Research Scholar’s Day is a yearly event organized by the Department of Mechanical Engineering to showcase graduate research from the department, with poster sessions by final year M.Tech. students and talks delivered by senior Ph.D. candidates on their ongoing research efforts. The purpose of this event is to promote research awareness among the new postgraduate students and foster student-faculty interactions. This event includes the R.S. Pandey Lecture Series delivered by distinguished experts in the field.

Title: Effect of Initial Perturbations on Stability of Autonomous Bicycle — A Graphical Approach

Speaker: Prof. N.N. Kishore

Abstract:

The present paper attempts to perform a quasi-dynamic analysis of bicycle stability from the viewpoint of initial perturbations and understand the stable and unstable behaviours. As earlier researchers did, the bicycle is idealized as four interconnected bodies—the front wheel, the front fork, the main body, and the rear wheel, all joined by revolute joints. The forces acting on the bicycle are limited to its weight, centrifugal forces, and gyroscopic moments. The two primary degrees of freedom analyzed are the bicycle's lean (tilt) angle and the front wheel's steering angle. A systematic MATLAB simulation analysis illustrates the results through trajectories, phase plots, and moment contours. This graphical approach helps to identify the effect of small but finite initial perturbations on the stability, offering intuitive insights into the nonlinear dynamics governing self-stability.

About the Speaker:

Prof. N. N. Kishore has been a faculty member at IIT Tirupati in the Department of Mechanical Engineering since January 2016. Earlier, he worked at the Indian Institute of Technology, Kanpur, as a faculty member for 31 years. He obtained his B.E. from Andhra University in 1971, and his M.Tech. and Ph.D. from the Indian Institute of Technology, Kanpur (Mech. Eng.) in 1974 and 1980, respectively. He worked as a Post Doctoral Fellow at Drexel University, Philadelphia, from 1980-84. He also interacted with the Institute of NDT in Saarbrücken, Germany, on NDT research projects. His major areas of interest are in Wave Mechanics, Composite Materials, Finite Element Methods, Non-Destructive Evaluation, and Dynamic Fracture Mechanics. He guided several Ph.D. students and published technical papers in national and international journals. He served IIT Kanpur in various administrative capacities as Head of the Department of Mechanical Engineering during 2001-04 and as Professor-in-Charge of Administration during 2015.
