VIV (Vortex-induced vibration) of a stay cable subjected to a wind profile is numerically simulated through combining CFD (Computational Fluid Dynamics) code CFX 10.0 and CSD (Computational Structural Dynamics) code ANSYS 10.0. A stay cable with the inclined angle of 30° is used as the numerical model. Under a profile of mean wind speed, unsteady aerodynamic lift coefficients of the cable have been...
P-type multi-crystalline passivated emitter and rear solar cells (PERC) become the focus of recent laboratory and industrial base research due to its promising mass production perspective. This paper presents the most recent works on PERC solar cells and reveals the realization of a world record efficiency of 20.8% PERC solar cell fabricated with screen printing technology on 156 mm × 156 mm multi-crystalline...
In this paper, a novel four-dimensional mixed-order chaotic system is proposed and numerical simulations are first carried out through bifurcation diagrams and Lyapunov exponent spectrum. Based on the fractional-order approximate transfer function, the mixed-order chaotic circuit is designed, and the results of the circuit implementation are given. The existence and physical realizability of the new...
Consider the parametric excitation, studied the characteristics of fifth nonlinear duffing chaotic system. By applying geometric theory of dynamical systems, bifurcation theory and infinitesimal calculus, obtain the homoclinic orbit of fifth duffing equation. Using Melnikov method determines the initial chaotic condition of system and perturbation equation. By means of numerical calculation and computer...
In order to study crack mechanism in stress triaxiality and fracture design of structure steel, the fracture experiments and numerical simulations were performed on 8 Q345 notched bar. Test results showed that crack initiated at the edge of the hole and the minimum section of the notched bars, quickly propagating perpendicular to loading direction. And that had obviously shear fracture trace, the...
