Title: Towards sensorless operational state monitoring
Speaker: Prof. Dr.-Ing. Eckhard Kirchner, Technische Universität Darmstadt, Germany
Date & time: 20th March 2025 (Thursday), 4PM
Venue: MMCR, Dept. of Design and Manufacturing, Indian Institute of Science (IISc)
Abstract:
After a motivation of the concept of operational state monitoring the benefits of so-called sensor integrating machine elements are explained when it comes to the necessity of gaining information out of the core of mechanical processes. The requirements on a sensorless sensing technology are discussed. The concept of sensory utilizable machine elements is scrutinized both for rolling element bearings and for involute gears leading to an assessment of the respective measuring technologies to analyze the operational state of the machine elements. An outlook on sensor integrating machine elements as an alternative concept for highly integrated data acquisition concludes the presentation.

Speaker bio:
Prof. Kirchner, born 1969, studied mechanical engineering and applied mechanics from 1990 to 1995 at the Universities of Technology in Darmstadt, Germany, and Trondheim, Norway. He received his PhD (Dr.-Ing.) in Mechanical Engineering from Darmstadt for a thesis on shape optimization in nonlinear solid mechanics. Afterwards, he spent 16 years in the automotive industry with increasing management responsibility. He joined Opel, at that time part of the GM group in powertrain simulation are, moved to powertrain design, transmission analysis. After a project management position in global advanced transmission development, he took responsibility as global head of transmission shift systems. In 2011 he left GM and joined Schaeffler Technologies in the area of electric mobility where he had different positions in advanced development. His last industrial station was senior technology manager transmission systems in the vehicle electrification unit of Siemens. Since 2016 he holds the chair for product development and machine elements at TU Darmstadt, he is a board member of the German scientific society for product development and spokesmen of the special research program “Sensor integrating Machine Elements”. Since 2023 he is also Dean of the Faculty for Mechanical Engineering.
