Professional experience

CAE Engineer April 2017 – Present

DEP India Pvt Ltd, Chennai

4 years of Experience in Computer Aided Engineering (CAE), able to work in almost all aspects of modeling and Finite Element Analysis (FEA) of Mechanical Components analysis

Good ability and experience in performing Structural simulation, linear and non-linear, complex contact FEA in Assembly level, Stiffness analysis and engineering calculations.

Experience in Optimization, Analyzing and directing recommendations for problem resolution/design improvement in support of the CAD team. Project executed:

1. Front door strength analysis for various loading condition Description

Finite Element modeling of Door inner panel, Hinges, Doors hinge reinforcement, reinforcement mirror mountings, Front door skins, Door latch reinforcement, Upper beam, lower beam front door parts are done.

Different types of connections are used to connect different front door parts.

Various loading conditions are performed to evaluate door sagging, Static stiffness and dent resistance.

With specified Boundary conditions and loading conditions were defined.

Specified loading points were defined with sets, and output results are validated to check the stiffness in local regions. Displacement, Stress and strain results are validated with given values.

The results were post processed and validated with existing proposed results. Software used: Hypermesh, Abaqus, Hyperview

Client: LMC Pvt Ltd

2. Full vehicle BIW global stiffness analysis

Description:

Full vehicle model building was ensured with required quality guidelines and FE checks as well.

Connections were created by using spot welds, adhesives and rigid with the specified connector data.

Model analysis is carried out to ensure the connectivity of the full BIW vehicle.

Global frequency values are validated with the other frequency to avoid resonance.

The required loads and boundary conditions are applied to carry out the bending and torsional stiffness analysis.

The result values are validated to pass the required target results and the design changes were proposed in the weaker areas.

Software used: Hypermesh, Ansa, Abaqus, Hyperview

3. Strength analysis of Rear axle assembly for the various load conditions Description:

Finite element modeling of Axle carrier, bearing cap, leaf brackets was represented using tetrahedral element and brackets, Axle tube and cover plate were represented by Hexa element.

Bolts are represented by hex element. Sets are created at the weld HAZ region.

Contact nonlinear analysis with given load cases were accomplished.

The results were post processed and validated with existing proposed results.

Counter measures were suggested for design changes. Software used: Hypermesh, Abaqus, Hyperview and Meshwork Client: FCA Group Pvt Ltd

4. EV Battery frame design optimization for gravity loadings Description:

Finite Element modeling were created for Front frame, rectangular channel frame, square channel frames, supporting plates, V-brackets, L-brackets and C-brackets

Basic necessary checks are carried out and all sheet metal parts connected with various connections likely RBE2, RBE3 and seam welds to connect the parts.

The bolts are connected with RBE2 and beam elements. Gravity load and boundary conditions are defined to check the frame strength.

Design parameters were created to reduce the stresses in brackets and frames component.

And DOE were created and no. of design samples were solved using I-sight software and better combination was found.

Results were post processed and Design changes are proposed in frames for better performance. Software used: Hypermesh, Nastran and Hyperview

Projects Executed at GMTCI Bangalore (June2017-Feb2018) 5. FE modeling of Front Fascia, Rear Fascia, Head lamp and IP Structured Assembly Description:

Finite element modelling of Plastic components of fascia assembly. Quality parameters and setting up of Material/Property according to client's requirements.All the standard FEM checks were ensured.
