Approximately 58% of wire failures are caused by slippage and fracture electrical connectors, the crimping quality analysis connectors is based on equivalent cross-sectional stiffness. First, a JL/GLA 400/35 steel cord aluminum strand NY-400/35 strain clamp selected to fabricate 26 groups specimens with different pipe penetration depths, opposite edge distances, inner diameters tube, die widths...

The use of thin-walled structures as impact energy absorbers are well known. thin aluminum cylinder tube is a good absorber. However, the energy-absorbing design must also have sufficient toughness. In this research, we made modifications to improve performance tube. cylinder's modification prepared by adding four grooves along wall in axial direction. Numerical modeling was carried out using f...

Shock tubes have been widely used since the 1950s to study physical phenomena such as shock waves, combustion chemistry, and the response of materiel to blast loading. Recently, laboratory-scale shock tubes driven by oxy-acetylene were described. It was estimated that these shock tubes would not have a significant “jet effect” of expanding gases following the shock front because the combustion ...

The measurement of total mercury in flue gas based on an economical aluminum matrix sorbent was developed in this paper. A sorbent trap consisted of three tubes was employed to capture Hg from flue gas. Hg trapped on sorbent was transferred into solution by acid leaching and then detected by CVAAS. Hg adsorbed on sorbent was recovered completely by leaching process. The 87.7% recovery of Hg in ...

The Rotary-Draw Bending (RDB) process is a distinguished process employed for the precision cold bending of a hollow tube with small radius bends using Numerical Control (NC) machines. This research presents an analytical model based on the power law hardening model for the RDB processing of rectangular thin tubes. Based on the constraints of the tube in the dies and its thinness, the plane str...

Determination of the half-value layer (HVL) and quarter-value layer (QVL) values is not an easy task in x-ray computed tomography (CT), because a nonrotating x-ray tube must be used, which requires the assistance of service engineers. Therefore, in this study, we determined the accuracy of the lead-covered case method, which uses x-rays from a rotating x-ray tube, for measuring the HVL and QVL ...

Electromagnetic forming is a high energy rate forming process in which an electromagnetic Lorentz body force is used for deformation of products.  In this article, electromagnetic forming process was simulated for the assembly of parts as an innovative method.  The effect of important process parameters such as discharge energy, radius and width of rectangular groove on the strength of the asse...
