A simple mathematical model of an indirect-fired strip annealing furnace for real-time control and optimization purposes is developed. The considered furnace is part of a hot-dip galvanizing line and is used for continuous heat treatment of steel strips. The heat that is released during the combustion process inside the radiant tubes is calculated by means of steady-state mass and enthalpy bala...
this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...
In Meshless natura1 neighbour Petrov-Galerkin method, The natural neighbour interpolation is used as trial function and a weak form over the local polygonal sub-domains constructed by Delaunay triangular is used to obtain the discretized system of equilibrium equations, and it’s a new truly meshless method. This method simplified the formation of the equilibrium equations, facilitates the impos...
Infinitesimal deformations of a homogeneous and isotropic thick elastic plate have been analyzed by using a meshless local Petrov– Galerkin (MLPG) method and a higher-order shear and normal deformable plate theory (HONSDPT). Radial basis functions (RBF) are employed for constructing trial solutions, while a spline function is used as the weight function over a local subdomain. The present metho...
-The propagation characteristics of the surface acoustic waves (SAW) propagating under the periodic metal grating on ST-cut quartz substrates were theoretically investigated in order to achieve more accurate design of the devices. The theoretical method used here is based on Floquet’s theorem using the space harmonics method (SHM) as an orthogonal function set. The boundary conditions are satis...
The presence of right half plane (RHP) zeros in the transfer function relating the base torque to the tip position has long been the source of diiculty in noncollocated control of a Single Flexible Link (SFL). In this paper, we suggest an alternative noncollocated measurement called the virtual angle of rotation. We then show the following. a) The tranfer function with this output does not have...
In some of the engineering problems, it is necessary to analyze the three-dimensional temperature profiles. In order to solve a typical problem numerically, the three-dimensional temperature diffusion equation is chosen as the mathematical model. The finite volume formulation is derived using Galerkin approach for the mesh of tetrahedral elements, which facilitates solving temperature problems ...
