Here the theoretical maximum contact stress is calculated by Hertz equation. Also the finite element analysis of spur gear is done to determine the maximum contact stress by ANSYS 14.5. It was found that the results from both Hertz equation and Finite Element Analysis are comparable. From the deformation pattern of steel and grey cast iron, it could be concluded that difference between the maxi...

This research aims to simulate a gravity flow fractionation—the process to fractionate erythrocytes through gravitational field using ANSYS simulation software. A particular microfluidic channel was designed as a separation device. The gravitational equilibrium conditions of the erythrocytes and gravitational field as the parameters were chosen, then deriving the erythrocytes’ path through nume...

Recently new threats to humans are observed from electromagnetic radiation from various sources like mobile phones, transmission lines and many more. For providing continuous and uninterrupted supply of electric power to consumer’s maintenance operation of high voltage power lines are often performed with systems energized or live. This is referred as Hot Line maintenance or live line maintenan...

The active magnetic bearing (AMB) is an integral part of the industrial rotational machine. The paper deals with simulation study of three and four coil AMB utilizing Finite Element Method (FEM). This paper also presents how ANSYS software (Ver. 12.1) can be used to perform the magnetic field analysis in the AMB. This work reports ANSYS simulation for two different structure of AMB that uses th...

A four-leaf steel spring used in the rear suspension system of light vehicles is analyzed using ANSYS V5.4 software. The finite element results showing stresses and deflections verified the existing analytical and experimental solutions. Using the results of the steel leaf spring, a composite one made from fiberglass with epoxy resin is designed and optimized using ANSYS. Main consideration is ...

Dynamic excitation of any machine tool structure is based on natural frequency of the structure and corresponding mode shape. Initial work of the thesis presents a systematic procedure and details of the use of experimental analysis and finite element modal analysis technique for determining the structural dynamic response of end milling machine.The simplified experimental modal analysis of dif...

This Master’s Thesis compares two computational fluid dynamics solvers: the commercial solver ANSYS CFX and the open source code OpenFOAM. Simple benchmark cases with compressible and incompressible flows are tested and compared. Thereafter the more complex process of quenching in coal gasification is simulated. This thesis work describes the simulation of a part of the coal gasification proces...

-In the present work an attempt is made to evaluate the suitability of composite material such as E-Glass/Epoxy and HMCarbon/Epoxy for the purpose of automotive transmission applications. A one-piece composite drive shaft for automobile is designed and analyzed using ANSYS software respectively for E-Glass/ Epoxy and HM-Carbon/Epoxy composites with the objective of minimization of weight of the...

−− A numerical model was developed to study heat transfer process during freezing of biological tumors. Two different cryosurgical systems, Endocare cryoprobe and novel combined cryosurgery and hyperthermia system, were investigated using the multidimensional, finite element method (FED) developed in Ansys (V7.0) by us recently. The tissues were modeled as nonideal materials, the thermophysical...

The fluid/structure interaction (FSI) investigations of stacked chip in encapsulation process of moulded underfill packaging using the two-way Coupling method with ANSYS Fluent and ANSYS Structural solvers are presented. The FSI study is executed with different aspect ratio of stacked chip on the mould filling during the encapsulation process. The simulation results in the FSI study is well val...
