| 1 | Topology optimization of compliant adaptive wing leading edge with composite materials显示文摘An approach for designing the compliant adaptive wing leading edge with composite material is proposed based on the topology optimization. Firstly, an equivalent constitutive relationship of laminated glass fiber reinforced epoxy composite plates has been built based on the symmetric laminated plate theory. Then, an optimization objective function of compliant adaptive wing leading edge was used to minimize the least square error(LSE) between deformed curve and desired aerodynamics shape. After that, the topology structures of wing leading edge of different glass fiber ply-orientations were obtained by using the solid isotropic material with penalization(SIMP) model and sensitivity filtering technique. The desired aerodynamics shape of compliant adaptive wing leading edge was obtained based on the proposed approach. The topology structures of wing leading edge depend on the glass fiber ply-orientation. Finally, the corresponding morphing experiment of compliant wing leading edge with composite materials was implemented, which verified the morphing capability of topology structure and illustrated the feasibility for designing compliant wing leading edge. The present paper lays the basis of ply-orientation optimization for compliant adaptive wing leading edge in unmanned aerial vehicle(UAV) field. | Tong Xinxing Ge Wenjie Sun Chao Liu Xiaoyong | 2014 | Chinese Journal of Aeronautics2014，27，6： | 12 |
| 2 | Integrated design of topology and material for composite morphing trailing edge based compliant mechanism显示文摘The morphing trailing edge based compliant mechanism is a developing technology which can increase lift-drag ratio for variable flight modes by bending down the trailing edge.Composite material design is integrated into topology optimization for the morphing trailing edge based compliant mechanism in the paper.A two-step optimization strategy is established to solve the integrated design problem.Initially,lamination parameters are introduced and viewed as a bridge between structure stiffness and fiber angles for composite material.Design variables include the lamination parameters and element density.The least-squares between actual and desired displacements at output points along trailing edge is adopted to evaluate the deformed capability of the trailing edge.An integrated optimization model for the composite morphing trailing edge is established with the volume constraints.The optimal topologic shape and lamination parameters are initially obtained.Subsequently,a least-squares optimization between fiber angles and the optimal lamination parameters is implemented to obtain optimal fiber angles.Finally,morphing capability of composites trailing edge based compliant mechanism is investigated by simulation and experiments.The results indicate the composites trailing edge based compliant mechanism can approximately bend down 8 degrees and satisfies the design requirement. | Xinxing TONG Wenjie GE Zhenyi YUAN Dajing GAO Xinqin GAO | 2021 | Chinese Journal of Aeronautics2021，34，5： | 2 |
| 3 | Low-dimensional catalysts for oxygen reduction reaction显示文摘Developing highly efficient electrocatalysts to facilitate the sluggish cathodic oxygen reduction reaction(ORR)is a key challenge for high-performance fuel cells.Low-dimensional materials have attracted great attention recently because of their unique structure and properties.In this review,the application of zero-dimensional(0D),one-dimensional(1D),and two-dimensional(2D)materials in ORR are discussed and particular attention is given to the relationship between their structure and the ORR activity.Graphene-based materials,transition metal dichalcogenides,transition metal oxide,nanotubes,nanoribbons,nanowires,and single-atom ORR catalysts are introduced and classified by their geometric dimension. | Xin Tong Xinxing Zhan Diane Rawach Zhangsen Chen Gaixia Zhang Shuhui Sun | 2020 | Progress in Natural Science:Materials International2020，30，6： | 2 |

| 12 | Optimization of the forearm angle for arm wrestling using multi-camera stereo digital image correlation: A preliminary study显示文摘This study analyzes the function of different muscles during arm wrestling and proposes a method to analyze the optimal forearm angle for professional arm wrestlers.We built a professional arm-wrestling platform to measure the shape and deformation of the skin at the biceps brachii of a volunteer in vivo during arm wrestling.We observed the banding phenomenon of arm skin strain during muscle contraction and developed a model to evaluate the moment provided by the biceps brachii.According to this model,the strain field of the area of interest on the skin was measured,and the forearm angles most favorable and unfavorable to the work of the biceps brachii were analyzed.This study demonstrates the considerable potential of applying DIC and its extension method to the in vivo measurement of human skin and facilitates the use of the in vivo measurement of skin deformation in various sports in the future. | Zixiang Tong Xinxing Shao Zhenning Chen Xiaoyuan He | 2021 | Theoretical & Applied Mechanics Letters2021，11，6： | 1 |
| 13 | The effect of evaporator operating parameters on the flow patterns inside horizontal pipes显示文摘A general and simple model for simulating the steady state behaviors of air-to-refrigerant fin-and-tube evaporator is introduced with the focus on the detailed flow patterns inside the tubes.In order to simulate the heat transfer between air and the working fluid,the evaporator is divided into a number of control volumes.Empirical correlations from literature were also adopted to estimate the void fraction,the internal and external heat transfer coefficients,and the pressure drops.Simulations were performed to study the effects of varying inlet air temperature,refrigerant mass flow rate and evaporation pressure on the flow patterns inside the horizontal pipe of the evaporator.The simulation results indicate that the proposed model can be used to predict flow patterns well.The predicted results of the model agree well with experimental results,the difference is within ±3% for the cooling capacity,and is within ±0.2% for refrigerant evaporation temperature. | Lige Tong Haiyan Li Li Wang Xinxing Sun Yunfei Xie | 2011 | Journal of Thermal Science2011，20，4： | 0 |
