Project 1: DESIGNING A ROBUST GEARBOX WITH FIXED FORM FACTORS AND ARCHITECTURE FOR A WIDE RANGE OF TORQUES - Designed Gearbox using robust design methods against conflicting requirements in size, weight, torque and reliability. Design is robust against uncertainties associated with material properties, manufacturing and analytical models used.Project 2: DESIGN OF COMPOSITE STRUCTURES THROUGH DECISION SUPPORT PROBLEM AND MULTISCALE DESIGN APPROACH - Developed a design strategy for designing composite structures that are robust against uncertainties associated with design parameters. Studied how the uncertainties at microstructural level impacts the bulk properties at structural level and consequently the structural performance. Illustrated the strategy for designing composite structures for varying load cases. Problem involved concurrent selection of material for skin & core and multiscale design approach.Project 3: CLASSIFICATION AND EXECUTION OF COUPLED DECISION PROBLEMS IN ENGINEERING DESIGN FOR EXPLORATION OF ROBUST DESIGN SOLUTIONS - Proposed a framework for identifying and classifying coupled design problems encountered in engineering design. It helps to explore all possible decision scenarios to address interactions among decisions in coupled engineering systems. Show less

Project 1: Robust Design of Composite Structures - Developed a design strategy for designing composite structures that are robust against uncertainties associated with design parameters. - Studied how the uncertainties at microstructure level of lamina impacts the bulk properties at structural level and consequently the structural performance. - Simplified the analytical model for analysing 2D Triaxial Braided Composite reported in a paper. The simplified model allowed us to study the effect of braider angle, amplitude and wavelength on composite properties. Project 2: Physics based modelling of a thermal power plant. - Investigated the discrepancies between sensor temperature data and results from physics based model. Narrowed down the discrepancies by optimizing the model and predicting efficiencies for all associated sub-systems. Show less

Design Engineer (R&D)

• Jun 2014 - May 2017

Developed a disc coupling design targeted for Japanese railway industries. Responsibility included design calculations, modelling & analysis, writing test protocols, functional prototyping & testing and documenting. Established theoretical calculation model for relating disc design with coupling operating parameters including torque, speed, axial & angular misalignment and, torsional & axial stiffnesses. Established static and fatigue failure limits. Designed an experimental setup to carry out functional testing to validate the calculation model. Prototyped and tested a fastener with fastening mechanism through interference fit. Conducted destructive and non-destructive testing for materials, components and assembly (Disc & gear coupling). Designed fixture for boring precision holes in discs. Fixture was adaptable to 5 disc designs of different sizes. Developed Excel Program using VBA to select and/or explore feasible designs. Capability included selecting disc pack designs (for standard couplings) and exploring disc pack designs ( for non-standard couplings) for given torque, speed, torsional & axial stiffnesses, and misalignment requirements. Identified the cause for rapid failure of burnishing tool and non-conformance of parts produced by the tool. Rectified issue with burnishing tool which led to decrement of scrapped parts and improved tool life. Performed design of experiments for establishing the optimized machining parameters for burnishing process. Theoretical investigation on the impact of shot peening a fully hardened steel sheet. Explored materials and manufacturing alternatives for production of flexible discs based on precision requirement for assembly, cost and rapid production including water jet, laser cutting, punching, etc. Experience with API 610 and API 671 standard for designing gear and disc couplings. Familiar with the API 671 guidelines for balancing couplings. Show less
