Design and Analysis of the Driving Mechanism of Multi-DOF Flapping Wing Aircrafts

Jixie chuandong, 2022
In order to improve the flight performance of flapping wing aircrafts，a multi-DOF flapping wing mechanism based on space four-bar mechanism is designed by referring to the flight motion characteristics of small and medium-sized birds. Firstly，a kinematic

Kinematic fingerprint of core-collapsed globular clusters

, 2018
Dynamical evolution drives globular clusters toward core collapse, which strongly shapes their internal properties. Diagnostics of core collapse have so far been based on photometry only, namely on the study of the concentration of the density profiles ...

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

BELT TENSION ANALYSIS AND KINEMATIC CALCULATION

, 2022
Annotation: when we analyze these graphs, the number of transmissions is greater than the largest, The number of transmissions reaches the smallest value. So, from the graph it turns out that with the growth of the eccentricity of the tensile roller, the change in the number of transmissions of the stretch occurs as the interval increases in one ...

Influence of an Oxygen‐Free Atmosphere on Diamond‐Single‐Grain Scratching of Ti–6Al–4V

Advanced Engineering Materials, EarlyView.
Single‐grain scratching of Ti–6Al–4V is investigated under controlled, oxygen‐free, and ambient atmospheres using a novel experimental setup with in situ high‐speed imaging. The approach enables direct observation of chip formation and adhesion under suppressed oxidation.

Hyperspherical partial wave theory applied to electron hydrogen-atom ionization calculation for equal energy sharing kinematics [PDF]

, 2002
Hyperspherical partial wave theory has been applied here in a new way in the calculation of the triple differential cross sections for the ionization of hydrogen atoms by electron impact at low energies for various equal-energy-sharing kinematic ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Traction Calculation for Modular Energotechnological Unit Given Kinematic Mismatch of Driving Axles

Сельскохозяйственные машины и технологии, 2022
The power of the engine of energy-saturated tractors often proves not to be fully used. One of the solutions to this problem might be the use of the unit technological part as an active coupling weight.
