Free vibration and axial compression of all-metallic cylindrical and truncated conical sandwich shells with corrugated cores

Journal of Sandwich Structures & Materials (2020)

Mao Yang Bin Han Pengbo Su Zihan Wei Qi Zhang

All-metallic sandwich-walled cylindrical and conical structures for aerospace applications often require simultaneous excellent vibration and load-carrying capacities. In the present study, the free vibration and axial compression behaviors of cylindrical and truncated conical sandwich shells with corrugated cores are investigated using a combined experimental and numerical approach. Excellent agreement between experimental measurements and finite element simulations for representative vibration and axial compression characteristics is achieved. Parametric studies based on the response surface model are subsequently performed to quantify the influence of key geometrical parameters on vibration and axial compression performance. A multi-functional collaborative design to meet the requirement of high load-bearing capacity subjected to the constraint of low natural frequency is also carried out, which demonstrates the unique advantages of the novel sandwich-walled shells for aeronautical and astronautical applications.

Nanoscale Au-ZnO Heterostructure Developed by Atomic Layer Deposition Towards Amperometric H2O2 Detection

Nanoscale Research Letters (2020)

Hongyan Xu Zihan Wei Francis Verpoort Jie Hu Serge Zhuiykov

Abstract Nanoscale Au-ZnO heterostructures were fabricated on 4-in. SiO 2 /Si wafers by the atomic layer deposition (ALD) technique. Developed Au-ZnO heterostructures after post-deposition annealing at 250 °C were tested for amperometric hydrogen peroxide (H 2 O 2 ) detection. The surface morphology and nanostructure of Au-ZnO heterostructures were examined by field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), etc. Additionally, the electrochemical behavior of Au-ZnO heterostructures towards H 2 O 2 sensing under various conditions is assessed by chronoamperometry and electrochemical impedance spectroscopy (EIS). The results showed that ALD-fabricated Au-ZnO heterostructures exhibited one of the highest sensitivities of 0.53 μA μM −1 cm −2 , the widest linear H 2 O 2 detection range of 1.0 μM–120 mM, a low limit of detection (LOD) of 0.78 μM, excellent selectivity under the normal operation conditions, and great long-term stability. Utilization of the ALD deposition method opens up a unique opportunity for the improvement of the various capabilities of the devices based on Au-ZnO heterostructures for amperometric detection of different chemicals.

Bending Response of 3D-Printed Titanium Alloy Sandwich Panels with Corrugated Channel Cores

Materials (2021)

Zhenyu Zhao Jianwei Ren Shaofeng Du Xin Wang Zihan Wei

Ultralight sandwich constructions with corrugated channel cores (i.e., periodic fluid-through wavy passages) are envisioned to possess multifunctional attributes: simultaneous load-carrying and heat dissipation via active cooling. Titanium alloy (Ti-6Al-4V) corrugated-channel-cored sandwich panels (3CSPs) with thin face sheets and core webs were fabricated via the technique of selective laser melting (SLM) for enhanced shear resistance relative to other fabrication processes such as vacuum brazing. Four-point bending responses of as-fabricated 3CSP specimens, including bending resistance and initial collapse modes, were experimentally measured. The bending characteristics of the 3CSP structure were further explored using a combined approach of analytical modeling and numerical simulation based on the method of finite elements (FE). Both the analytical and numerical predictions were validated against experimental measurements. Collapse mechanism maps of the 3CSP structure were subsequently constructed using the analytical model, with four collapse modes considered (face-sheet yielding, face-sheet buckling, core yielding, and core buckling), which were used to evaluate how its structural geometry affects its collapse initiation mode.

Axial compressive collapse of ultralight corrugated sandwich cylindrical shells

Materials & Design (2018)

Pengbo Su Bin Han Mao Yang Zihan Wei Zhenyu Zhao

Ultralight all-metallic sandwich cylindrical shells with corrugated cores are designed and fabricated using a method involving tamping and shape correction. Quasi-static axial compressive behaviors of the sandwich shells are investigated using a combined experimental, theoretical and numerical approach. Based on the analytical model and numerical approach, systematic parametric study is carried out to explore the effects of key geometrical parameters on the failure load and energy absorption capacity. Minimum weight design as a function of the failure load is subsequently carried out for the proposed sandwich shell. As an attempt for further performance enhancement, the foam-filled corrugated-core sandwich cylindrical shell is proposed and a preliminary experimental study is carried out. The superiority of sandwich shells over monolithic shells in terms of initial failure load and energy absorption is clearly demonstrated, potentially important for applications demanding simultaneous ultra-lightweight, load-bearing and energy absorption.

Thermal Stress Analysis of DC Dry Type Wall Bushing

2022 IEEE 6th Advanced Information Technology, Electronic and Automation Control Conference (IAEAC ) (2021)

Yongqiang Wang Sen Fang Zihan Wei Xiaolei Zhang

As the connection equipment between the valve hall of the converter station and the external transmission network, the DC dry type wall bushing has a big difference in ambient temperature on both sides of the wall, and the distribution of internal heat and thermal stress is complex. This paper adopts three-dimensional temperature-fluid-stress coupling calculation method. The geometric model was built according to the actual size of ±110kV DC dry type wall bushing. The temperature field and thermal stress distribution of the DC dry bushing under the environment temperature difference are calculated by simulating the fastening constraint condition of the bushing with full consideration of bushing loss and heat dissipation mode, and the validity and accuracy of the calculation results are analyzed. The research results in this paper can provide a theoretical basis for the design and optimization of the structure of the DC dry type wall bushing.
