  Graduate research assistant

  * Topology optimization of a Curved Thermal Protection System (TPS) panel for the future space shuttle orbiter, in the presence of high thermal stress and heavy acoustic loads while re-entering the earth’s atmosphere, in the presence of geometric nonlinearity is performed. This project is funded by Wright-Patterson Air force Base (WPAFB), Dayton* A topology optimization package is developed in MATLAB. TPS panel is simulated with re-entry thermal loads and the topology design is performed to reduce the thermal stress and increase the fundamental natural frequency. This project is funded by Wright-Patterson Air force Base (WPAFB), Dayton. * Sizing optimization of an Intermediate Complexity Wing (ICW) is performed, to reduce the weight, by considering the flutter and stress constraint.

  Apr 2006 - Nov 2006

  Contract chassis cae engineer

  * Performed modal and durability analysis, to see performance of the oil cooler bracket. The natural frequencies of the proposed bracket are compared with the current bracket, to determine the vibration performance of the proposed bracket.* Proposed design of the splash panel bracket is analyzed for its modal performance, and the durability of the bracket is estimated by applying lat, longi and verti 'G' loads and observing at the peak von Mises stress in each load case. * Bead Optimization of the splash panel is performed to increase Natural frequencies, to keep the natural frequency of the assembly away from the frequency of the engine vibrations and road shocks.* Topology Optimization is performed to suggest a new topology design of the hood mount, with displacements and frequency constraints.* Durability analysis was performed using LifEst on a new proposed X-member, that absorbs load that has been transmitted from the axle to the torque rod and the X-member.
