Professional Experience:

EDS Technologies : NOV-2010 - Till date

Designation : CAE Engineer

Education Qualification:

M.Tech in CAD/CAM/CAE with Distinction, from J.N.T.University.

Projects Held:

1. Title : FE Modeling of Various Power Train Assembly components.

Nov 12- Till

Role : CAE Engineer

Tool Used : Hypermesh,Ansys.

Description: The main objective of the project was to create FE model for

analysis of Power train components like exhaust manifold, motor casing,

Cylinder Head Casing etc. After geometry cleanup Penetration and

Intersections were removed in the entire model and 2D elements were meshed

and thus strict quality was maintained. Thereafter vibration analysis is

carried and found out the natural frequencies for the motor casing.

2.Title :FEM modeling of Car assembly for ROLLS - ROYCE

Jul-12 to oct-12

Role : CAE Engineer

Tool used : HyperMesh, Nastran.

Description : The Project involved FE modeling of BIW Components with

shell elements. Since the components are of uniform thickness, one side

surface of the component and thickness are given. To get the shell elements

on the midsurface the given surfaces are offset by the value of half the

thickness in a given direction and modeled with an element size of 10mm for

NASTRAN profile with given quality criteria.

3. Title: Linear & Non-Linear Static Analysis For Strength and System

Fatigue of Chassis components

Role : CAE Engineer

Jan-12to Jun-12

Tool used : Hypermesh,Ansys.

Description: The chassis components were meshed with tetra elements. The

strength and the fatigue life of the chassis components are very important

for the manufacturer. A Non-linear static analysis is performed to

determine its static strength, as well as a liner static analysis is

performed to determine the stress responsible for the fatigue failure. Sub-

modeling has done at required section. Stress-strains and displacement

results are plotted.

4.Title : FE Modeling of Aerospace Components for ROLLS-ROYCE

Aug-11 to Dec-11

Role : CAE Engineer

Tool used: Hypermesh, Ansys.

Description: Here BR710 engine, wide-chord single-stage direct-drive fan

modeling was done with shell elements using Hyper mesh. Initially all

components were extracted and modeled with quality parameters, and also

checks for edges and Normals. Assigning thickness to the elements and card

image for that. And ensured that flow is maintained and capturing features.

Static and Modal analysis has done and find out the natural frequencies

and mode shapes of the body.

5 Title : Modeling of Plastic Components

Mar-11 to Jun-11

Role : CAE Engineer

Tool used : Hypermesh

Description : Here the modeling was done with shell elements using

Hyper mesh. Initially all components were extracted and modeled with

quality parameters like war page, aspect ratio, minimum & maximum angle of

quads & trias, skew & jacobian as per the project Quality Parameters, and

also checks for edges and normal's. Assigning thickness to the elements and

card image for that.

Many Finite element models were developed for various panels such as

Parts of Console, Door, HVAC parts, Speaker grill, Switch bezel, Parts of

Air bag, Upper Cross beam, Hood (it consists of inner panel and outer

panel), dash Panel, front quarter panel, Floor Panel.etc.

Roles & Responsibilities:

V Performing Geometric cleanup for BIW and Plastic components before

suspension, chassis frame, wheel and steering etc and linear and non-

linear analysis is done.

V Sub-modeling for the specified location from entire assembly.

V Checking interacting surfaces for contact set for any malfunction.

V Creation of FE models and FE analysis of Geometric models provided by

customer.

V Review the results and check for any unexpected behavior stresses in

the model.

V In order to avoid resonance and reduce noise, modal analysis is done

to obtain natural frequencies and mode shapes for automobile & aero

components.

V Providing the best quality output to the Analysis team for their

further process.

V Analysis is done to determine the dynamic behavior of the vehicle in

Harmonic and Transient excitations.

V Interact With Customer To Understand the Requirements.

Personal Skills:
