As a result of the inadequate carrying capacity and poor meshing performance gears with few teeth, reasonable optimal choice parameters is key step in design. Aiming at this problem, stress equation for gear pairs teeth was derived it discovered that main failure mode pitting on contacting surface. At same time, results theoretic analysis were also verified by strength test. A new optimization method which aimed minimizing contact presented based equal bending fatigue life tooth root pinion...
Guided waves (GW) are massively used for structural health monitoring and defect evaluation in plate, pipe, rail structures. To accurately efficiently calculate the dispersive natures of GW complex waveguides, this study proposes a novel Gauss–Lobatto–Legendre-based high-order semi-analytical finite element method (GLL-SAFE). Combining GLL node collation Lobatto quadrature into SAFE, mass matrix developed GLL-SAFE is diagonal, which enables faster solution speed reduced error inversion....
Accurate measurement of the material parameters composite in a nondestructive manner is great significance for evaluating mechanical performance. This study proposes to use genetic algorithm (GA) reconstruct stiffness matrix carbon fiber reinforced polymer (CFRP) with array-guided wave (GW)-based GA. By comparing numerically calculated GW dispersion curves experimental number-frequency contour two-dimensional Fourier transform (2D-FFT), matching coefficient directly obtained as objective...
The preforming quality of carbon fiber plain-woven thermoset prepreg (CFPWTP) is critical to the performance composite aerospace parts. deformation ability CFPWTP material during affected by both fabric woven structure and resin viscosity, which different from dry textile material. Incorrect temperature parameters can enlarge resin’s high viscosity inhibit cause defects. This study proposes an equivalent continuum mechanics model considering its temperature–force behavior. Picture frame...
The SCO 2 turbine machines exchange energy through supercritical carbon dioxide. Their impeller has the features of high-temperature and −speed to enhance conversion efficiency, but rotor needs be cooled compatible with bearings seals. paper introduces a pivotal parameter optimization concentrating solar seeks control harmonic response amplitude while preserving distance between critical speed working speed. considers several parameters including bearing span, stiffness, effective mass...
In the design and construction code for gravity quay, inner floor of multi-ribbed buttressed quays generally is divided into two parts to calculate. The part within 1.5 times rib spacing as a three fixed edges one simply-supported slab. restriction effect same. However, because difference in thickness between vertical plate with change direction flow, them not It will lead result deviating. Sometimes, there be phenomenon that maximum bending moment smaller than mid-span moment. Finite...
Laser peening offers potential advantages over conventional peen technologies in terms of the depth residual stresses that can be induced, and improvements surface micro-hardness.The present study was undertaken to understand effect laser penning on properties titanium alloy, a TC4 alloy work-piece processed with ND: YAG wavelength 1064 nm, pulse energy 0-10J width 12ns, micro-hardness stress for different parameters were examined analyzed by tester X-ray diffraction.Results are presented...
Lebus groove can realize multilayer and orderly winding of wire, so it is widely used in hoisting equipment. But these types grooves are difficult to manufacture average lathe. Coping with this situation, the paper developed CNC system based on PMAC. The hardware components, functions, software programming other key technologies introduced article. application result indicates that fully meet requirement manufacturing.
The accurate description of the stress-strain relations rock and soil is very important to analyze its mechanical properties, but forms curves are different. With change confining pressure, it will from softening type hardening or type. Taking one loess as research object, unconfined compressive strength tests undisturbed disturbed consolidated drained triaxial under different pressures carried out. relationship obtained described by composite power exponential model (CPE model).
