RISOn the Joint Velocity Jump for Redundant Robots in the Presence of Locked-Joint Failures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The joint velocity jump for redundant robots in the presence of locked-joint failures is discussed in this paper. First, the analytical formula of the optimal joint velocity with minimum jump ...
Optimizing Vehicle and Pedestrian Trade-Off Using Signal Timing in Intersections with Center Transit Lanes
Publisher: American Society of Civil Engineers
Abstract: The construction of exclusive bus lanes is a strategy for giving priority to buses and improving the efficiency of the urban transportation system, and for that purpose, center transit lanes are an important type of transit ...
Multi-Point Path Planning Algorithm for a Mobile Robot With Composite Moving Costs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multi-point path planning problem is a classic problem of the mobile robot. The present research is concerned with solving the shortest path. In some realistic applications, the shortest path length is not always the ...
Buckling of Plates with Arbitrary Geometric Configurations via the Discrete Ritz Method
Publisher: American Society of Civil Engineers
Abstract: A discrete Ritz method (DRM) is presented for buckling analysis of plates with arbitrary geometric configurations employing the concept of representing structural energy with global variable stiffness. In the DRM approach, ...
Planar Deployable Linkage and Its Application in Overconstrained Lift Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the application of a planar deployable structure with screw theory and discusses its possible applications in overconstrained lift platforms via calculating its stiffness. These platforms are all ...
Bionic Flapping Mechanism of the Wings of a Cursorial Dinosaur Robot for Estimating Its Lift and Thrust
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We estimated the lift and thrust of the proto-wings of the dinosaur Caudipteryx, a close relative of birds, using both theoretical and experimental approaches. Our experiments utilized a newly reconstructed flapping wing ...
The Current-Carrying Tribological Properties of Cu/Graphene Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Excellent current-carrying tribological properties including the low-friction, high anti-wear, high current-carrying efficiency, and stability are important for the current-carrying application in transmitting electrical ...
Independent Suspension of Invariable Alignment Parameters by Using Flexible Links With Anisotropic Elasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates an independent suspension with invariable alignment parameters by using flexible links of anisotropic elasticity. It focuses on the synthesis of elasticity of compliant flat links and establishes ...
On the Bias in Simulated ENSO SSTA Meridional Widths of CMIP3 Models
Publisher: American Meteorological Society
Abstract: he fidelity of coupled climate models simulating El Niño?Southern Oscillation (ENSO) patterns has been widely examined. Nevertheless, a systematical narrow bias in the simulated meridional width of the sea surface temperature ...
Design and Folding/Unfolding Dynamics of an Over-Constrained Airplane's Landing Gear With Four Side Stays
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper introduces the design of a specific landing gear retraction system presenting a mechanism with four redundant side stays and examines its dynamic behavior during the folding and unfolding processes. First, a ...
