Rotor Systems

Dr. Rajiv Tiwari was born in 1967 at Raipur in Madhya Pradesh. India. He graduated in B.E. in 1988 (Mechanical Engineering) from Ravishankar University, Raipur and M. Tech. (Mechanical Engineering) in 1991 and Ph. D. (Mechanical Engineering) in 1997 from Indian Institute of Technology (IIT) Kanpur, India.

He started his career as Lecturer in 1996 at Regional Engineering College, Hamirpur (Himachal Pradesh), India and worked for one year. From beginning of 1997, he joined Indian Institute of Technology Guwahati as Assistant Professor in the Department of Mechanical Engineering. He worked as Research Officer at University of Wales, Swansea, UK for one year in 2001 on deputation. He was elevated to Associate Professor in 2002 and to Professor in 2007 at IIT Guwahati. He was the Head of the Center of Educational Technology and Institute Coordinator of the National Programme on Technology Enhanced Learning (NPTEL) during 2005 to 2009, and the National Coordinator of the Quality Improvement Programme (QIP) for engineering college teachers during 2003-2009.

He has been deeply involved in research area of Rotor Dynamics (i.e. especially on Identification of mechanical system parameters, e.g. the bearings, seals and rotor crack dynamic parameters, Fault diagnosis of machine components like bearings, gears, pumps, and induction motor and application of active magnetic bearings in condition monitoring of rotating machinery). His research area also includes rolling element bearing design and analysis for high-speed applications. He has completed three projects from Aeronautical Research & Development Board (ARDB), India on these topics. He has been offering consultancy for last several years to Indian industries like Indian Space Research Organisation (ISRO), Trivendrum; Combat Vehicle R&D Establish (CVRDE) Chennai; Tata Bearings, Kharagpur; apart from other local industries in the northeast of India. One of the European power industries the Skoda Power, Czech Republic has also taken consultancy of seal dynamic parameter estimation for steam turbine applications.

Dr. Tiwari has been author of over 130 Journal and Conference papers. He has guided Thirty Eight M. Tech. students and has guided Seven Ph.D. students and Eight more are pursuing their research at present.

He has organized successfully a national level Symposium on Rotor Dynamics (NSRD-2003), four short term courses on Rotor Dynamics (2004, 2005, 2008, 2015) and National Workshop on Use and Deployment of Web and Video Courses for Enriching Engineering Education (2007) at IIT Guwahati, India. He has jointly organized an International Conference on Vibration Problems ICOVP 2015 at IIT Guwahati. He has developed two web and video based course under NPTEL (i) Mechanical Vibration and (ii) Rotor Dynamics, and under MHRD sponsored Virtual lab on Mechanical Vibration Virtual Lab.
