Miniaturized Electronically Steerable Parasitic Array Antenna

Open Journal of Antennas and Propagation 2023年第1期11卷 1-10页

作者： Shafaq Kausar Ahmed Kausar Hani Mehrpouyan muhammad hadi Salahuddin Tariq Department of Electrical and Computer Engineering Boise State University Boise ID USA Arts & Science Division at University of Toronto Toronto Canada School of Engineering Ulster University Belfast United Kingdom Department of Electrical and Computer Engineering University of Texas at Dallas Richardson TX USA

In this article we propose a miniaturized dual-band electronically steerable parasitic array radiator (ESPAR) antenna. The antenna can generate up to two steerable beams. The beam-steering range of the proposed antenna is 360˚ in the azimuth plane. The antenna’s eual-band coverage includes the frequency ranges from 2.3 GHz to 2.53 GHz and from 2.9 GHz to 3.7 GHz. The antenna consists of six folded parasitic monopole elements surrounding an active conical element. The folded monopole element design offers three times lower antenna height than that of the conventional ESPAR antennas. The active element has conical shape and it is larger in length than the parasitic monopole elements, this enables the dual-band operation. Thus, the proposed design is not only smaller than the conventional ESPAR antennas but it also achieves dual-band operation. Despite its compact design, the antenna has a peak gain of 6.3 dBi, which is equivalent to the gain of conventional ESPAR antennas. These characteristics make the antenna a good candidate for next generation communication systems.

根据钢纤维混凝土具有较大变形和裂缝扩展能力的特点,建立了钢纤维混凝土环向伸长的表达式。在此基础上,将弹性力学理论、虚拟裂缝理论与钢纤维混凝土软化模型相结合,提出了钢筋与钢纤维混凝土黏结强度的计算方法,并进行了试验验证,同时分析了相对保护层厚度（混凝土保护层厚度与钢筋直径之比）、裂缝数量和钢筋直径对相对黏结强度（黏结强度与钢纤维混凝土抗拉强度之比）的影响。结果表明,钢筋与钢纤维混凝土相对黏结强度处于塑性状态解和部分开裂弹性状态解之间;钢纤维体积率在0.5%～1.5%时,随着黏结试件相对保护层厚度的增大和裂缝数量的增多,相对黏结强度增大;随着钢筋直径的增大,相对黏结强度减小。但当裂缝数量大于5或钢筋直径大于32 mm,裂缝数量和钢筋直径的变化对相对黏结强度的影响较小。

基于内贴应变片的钢筋与钢纤维混凝土局部黏结试件的拉拔试验,研究钢筋与不同强度钢纤维混凝土的黏结性能。通过对实测钢筋应变的分析,建立了以三次多项式表达的黏结应力分布函数,得到了各级荷载作用下钢筋与钢纤维混凝土黏结应力和相对滑移沿黏结区段的分布,进一步分析了钢纤维和混凝土强度对黏结性能的影响。结果表明,随钢纤维的体积率和混凝土强度的增大,黏结试件加载端附近的黏结应力提高,黏结应力极值总体向加载端靠拢;同时,加载端与自由端的滑移减小。最后,提出了能够较好反映钢筋与钢纤维混凝土受力过程的黏结-滑移关系模型。

Process development for green part printing using binder jetting additive manufacturing

Frontiers of Mechanical Engineering 2018年第4期13卷 504-512页

作者： hadi MIYANAJI Morgan ORTH Junaid muhammad AKBAR Li YANG Department of Industrial Engineering University of Louisville Louisville KY 40292 USA Department of Mechanical Engineering University of LouisvilleLouisville KY 40292 USA

Originally developed decades ago, the binder jetting additive manufacturing （B J-AM） process possesses various advantages compared to other additive manufacturing （AM） technologies such as broad material compat- ibility and technological expandability. However, the adoption of B J-AM has been limited by the lack of knowledge with the fundamental understanding of the process principles and characteristics, as well as the relatively few systematic design guideline that are available. In this work, the process design considerations for B J-AM in green part fabrication were discussed in detail in order to provide a comprehensive perspective of the design for additive manufacturing for the process. Various process factors, including binder saturation, in- process drying, powder spreading, powder feedstock characteristics, binder characteristics and post-process curing, could significantly affect the printing quality of the green parts such as geometrical accuracy and part integrity. For powder feedstock with low flowability, even though process parameters could be optimized to partially offset the printing feasibility issue, the qualities of the green parts will be intrinsically limited due to the existence of large internal voids that are inaccessible to the binder. In addition, during the process development, the balanced combination between the saturation level and in-process drying is of critical importance in the quality control of the green parts.
