Lie Group Based Type Synthesis Using Transformation Configuration Space for Reconfigurable Parallel Mechanisms With Bifurcation Between Spherical Motion and Planar Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates novel reconfigurable parallel mechanisms with bifurcation between planar subgroup SE(2) and rotation subgroup SO(3) based on a transformation configuration space. Having recollected necessary ...
A Novel Evaluation Index and Optimization Method for Ankle Rehabilitation Robots Based on Ankle-Foot Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ability of ankle rehabilitation robots to accurately mimicking the actual human ankle motion is an important judgment basis for robot-assisted rehabilitation training. This paper proposes an evaluation index and mechanism ...
Variable Pivot Gait Based a Novel Dynamics Correction Method for Human Lower Limbs Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rationality of gait analysis directly affects the dynamics of human lower limbs in the sagittal plane, and recent studies on gait stage redivision lack the stage when both feet are not in complete contact with the ...
Modeling of Aerodynamically Generated Noise From Wind Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A semiempirical acoustic generation model based on the work of Brooks, Pope, and Marcolini [NASA Reference Publication 1218 (1989)] has been developed to predict aerodynamic noise from wind ...
Cavitation Erosion of Cobalt Alloy Coatings Containing Tungsten Carbide Particles in Hydrochloric and Sulphuric Corrosive Media
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cavitation erosion tests of composite coatings based on vacuum fusion sintered cobalt alloy containing tungsten carbide particles were carried out in 30 percent HCl and 50 percent H2 SO4 ...
Mechanism Analysis of Subgrade Frost Heaving in Seasonally Frozen Regions
Publisher: American Society of Civil Engineers
Abstract: To elucidate the frost heaving mechanism of subgrade, as well as reduce cracking, subsidence, and mudding due to water freezing and thawing in seasonally frozen regions, temperature sensors were embedded in the subgrade ...
Opposite Variability of Indonesian Throughflow and South China Sea Throughflow in the Sulawesi Sea
Publisher: American Meteorological Society
Abstract: ased on a high-resolution (0.1° ? 0.1°) regional ocean model covering the entire northern Pacific, this study investigated the seasonal and interannual variability of the Indonesian Throughflow (ITF) and the South China ...
Characterization of Creeping and Shape Memory Effect in Laser Sintered Thermoplastic Polyurethane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermoplastic polyurethane (TPU) powders were successfully processed in a selective laser sintering (SLS) system. The laser-sintered polyurethane products with viscoelastic behaviors exhibit high flexibility and elongation ...
Critical Buckling Strains in Thick Cold-Formed Circular-Hollow Sections under Cyclic Loading
Publisher: ASCE
Abstract: Contrary to the large dataset of test results exploring the monotonic bending response of steel tubes, the corresponding dataset of cyclic bending tests remains very small. Seven compact and semicompact S355J2H cold-formed ...
Novel Approach to Determine Spinning Satellites’ Attitude by RCS Measurements
Publisher: ASCE
Abstract: This paper proposes a novel approach for determining the three-dimensional (3D) attitude of on-orbit satellites in a spin condition using radar cross-section (RCS) measurements. The core idea of the approach lies in the ...
