Manager

Maruti Suzuki India Limited

Handling a team of two well-qualified engineers.
Discussion of loads, boundary conditions, and technical review for team members with the design team.
Structural analysis of power train systems and subsystems.
NVH analysis of Powertrain Modal & FRF analysis components, mainly transmission system.
Multibody dynamics MBD analysis of power train system.
Establishing NVH correlation between CAE and test results.

Projects :
(1) Durability analysis of passenger car transmission housing under input and impact torque conditions.
(2) Modal, FRF modal, and direct and MBD analysis of full power train. to provide a solution for gear rattle noise issue resolution and to check rigidity of the powertrain.
(3) Developed the gear shifting lever knob assembly impact analysis process as per testing procedure using Altair Radioss software.
(4) Sound Pressure level calculation for transmission housing as per bench condition for noise measurement.
(5) Frequency response and modal participation factor of engine assembly.
(6) Developed the Valvetrain screw failure resolution process using Adams flex body MBD analysis.
(7) The rubbing noise problem of the clutch release bearing and clutch Guide pipe is resolved by Dynamic Simulation in Adams.
(8) Clutch mounting bracket strength and fatigue analysis and correlation with physical testing. Establish the standard analysis procedure for the clutch mounting bracket.
(9) Modal CAE tests correlation of transmission housing frequency and mode shapes to correlate the CAE and test result for validation of the FE model.
(10) Clutch thermal analysis under sequential load and unloading, to provide a solution to the clutch burning issue.

September 2014 - March 2016

Manager

Escorts Agri Machinery Limited

I was handling a team of three well-qualified engineers.
Durability & Fatigue analysis: Linear stress, Non-linear stress, Dynamic stress & Fatigue Life Analysis.
Individual responsibility for CAE analysis of the New Escorts tractor series NETS project.
NVH analysis Modal, FRF, SWL, Transmission Loss analysis of muffler of tractor components.
Conduct technical reviews with the design team to improve the design of the tractor components.

Projects :
(1) Tractor full chassis structural analysis under service load condition.
(2) Tractor Hydraulic assembly: Establish the analysis procedure for hydraulic assembly for tractors.
(3) Roll Over Protection Test ROPS for tractor cabin analysis is carried out as per ISO to check the cabin structure penetration into deflection limiting volume. (4) Transmission loss calculation of tractor muffler using LMS Virtual Lab.
(5) Transient FRF analysis is carried out for tractor muffler, radiator assembly, LSV-407, and tractor mirror assembly based on measured data.
(6) Resolving the field failure issue of FARMTRAC 60 stay bar mounting bracket by optimizing the design using optistruct topology optimization which leads to, a highly improved design from a strength point of view and also savings of 4kg per tractor.
(7) Filed failure co-relation of the hydraulic body of tractor with close co-relation of CAE results and actual failure location.
