RISA Reconfigurable 6R Linkage With Six Motion Modes and Three Topological Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a new reconfigurable 6R linkage is obtained by combining two identical equilateral Bennett linkages arranged in a planesymmetric manner, and a detailed kinematic analysis is conducted which shows that there ...
Investigation of the Top-Down Cracking Propagation Behavior of Flexible Asphalt Pavement Based on Numerical Modeling and Full-Scale Accelerated Pavement Tests
Publisher: American Society of Civil Engineers
Abstract: Top-down cracks (TDCs) and their associated secondary damage have emerged as critical factors limiting the long-term service performance of flexible asphalt pavements. The mechanisms underlying various types of TDCs, ...
Astronomic Positioning and Orientation Method for Inhomogeneous Stellar Distributions
Publisher: ASCE
Abstract: Astronomic positioning and orientation can be used to obtain the astronomic longitude and latitude of a station and the astronomic azimuth of a ground target by observing stars. The results of the positioning and orientation ...
A Sensitivity Study of an Effective Aerodynamic Parameter Scheme in Simulating Land–Atmosphere Interaction for a Sea–Land Breeze Case Around the Bohai Gulf of China
Publisher: American Meteorological Society
Abstract: AbstractNumerical simulations of the atmospheric boundary layer require careful representation of the surface heterogeneity, which involves the upscaling parameterization scheme for the heterogeneous surface parameters. ...
Mechanical Properties of Polyester-Coated Fabric Membrane Material Subjected to Uniaxial Loading at Elevated Temperatures
Publisher: ASCE
Abstract: Polyester-coated fabric has been widely used in membrane structures. However, the mechanical properties of polyester-coated fabric at elevated temperatures have not been well studied, limiting its applications in the ...
