Linear guide pairs are the main part of the CNC machine tools. The dynamic behaviours are the main properties of the linear guide. These properties can mainly increase the service life of linear guide pairs. The main propose of this study is the comparison of stiffness of linear guide pairs by fea and experiment. Measure the stiffness experimentally and, compare the results with fea to prove the correctness of fea model. For studying was chosen three linear guides: Chinese company-1, Chinese company-2 and abroad company. The results of this study are (1) Set up the finite element model of linear guides with different geometrical parameters. (2) Comparison of fea and experiment results shows almost same results. (3) The fea results show correctness of analysis. These studies are useful for establishing the stiffness on different structures of linear guides.

A numerical schemes applicable to the direct solution of Boltzmann transport equation (BTE) in vertical-SOI NMOSFET are investigated by means of the finite element analysis (fea).The solution gives the electron distribution function,electrostatic potential,carriers concentration,drift velocity,average energy and drain current by directly solving the BTE and the Poisson equation *** result shows that the direct numerical solution of the BTE with the aid of fea and vertical SOI NMOSFET is a promising approach for ultra short channel transistors modeling.

A new type of Fe-S complex (C), (μ -CH3S) (μ-HOCH2CH2S) Fe2(CO)6which contains μ-β-hydroxyethyl, has been synthesized in high yield through ring-opening reaction of ethylene epoxide under uncleophilic attack of active complex (A), (μ-CH3S)(μ-IMgS) Fe2(CO)6, followed byan alcoholysis of the intermediate (B). The crystal structure of (C)was determined by an X-ray diffraction technique. The crystal belongs to monoclinic system with space group of C2/c. Cell parameters a= 15.784(3), b = 22.172(3), c=9.774(2)A, β=119.53(2)°, V=2976.3A. Dc = *** cm-3 , Z=8, F(000)=1616 and final R=0.077.

Excessive vibration of aircraft wings during flight is harmful and may cause propagation of existing cracks in the material, leading to catastrophic failures as a result of material fatigue. This study investigates the variations of modal characteristics of aircraft wings with respect to changes in the structural configurations. We develop parametric Computer-Aided Design (CAD) models to capture new design intend on the aircraft wing architectures. Subsequent Finite Element Analysis (fea) based vibration analysis is performed to study the effects of architecture changes on the wing’s natural frequencies and mode shapes. It is concluded that the spar placement and the number of ribs have significant influence on the wing’s natural vibration properties. Integrating CAD modelling and fea vibration analysis enables designers to develop alternative wing architectures to implement design requirements in the preliminary design stage.

Fins are the extended surfaces through which heat transfer takes place to keep the surface cool. Fins of various configurations are presently used ranging from automobile engine cooling to cooling of computer parts. Note that in a fin majority of the heat transfer to atmosphere is by convection and therefore in the present research, and importance is given to variation of temperature along the length of the fin which in turn gives rate of heat transfer. In the present research a solid rectangular aluminum fin and the same rectangular fin with different perforations (2, 4, 8 and 10) were compared analytically, experimentally and its validity through finite element analysis for its temperature distribution along the length. From the present research it is observed that the mathematical and fea for a solid rectangular fin without perforations are converging within ±1°C and rectangular fin with 10 perforations are converging within ±2°C and hence the validity.
