BISWAJIT CHAKRAVARTY

FEA analyst with 7.5 years of expertise in product development and structural simulation in automotive, aerospace, agri-machinery, and heavy-duty construction equipment. Specialized in HyperMesh, SimLab, Nastran, OptiStruct, and Abaqus, performing static, dynamic, and modal analyses to pinpoint stress hotspots and propose design optimizations. Pursuing a leadership role to enhance engineering projects through advanced finite element analysis.

Structural Analysis of Battery Support Bracket Assembly

• Evaluated a redesigned battery support bracket assembly for the FT12+3 SPB 4WD tractor to verify structural strength.
• Performed pre-processing in HyperMesh per CAE guidelines and post-processing in HyperView to identify stress hotspots on the battery tray.
• Observed stresses exceeding acceptable limits in the area of concern and conducted multiple design iterations to resolve high-stress zones.

Stress Analysis of a Combine Harvester

• Conducted root-cause analysis of field failures on Indian mid-range combine harvesters and recommended design changes.
• Performed 2D/3D meshing with connections for full vehicle integration as per drawing and free-free modal analysis to verify assembly connectivity.
• Ran stress analysis to replicate field failures, iterated on design modifications, and documented results for successful field deployment.

FE Modelling of Door Trim Sub-Assembly

• Built a flow-through FE mesh model of a car door trim sub-assembly in HyperMesh to support crash analysis, from IGES geometry import through solver-ready export.
• Performed geometry cleanup and feature identification (bolts, holes, beads).
• Created midsurfaces for 2D shell meshing, including dog-house components. Generated washer mesh around holes/cutouts and assembled components using RBAR, RBE2, BOLT, and SPOT connectors.
• Ran modal analysis in OptiStruct and reviewed results in HyperView.

Optimization and Validation of Front Axle Support (VAVE)

• Selected the front axle support assembly for mass optimization based on design study findings.
• Performed FE modeling per CAE guidelines, applied loads/boundary conditions, and defined the design space for optimization.
• Achieved a 15% mass reduction with minimum weight as the optimization objective; validated results against performance targets.
