ACADEMIC EXPERIENCE

• Design Analysis using ANSYS – Static, Harmonic, Modal, Transient, Nonlinear, Solid Modeling and Contact Problems,

Active vibration Control, Numerical Integration Methods – Central Difference Method, Newmark’s method and Newton-

Raphson method for large deflection nonlinearities.

• Manufacturing Systems, Lean Philosophy, Supply chain Networks, Bar-coding techniques.

SIMULATIONS

Active Vibration Control (AVC) using ANSYS

Current Project - Application of AVC to a single-stage axial-flow low speed research compressor (LSRC) to

reduce vibration amplitudes of Rotor blades and Stator Vanes.

Proof of Concept – Reduced externally induced harmonic vibration amplitudes in a cantilever beam.

• Modal Analysis of the cantilever beam.

• Modeling of Piezo-electric patches on the cantilever beam to control the system response.

• Sub structural analysis of the setup to import the stiffness, mass and damping matrices into matlab.

• Application of Feedback controls theory to show the reduction in the aforesaid vibration amplitudes.

• Experimental verification of the above simulation work.

Nonlinear Transient FEA of a Cantilever beam parametric response including quadratic damping

• Implicit and Explicit Nonlinear harmonic transient analysis of a cantilever beam to study parametric response.

• Application of Quadratic damping methodology to substitute the ANSYS inbuilt damping module.

• Variation of quadratic damping coefficients over a range of excitation frequencies to study the effect on the

steady state amplitudes.

Academic FEA Design Optimization Projects

• Geometrical and cost optimization of a plastic bracket meeting the maximum Von Mises stress,

deflection and material criteria.

• Dynamic modeling of a multi degree freedom system under the influence of externally applied force.

• Modal analysis of a compressor rotor blade using 3D elements. The primary design goal is to minimize

blade weight while eliminating the interference condition and meeting the maximum radial deflection criterion.
