi-Branch Cellular Space Robot Mechanism Design and Climbing Behavior Research
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current space engineering projects such as large space structure erection and spacecraft maintenance tasks require robots with space truss climbing capability. To adapt to the complex climbing environment, this paper ...
A Hyperbolic Contact Surface Winkler Contact Force Model for Spherical Clearance Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Spherical clearance joints are essential for the successful deployment of space structures. When the clearance is small enough, the contacts will be considered conformal contact, which probably leads to inaccuracies in ...
Experimental and Numerical Investigation of Deep Surge in a Centrifugal Compressor With Vaned Diffuser and Piping System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Deep surge is a violent flow instability that affects the flow field throughout the entire compression system, potentially leading to performance deterioration and mechanical failures in compressors. A deeper ...
Crack-Parallel Stress Effects in Soft Material Fracture: Insights From Gap Tests and the Microplane Modeling Perspective
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Fracture in soft materials such as elastomers and biological tissues is traditionally characterized by a constant fracture energy, independent of nonsingular stresses. Recent advances in stiff quasi-brittle and ...
Humidification Effects of Proton Exchange Membrane Fuel Cell With Conventional and Interdigitated Flow Field
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A threedimensional and steadystate model was developed to explore the effects of fuel gas humidification on cell performance for conventional and interdigitated flow fields in proton exchange membrane fuel cells (PEMFCs). ...
