Analysis procedure includes A to B comparisons as well as comparisons with laboratory/road test results.
01/2000- 12/2001 Tower Automotive, Hyderabad, India / Novi, USA
About Tower Automotive: This is wholly owned by Tower Automotive located in Detroit (Novi) USA. We are the suppliers of automobile parts on module basis to companies like GM, FORD, CHRYSLER, and NISSAN etc. We will do design, analysis, testing and manufacturing. Our main products are space frames, suspension system, control arms, body panels etc. We are also offering engineering services in and around Detroit area.
My Responsibilities as Team lead include FE modeling and analysis of chassis, coordinating a group of people in meshing and assembling the components. Executing the Global modal and stiffness analysis. Local stiffness, linear and nonlinear analysis on different components of the chassis. Tuning the frame for target values by changing geometry, cross members, type of sections, adding stiffeners, gauge change etc. This involves some revisions / versions to reach prototype stage and final production. Communicating the results, status of analysis to the other group members. Interacting with designers, Product development leaders of manufacturing and testing group.
My involvement in Tower Automotive is in 2003 release Nissan ZW project. This project involves total five frames, one Sports utility (SUV) and four Pickup(PU) versions. Whole team working on this project is located in Novi, USA. I am working from Hyderabad branch. I am actively involved with our group members from here in the meshing and analysis of both PU and SUV models for mashing and analysis.
As a part of training program, I was in our Novi Technical Center for three months. During that period, I had a chance to participate in the presentations/discussions with the customers from Nissan. I had visited our manufacturing, testing, tooling facilities and Tower R&D facilities such as Hydro forming / simul-forming.
01/96 - 07/98 and 03/99 - 12/99 Project Engineer EMRC INDIA, Bangalore, India
About EMRC: Basically a software development firm. Its product, NISA family of Finite element programs, with different modules covering Automotive, Aerospace, Energy & Power and Civil engineering fields. Its operations include software development, sales, executing consulting work, customer support.
My Responsible as a consulting engineer, executing time bound consulting projects, interacting with clients, detailed documentation, testing new software modules etc. Here is list of few projects executed during that period
* Parametric modeling, Static and Dynamic analysis of Cooling water pump (CWP). The assembly of CWP consists of components, which include bell mouth, impeller and its vanes, stator vanes etc., elements of different sizes, intermediate support, distance piece assembly, motor stool assembly etc. Model is analyzed for static deflections, natural frequencies and dynamic responses at critical points.
* 3D Modeling and stress analysis of two wheeler Crankshaft solid model. The typical model of Crankshaft includes the key way holes provided on both sides. This model is tested for entire torque, assumed on (a) the drive end (b) magneto end
* Flow simulation in a Centrifugal pump (Volute and Impeller). Solid model of volute and impeller are created to study the flow characteristics inside the centrifugal pump. Here the volute casing is stationary and impellers are rotating at the specified speed.
* Finite element analysis of Human Tooth and adjoining structures. A two dimensional model of tooth and bone is created to estimate and study the effect of orthodontic forces applied during the treatment. One more study on 3D human skull was done to study of effect of periodontal forces for controlling the bone growth. These two studies done for dental college in Dharwad.
* 3D Modeling of Dipper end casting. This is an overseas project from Wilde Partners, UK.
* Structural Integrity of Paradrop structure. A Paradrop structure consists of steel and aluminum alloy plates are modeled using composite element, analyzed for stresses and deflections when it is suddenly dropped from aircraft.
* Parametric modeling of Pump and sump. The main idea in developing this parametric model is to create the experimental 3D model of sump with three pumps for fluid flow analysis.
* 3D modeling and analysis of Fluid domain of a Valve. Fluid domain of valve geometry was modeled and analyzed for flow pattern along the valve from inlet to outlet.
* Static and Dynamic analysis of Alternator. Complete alternator (Stator + Rotor) was modeled and analyzed for stresses and deflections under short-circuit condition, during lifting. Frequency response analysis has been done with ground excitation and normal operating conditions.
08/98 - 02/99 Project Engineer EMRC WEST, Torrance, California
Consulting work, testing of new software modulus, documentation, and customer support.
* Worked on fluid consulting job, a runway problem from Santa Monica Airport. Contour of a typical runway (includes a hill) at the take-off position was modeled to study the flow characteristics. An imaginary wall was considered to reduce the fluid velocity and to change the fluid flow direction.
* Worked on CFD Analysis of Drill bit to obtain the flow characteristics of coolant through a drill through which a hole runs down the center of a drill and bifurcates at the end.
11/93 - 12/95 Project Associate, BHEL, R.C.Purram, Hyderabad, India.
The work involved during this period was modeling and analysis of various industrial components using NISA & ANSYS. A few to name are steam turbine, turbine rotor, compressor casing, turbine blading etc.
* Centrifugal Stress Analysis of Low Pressure Steam Turbine Blading. A Parametric program developed for automatic generation of Low Pressure Steam Turbine blades using solid as well as shell elements. This program is written for NISA/DISPLAY III.
* Stress analysis of Casing-Nozzle intersection, a parametric study. The aim of this project is to get the optimized dimensions for the Casing-Nozzle intersection with minimum stress concentration at the junction (using a parametric program).
* Design of Fabricated Compressor casing. Compressor casing of horizontal split type was modeled for analyzed deflections and contact stresses at the parting plane. The loading conditions are internal pressure and blot tightening torque
