PROJECTS

Meshing on Side door, Back door, & Batch Meshing on Hood in Hypermesh, Skill-Lync

In all three models, unwanted edges were suppressed and certain geometry cleanup operations were performed.

Mid surface was extracted since the thickness of the given model was less than 6mm.

Finally, mesh was generated with proper mesh flow with thickness assigned along with element quality check.

Frontal crash analysis of a Dodge Neon BIW model using Hypermesh and Radioss, Skill-Lync

Created interface, rigid wall/pillar, kinematic conditions, output requests.

Understood how to rectify and fix errors via model checker and penetration check.

Analyzed the result by using the graph generated from HyperGraph.

Side Crash Analysis of a Dodge Neon BIW model using Hypermesh and Radioss, Skill-Lync

Checked and created the interface properties for a side crash, created interface & rigid pillar.

Requested output request for sectional forces & intrusions in pillars and peak velocity of inner panel node of the door.

Analyzed the result by using the animation file in HyperView & graphs in HyperGraph.

Roof Crush analysis of a Dodge Neon BIW model using Hypermesh and Radioss, Skill-Lync

Created interface between the impactor and the car, applied required boundary conditions and gravity to the model.

Imposed displacement was given to the impactor model, created engine card and included animation files.

Plotted energy vs. time curves and analyzed the results using HyperGraph and HyperView.

Grid dependency test on a Bevel gear using ANSYS, Skill-Lync

Grid dependency test helps in determining optimal mesh size where the accurate result could be obtained.

4mm, 5mm and 6mm mesh size were used to carry out the static structural analysis.

Post processing results conclude that smaller the mesh size, higher is the accuracy of results.

Simulation of frontal impact car crash using ANSYS, Skill-Lync

A frontal impact car crash simulation in Explicit dynamic analysis was performed.

Also a parametric study is done for three different thicknesses of the car body such as 0.2mm, 0.4mm and 0.6mm

Results conclude that greater the thickness of the car body, higher is the stress and lesser is the deformation.

Topology Optimization for light weight design of Brake pedal arm using ANSYS, Skill-Lync

Brake pedal arm model is initially carried out with a static structural system for a certain set of constraints and loads..

The model is then optimized for areas of minimally developed stress.

The excessive weight is cut and an optimized design is carried over which meets 50% material retain criteria.

Meshing of Dashboard and Door CAD models of a car using ANSA, Skill-Lync

Performed model cleanup using auto cleanup and manual tools

Extracted mid surface manually and stitched using different tools.

Created mesh with the required quality criteria.

Meshing and Connections of Cross Car Beam (CCB) using ANSA, Skill-Lync

Performed model cleanup and extracted mid surface manually and edges are stitched using different tools.

Created mesh with the required quality criteria.

Performed all different types of connection RBE2, RBE3, Seam weld, Adhesive using Nastran Deck.

Meshing of a Suspension assembly of a car using ANSA, Skill-Lync

Performed geometry clean-up removed Triple cons, Single cons as per requirement.

Performed 2D and 3D meshing according to the component suitability and later connections on FEA model .

Eliminated errors from the elements like opposite trias, rotating quads, skewness, warping,etc as per quality criteria provided.

Pedestrian Head impact simulation using LS-DYNA, Skill-Lync

Performed head impact simulation on a Pedestrian head-foam model impacting against a rigid wall and a hood of a car.

Suitable initial velocity and boundary condition were imposed on the model

HIC factor is calculated to determine the level of damage imparted onto the head region.

Verification and Validation of Material modeling from test data using LS-DYNA, Skill-Lync

Modeling Elasto-Plastic and Hyper-elastic material models for a uni-axial test data provided.

Using a Dog-bone specimen, verified the test data and obtained the material constants from d3hsp file.

Validated the simulation data with actual data for the created material models.

Bird-strike analysis on an Aircraft Engine and Windshield using LS-DYNA, Skill-Lync

Developed a numerical methodology to examine the damages and failure of an aero-engine and to estimate the windshield structure capability to absorb the impact energy due to bird-strike.

Created suitable contacts, material assignments, applied initial velocity conditions for both the simulations.

Using binary plot files, energy distribution graphs and failed blade elements have been analyzed.
