Configuration design and accuracy analysis of a novel magnetorheological finishing machine tool for concave surfaces with small radius of curvature

Henan Liu,Ming-Jun Chen,Bo Yu,Zhen Fang 대한기계학회 2016 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.30 No.7

Magnetorheological finishing (MRF) is a computer-controlled deterministic polishing technique that is widely used in the production of high-quality optics. In order to overcome the defects of existing MRF processes that are unable to achieve concave surfaces with small radius of curvature, a configuration method of a novel structured MRF machine tool using small ball-end permanent-magnet polishing head is proposed in this paper. The preliminary design focuses on the structural configuration of the machine, which includes the machine body, motion units and accessory equipment, and so on. Structural deformation and fabrication accuracy of the machine are analyzed theoretically, in which the reasonable structure sizes, manufacturing errors and assembly errors of main structural components are given for configuration optimization. Based on the theoretical analysis, a four-axes linkage MRF machine tool is developed. Preliminary experiments of spot polishing are carried out and the results indicate that the proposed MRF process can achieve stable polishing area which meets requirement of deterministic polishing. A typical small-bore complex component is polished on the developed device and fine surface quality is obtained with sphericity of the finished spherical surfaces 1.3 μm and surface roughness Ra less than 0.018 μm.

The purpose of this in vitro study was to evaluate the effect of surface defects and cross-sectional configuration of NiTi rotary files on the fatigue life under cyclic loading. Three NiTi rotary files (K3^(TM), ProFile®, and HERO 642®) with #30/.04 taper were evaluated. Each rotary file was divided into 2 subgroups: control (no surface defects) and experimental group (artificial surface defects). A total of six groups of each 10 were tested. The NiTi rotary files were rotated at 300rpm using the apparatus which simulated curved canal (40 degree of curvature) until they fracture. The number of cycles to fracture was calculated and the fractured surfaces were observed with a scanning electron microscope. The data were analyzed statistically. The results showed that experimental groups with surface defects had lower number of cycles to fracture than control group but there was only a statistical significance between control and experimental group in the K3^(TM) (p〈0.05). There was no strong correlation between the cross-sectional configuration area and fracture resistance under experimental conditions. Several of fractured files demonstrated characteristic patterns of brittle fracture consistent with the propagation of pre-existing cracks. This data indicate that surface defects of NiTi rotary files may significantly decrease fatigue life and it may be one possible factor for early fracture of NiTi rotary files in clinical practice.

Adsorption of CO molecules on the Si(111)-(7x7) surface

Seo, E.,Eom, D.,Hyun, J.M.,Kim, H.,Koo, J.Y. North-Holland Pub. Co 2017 Surface science Vol.656 No.-

Adsorption of CO molecules on Si(111)-(7x7) is investigated by using scanning tunneling microscopy (STM) and density-functional theory calculations. The most reactive site on the Si(111)-(7x7) surface is the corner adatom in the faulted half unit (FHU), followed by the center adatom in the FHU. The initial sticking probability of CO molecules on Si(111)-(7x7) at room temperature (RT) is estimated to be ~4x10<SUP>10</SUP> molecules/(cm<SUP>2</SUP>.Langmuir), which is comparable with that on Si(001)-(2x1). From the experiments and theoretical calculations, the adsorption of CO molecules are found to occur on Si adatoms either in the upright on-top configuration or in the back-bond inserted configuration, while the adsorption on the rest and the corner hole atoms (which are theoretically probable) are not observable using STM due to their low-lying geometries. Though the sticking probability is very low, every surface dangling bond on the surface can bind strongly with the C atom of a CO molecule even at temperatures higher than RT.

Aerodynamic coefficients of inclined and yawed circular cylinders with different surface configurations

Lin, Siyuan,Li, Mingshui,Liao, Haili Techno-Press 2017 Wind and Structures, An International Journal (WAS Vol.25 No.5

Inclined and yawed circular cylinder is an essential element in the widespread range of structures. As one of the applications, cables on bridges were reported to have the possibility of suffering a kind of large amplitude vibration called dry galloping. In order to have a detailed understanding of the aerodynamics related to dry galloping, this study carried out a set of wind tunnel tests for the inclined and yawed circular cylinders. The aerodynamic coefficients of circular cylinders with three surface configurations, including smooth, dimpled pattern and helical fillet are tested using the force balance under a wide range of inclination and yaw angles in the wind tunnel. The Reynolds number ranges from $2{\times}10^5$ to $7{\times}10^5$ during the test. The influence of turbulence intensity on the drag and lift coefficients is corrected. The effects of inclination angle yaw angle and surface configurations on the aerodynamic coefficients are discussed. Adopting the existed the quasi-steady model, the nondimensional aerodynamic damping parameters for the cylinders with three kinds of surface configurations are evaluated. It is found that surface with helical fillet or dimpled pattern have the potential to suppress the dry galloping, while the latter one is more effective.

Sensitivity Evaluation of a Multi-Layered Heterostructure Blue Phosphorene/MoS 2 Surface Plasmon Resonance Based Fiber Optic Sensor: A Simulation Study

Sachin Singh,A. K. Sharma,Pooja Lohia,D. K. Dwivedi 한국전기전자재료학회 2022 Transactions on Electrical and Electronic Material Vol.23 No.3

In this study, an angular interrogation technique has been used for modeling a highly sensitive surface plasmon resonance (SPR)based biosensor. The large surface area of the heterostructure of the blue phosphorene (BP/MoS 2 ) layer facilitates the biomolecules absorption. A four-layer Kretschmann model of the SPR biosensor containing the BP/MoS 2 heterostructure with a gold layer is proposed. Compared to the traditional gold fi lmbased SPR biosensors, the sensitivity of the proposed SPR biosensor has been signifi cantly improved. An enhanced sensitivity 224.57°/RIU has been achieved by optimizing the proposed structure with 50 nm thick gold layer and a monolayer of heterostructure BP/MoS 2 with a thickness of 0.75 nm. Moreover, the proposed BP/MoS 2 heterostructure off ers extremely small FWHM, high detection accuracy, and highquality factor parameters. The highest sensitivity of 252°/RIU was found with two-layers of BP/MoS 2 heterostructure confi guration. It is observed that, compared to previously reported sensitivity, the proposed SPR biosensor shows better results.

In order to rpovide proper SMT design criteria in a systematic way, a mathematical formulation has been developed to predict the configuration of the solder fillet formed between the gullwing type lead and rectangular pad. Effects of SMT design parameters such as the solder volume and pad dimension on the solder profile are investigated using the FEM that calculates the 3D configuration by minimizing the energy due to surface tension and gravity in the equilibrium state. Design criteria of QFP and SOP are illustrated by plotting the acceptable range of the solder volume with respect to the length and width ratios of the pad and lead. The results show that the acceptable design range increases with increase in the pad length and width. The pad length has more significant effects on design criteria compared with the pad width, and Bond number can be utilized to predict the joint quality.

무미익 형상 비행체의 조종면 힌지모멘트 측정을 위해 1/5 축소 하프 모델을 사용하여 조종면의 힌지모멘트를 측정하는 시험을 수행하였다. 시험변수로서 받음각, 조종면(In-Board:IB, Mid-Board:MB, Out-Board:OB, Spoiler) 변위를 선정하였으며 각 조종면의 힌지모멘트를 측정하여 힌지모멘트 계수를 도출하였다. IB 변위는 MB, OB의 힌지모멘트에 영향을 미치며, MB는 OB에, OB는 MB에, SP는 MB, OB에 영향을 미침을 각각 확인하였다. 추가로 MB의 뒷전에 웨지 적용 시와 조종면-주익 사이 공간 밀봉 시에 힌지모멘트에 대한 영향을 조사하였다. 본 풍동시험 결과 및 분석자료는 제안된 람다형 날개 형상 무인기 조종면의 조종력 예측 및 제어기 설계에 매우 유용하게 활용될 것이다. A wind tunnel test which measures the hinge moment acting on the control surfaces of a lambda wing configuration UAV is carried out using a newly developed moment balance and a 1/5 scaled half wind tunnel model. The hinge moment is measured while varying the angle of attack and the control surfaces(In-Board:IB, Mid-Board:MB, Out-Board:OB, Spoiler) deflection angle conditions. The results show that IB deflection has influence on the hinge moment measurements of MB and OB, whereas OB deflection on those of MB, and SP deflection on those of MB and OB, respectively. The present results would be useful in predicting control force and designing control system of blended-wing-body configuration vehicle.
