Abstract:
Large diamond circular saw blade is a plane with large diameters and thin thick, so there are serious vibration problems in the process of sawing stone under the high-speed. By using the force hammer producing incentive experiment method, the effect of the inner and outer diameters to the vibration modal and frequency of diamond circular saw blade are analyzed. Through comparing inner and outer diameter, it can be found that the inner diameter has greater influence on the natural frequency, while the outer diameter has greater influence on the amplitude. The result supplies reliable data for e

Abstract:
The deformation behavior of microtubes during hollow sinking was investigated to clarify the mechanism of the excessive thinning of their outer diameters. Stainless-steel, copper, and aluminum alloy tubes were drawn without an inner tool to evaluate the effect of Lankford values on outer diameter reduction. Drawing stress and stress-strain curves were obtained to evaluate the yielding behavior during hollow sinking. The observed yielding behavior indicated that the final outer diameter of the drawn tube was always smaller than the die diameter due to the uniaxial tensile deformation starting f

The average diameters of the fullerene particles in C60-pyridine colloid solution after irradiation were characterized by dynamic light scattering. After light irradiation, an outer separated layer of pyridine surrounds the fullerene particles because of the charge transfer complexes formation. The mean ratios of inner

We performed bending tests on single-crystal nanotubes composed of fullerene C70molecules byin situtransmission electron microscopy with measurements of loading forces by an optical deflection method. The nanotubes with the outer diameters of 270–470 nm were bent using simple-beam and cantilever-beam loading by the piezomanipulation of silicon nanotips. Young's modulus of the nanotubes increased from 61 GPa to 110 GPa as the outer diameter decreased from 470 nm to 270 nm. Young's modulus was estimated to be 66% of that of single-crystal C60nanotubes of the same outer diameter.

Abstract:
Welded hollow spherical joint is widely used in large-span spatial structures due to its simple structure, clear mechanical behavior and convenient connection. However, a large number of sphere-pipe connection welds at the joints will inevitably produce complex welding residual stress, which will have adverse effects on the stiffness of the joints and the overall safety of the structure. Focusing on the sphere-pipe connection welds on the hollow spherical joints, this paper keeps track of the whole process of sphere-pipe welding, analyzes and summarizes the distribution law and specific distri

FINITE ELEMENT SIMULATION FOR ULTRA-HIGH-PERFORMANCE CONCRETE-FILLED DOUBLE-SKIN TUBES EXPOSED TO FIRE. The Hong Kong Institute of Steel Construction, 2022. http://dx.doi.org/10.18057/icass2020.p.263.

Abstract:
Ultra-high-performance concrete (UHPC) or ultra-high-strength concrete (UHSC) are alternatively used to reduce construction materials, thereby achieving more sustainable constructions. Moreover, engaging the advantages of concrete cores and outer steel tubes in concrete-filled steel tubes (CFST) or ductile concrete-filled double-skin tubes (CFDST) is of great interest for the better performance of such members under fire. Nevertheless, current design provisions do not provide design models for UHPC-filled double-skin tubes under fire, and existing finite-element (FE) methodologies available in

STABILITY PERFORMANCE AND WIND TUNNEL TEST OF STEEL HYPERBOLIC COOLING TOWER CONSIDERING SKINNED EFFECT. The Hong Kong Institute of Steel Construction, 2023. http://dx.doi.org/10.18057/ijasc.2023.19.3.10.

Abstract:
With the development of industry, cooling towers play a very important role in thermal power generation, and steel cooling towers are being used more widely. The surface of cooling towers is covered with profiled panels, and the skinned effect on the mechanical performance and stability of the structure should be considered. At present, most studies on steel cooling towers have not considered the skinned effect. In steel cooling towers, the skin panels are usually connected to members by self-tapping screws., the shearing test of self-tapping screw connection is carried out considering differe
