Large-scale synthesis of recyclable photocatalysts for pollutant degradation remains a challenge. Epitaxial growth powdered on substrates is constrained by the dedicated materials with highly matched lattices and...
The surrogate-based optimization of hierarchical stiffened composite shells against buckling is a typical multimodal and multivariables problem. To improve the computational efficiency global optimizing ability shells, an enhanced variance reduction method based on Latinized partially stratified sampling multifidelity analysis methods proposed in this paper then integrated into framework. In offline step framework, candidate pairing strategies design variables are generated by compared...
Abstract Due to manufacturing error and wear, the profiles of bushing pin in revolute clearance joints are usually non-circular, while traditional kinematic models for generally assume a circular profile or bushing, which may not be able accurately capture behavior real multibody systems. To this end, curvature center method was proposed modeling with noncircular pin. In method, both were discretized, radius corresponding each discrete point then obtained detect contact between based on...
Titanium alloys have been widely used in aerospace and manufacturing industry because of their unique high strength-weight ratio, fracture resistance, superior resistance to corrosion. In this paper, a series experiments were carried out research the surface integrity grinding alloy TC11 on milling centre with small vitrified bond CBN wheel. Nine runs involved orthogonal array are designed accordance three factors at levels. The roughness Ra 0.72 um Rz 4.73 obtained. Subsequently ANOVA is...
Abrasive medium plays an important role in the application of abrasive flow machining (AFM), a process that finishes complex internal and external geometries. A new needs to be fabricated due lack literature on it. In this work, was by using styrene butadiene rubber (SBR) as carrier DF-101S used study its characterization. Results showed with good fluidity temperature stability obtained. Processing experiments have also been carried out MLLD60, ZYGO surface characteristics work-piece....
The air compressing efficiency and heat conductance of aero-engine is markedly influenced by the surface micro-morphology roughness impeller blades, which will further affect thrust weight ratio plane. To achieve low flow losses, values blade must be below certain limits. Some polishing techniques as final finishing process blades are reviewed their recent developments shown in paper. Further more a new kind point-by-point NC principle for surface, gradually change from inlet to outlet, presented.
Optimal fixture involves layout and clamping force determination. It is critical to ensure the machining accuracy of workpiece. In this paper, process analyzed with consideration cutting forces frictions using finite element method. Then are optimized by minimizing workpiece deformation via a Genetic Algorithm (GA). Subsequently, linear programming method used estimate stability shown through an example that proposed proved be efficient. The optimization result not only far superior...
Superhydrophobic surfaces on aluminum, stainless steel, titanium alloy, and copper substrates were fabricated by nanosecond laser etching fluoroalkylsilane modification. Compared with the existing beam machining technologies, such as femtosecond picosecond etching, for fabricating superhydrophobic surface, method developed us is inexpensive high efficiency. The influence of parameters surface morphology wettability studied through orthogonal analysis method. good superhydrophobicity contact...
In this study, a finite‐element simulation model was established for two‐dimensional hydraulic cylinder seal structure with highly nonlinear materials and contacts achieving the optimal sealing effect structure. The effects of gaps as well single double O‐rings on were examined. On basis examination, parametric developed double‐O‐rings without gaps, which are suitable sealing. Suitable design variables, objective functions, constraint conditions determined model. Then, surrogate fitted...

The collected can be not only save in gateway's embedded database,but also transferred the long-distance server.Which solve farmland monitoring storage, distribution mobile measurement inconvenience issues. Solar power supply module has...
In this paper, we study a new type of circle packings in hyperbolic background geometry. Horocycles and hypercycles are also considered packing. We give the existence rigidity packing with conical singularities terms total geodesic curvature. Moreover, introduce combinatorial curvature flow on surfaces to find desired prescribed
This paper investigates a generalized hyperbolic circle packing (including circles, horocycles or hypercycles) with respect to the total geodesic curvatures on surface boundary. We mainly focus existence and rigidity of whose contact graph is $1$-skeleton finite polygonal cellular decomposition, which analogous construction Bobenko Springborn [4]. Motivated by Colin de Verdi\`ere's method [6], we introduce variational principle for packings polygons. By analyzing limit behaviours polygons,...
