The incorporation of a drooping leading-edge wing optimizes the aerodynamic efficiency aircraft under different flight conditions. optimal positioning stringers for cruise condition was determined in this study through optimization equivalent stress fluid–structure coupling. This significantly improved load-carrying capacity leading edge during flight. enhanced suitability four configurations Watt-I six-bar mechanism skeletal structure droop (LD) further evaluated. establishment unified...
Purpose In a dual-robot system, the relative position error is superposition of errors from each mono-robot, resulting in deteriorated coordination accuracy. This study aims to enhance accuracy system through direct compensation errors. To achieve this, novel calibration-driven transfer learning method proposed for prediction systems. Design/methodology/approach A local product exponential (POE) model with minimal parameters modeling. And two-step presented identify both geometric and...
The exceptional energy absorption, deformability, and tuneable Poisson's ratio properties of negative (NPR) honeycomb biomimetic structures make them highly suitable for applications in aerospace, medical, acoustic stealth industries. present study proposes a re-entrant hybrid (REHH) structure comprising octagonal unit cell hexagonal cell. Theoretical models the in-plane elastic modulus are established based on beam theory, these validated through finite element (FE) simulations tensile...
Abstract The layup quality of prepreg fibers onto complex surfaces is the most concerned issue in automated fiber placement (AFP), which intimately related to contact stress tractive rolling contact. An analytical model proposed this paper clarify defects mechanism during AFP process, considers mold curvatures, mechanical properties contacted objects, and pose information make it suitable for irregular arbitrary conditions. Classical Hertz theory expanded 3D area, multi‐scale deformations...
Abstract The primary factors affecting the geometric accuracy of abrasive water jet (AWJ) machining ultra‐thick carbon fiber‐reinforced polymer (CFRP) laminates are cutting front drag and kerf width deviation caused by energy dissipation. Firstly, this study comprehensively analyzes influence coupling relationship between on hole machining. Secondly, a gradient distribution theory for traverse speed with depth is proposed taper characteristics. Finally, general error model applicable to both...
