GPA-3.65/4

• Identified and modeled a solution for problem occurring in a commercially produced Anemometer by NRG systems. • The Anemometer had post calibration errors, problem being identified as precessional rubbing at contact surfaces (bearings). The idea was used to investigate similar phenomena in real sized Turbomachinery bearings. • Modeled mathematical model for such a case and analyzed it for its vibrations signatures. • Whipping and whirling frequencies (Reason for anemometer error) were analyzed and validated using a nonlinear time transient analysis for the same model Project -Precessional Whip and Whirl Characteristics for a model with contact at 2 rub locations for rigid rotor supported on a elastically supported rigid stator.

Summary

Mechanical Graduate with a proclivity towards innovative ideas and interests in design and machinery. • Developed a model for rubbing at bearing contacts to study precessional rub phenomenon exhibited by anemometers and extended this study to real size Turbomachines. • Designed a reaping tool which replaced conventional rotary mechanism with a reciprocatory one (increased efficiency). • Designed pressure vessels as an intern at Larsen and Toubro (oil and gas special project division). • Expertise in using automated mathematical solutions, to simulate motion/stresses for various projects.
