Stereoscopic Warehouse plays an important role in the modernization of the logistics field. It is characterized by an informatization, automation, high efficiency, and often used in regional distribution center. In some special occasions or due to special field, the stereoscopic warehouse must be with tandem storage space in the reason that putting all of the racks parallelly in a single storage requires...
We present a mesh less method for local deformation and crack simulation of plastic thin shell. Although previous mesh less methods have done the similar simulations, there exists a problem that the moment matrix may be singular. And the result is that the shape function cannot be constructed to finish the simulation. Special work is needed to deal with the problem. In this paper, we propose a mesh...
The natural zeolite was investigated as an inexpensive and effective adsorbent for the adsorption of Amido Black 10B, Acid Red and Safranine T from its queous solution respectively. The effect of parameters such as the solution of pH, contact time, the doze of the natural zeolite and the initial concentration of dye was examined. The adsorption isotherm was well fitted to both the Langmuir and Freundlich...
A simulation research concerning the gap flow performance of multi-pad hydrostatic thrust bearing having circular cavities in the large-scale vertical CNC lathe was described. The Finite Volume Method of Fluent has been used to compute fluid three-dimensional velocity field and pressure field of gap flow between the revolution working table and bearing pad. This study theoretically analyzes the influence...
A theoretical comparative study concerning performance of a constant flow hydrostatic thrust bearing having multi-circular recess and sector recess is described. The Computational Fluid Dynamics and the Finite Volume Method have been used to compute the characteristics of a constant fluid hydrostatic thrust bearing with circular and sector recesses. The performance has been compared, namely, recess...
A high-order PE method has been derived and analyzed for solving multi-object RCS for the first time. Compared with the existing method SPE, the present method has following features: Firstly, boundary conditions including PML and scatterers boundary conditions can be handled as easy as SPE method. Secondly, to obtain the full bistatic RCS, we need only two rotated PE runs for high-order PE while...
Classical finite-difference time-domain (FDTD) method has been widely used in computational electromagnetics, but for electrically large domains and for late-time analysis, FDTD method begins to show its limitations due to the accumulation of phase errors. To solve this problem, several methods have been proposed such as high-order schemes and four-stage Runge-Kutta integrator. Recently, the symplectic...
