| 1 | A Neural-network-based Approach to Study the Energy-optimal Hovering Wing Kinematics of a Bionic Hawkmoth Model显示文摘This paper presents the application of an artificial neural network to develop an approach to determine and study the energy-optimal wing kinematics of a hovering bionic hawkmoth model.A three-layered artificial neural network is used for the rapid prediction of the unsteady aerodynamic force acting on the wings and the required power.When this artificial network is integrated into genetic and simplex algorithms,the running time of the optimization process is reduced considerably.The validity of this new approach is confirmed in a comparison with a conventional method using an aerodynamic model based on an extended unsteady vortex-lattice method for a sinu soidal wing kinematics problem.When studying the obtained results,it is found that actual hawkmoths do not hover under an energy-optimal condition.Instead,by tilting the stroke plane and lowering the wing positions,they can compromise and expend some energy to enhance their maneuverability and the stability of their flight. | Anh Tuan Nguyen Ngoc Doan Tran Thanh Trung Vu Thanh Dong Pham Quoc Tru Vu Jae-Hung Han | 2019 | Journal of Bionic Engineering2019，16，5： | 2 |
| 2 | Influence of Process Factors on Electrode Wear Rate when EDM 90CrSi Steel using Graphite Electrodes显示文摘The findings of a study on the optimization of Electric Discharge Machining(EDM)procedure for processing cylindrically shaped components with graphite electrodes are presented in this paper.Tool steel 90CrSi was the material of choice for the study’s workpiece.Additionally,the Electrode Wear Rate(EWR)was chosen as the optimization problem’s objective function.An experiment using the Taguchi design was conducted to address this issue.Additionally,experiments were created and their outcomes were analyzed using the Minitab R19 program.The impact of the input process factors on EWR was investigated,including the powder concentration,the pulse on and off times,the servo current,and the servo voltage.Additionally,the best process variables for a minimal EWR were provided. | Tran Huu Danh Le Thi Phuong Thao Nguyen Thi Quoc Dung Vu Trung Tuyen Luu Anh Tung | 2023 | Journal of Environmental Science and Engineering(B)2023，12，5： | 0 |
