“…[31][32][33] Biologically inspired mechanical linkage can accomplish complex maneuvers and optimize force and motion, which is very common in bionic UAVs. [34][35][36] Zhang et al [37] designed a single-DOF planar linkage bionic mechanism. The positions of all reference points were continuously constrained by the constraint descent method to meet the requirements of the bionic mechanism in shape, motion trajectory and posture.…”

Raptors are getting more attention from researchers because of their excellent flight abilities. And the excellent wing morphing ability is critical for raptors to achieve high maneuvering flight, which can be a good bionic inspiration for unmanned aerial vehicles design. However, morphing wing motions of Falco peregrinus with multi postures cannot be consulted since such a motion database was nonexistent. The aim of this study was, therefore, to fill this gap in wing morphing kinetics and to provide a reference for future comparative and functional studies. Wing skeleton of the Falco peregrinus was scanned using computed tomography (CT) approach to obtain nine critical postures, followed with motion analysis of each joint and bone. Based on the obtained motion database, a six-bar kinematic model was proposed to regenerate wing motions with a high fidelity.

Nano-attapulgite (ATP) is a layered silicate mineral with abundant reserves, large specific surface area, and low cost. The unique structure of ATP has attracted wide attention in the field of adsorption. In this study, a preparation technology of ATP grafting basalt fiber (BF) was proposed by chemical grafting method based on the idea of plant root bionics. The optimal preparation process of ATP grafting BF was determined through the tests of asphalt absorption performance, thermal stability performance, and segregation dispersion performance. The mechanism of ATP grafting BF was analyzed by micro-morphology, functional group changes, and elemental composition. Finally, the adsorption performance of ATP grafting BF was investigated on the basis of adsorption kinetics model and molecular dynamics simulation. The study results indicated that ATP-BFHCl had better compatibility and wettability with asphalt. The quasi-second-order kinetic equation could better fit the adsorption process of ATP-BFHCl on asphaltene, which indicated that ATP-BFHCl adsorbed asphaltene with chemisorption or ion exchange. The diffusion coefficient and diffusion activation energy of the saturate and the aromatic were larger, indicating a smaller molecular weight and faster movement, and lightweight components of asphalt are more easily adsorbed on the surface of ATP. The diffusion activation energy of asphaltene is the smallest and the reaction is the easiest to take place, which indicates that it is the first to react during temperature increase. The research results can provide a theoretical basis and technical support for BF surface treatment technology.

“…Compared to single DOF 4-bar or 8-bar mechanisms, 6-bar mechanisms can accommodate complex constraints with moderate design difficulty, representing the primary focus of research in this field. In the design process of a 6-bar mechanism, it often involves multiple constraints, including trajectory, shape, and posture constraints [ 40 ]. These factors contribute to the high level of difficulty in designing such mechanisms, and, in some cases, obtaining feasible solutions becomes impossible.…”
