After graduating from Indian Institute of Technology, Kharagpur in 2017 with a Bachelor’s Degree and Masters Degree in Mechanical Engineering, Sneha Rupa worked with Eaton India Innovation Center in Pune, for 3 years. As a Structural Mechanics Engineer, she had the chance to work in niche areas of product design for businesses ranging from power management products to e-mobility.
Her motivation to work in the LIVE-I project is the opportunity to develop sustainable and eco-friendly mobility technologies for the future and shape my ideas through interaction with experts in the field. In addition to research, she is an avid reader, painter and she loves to travel.
This project aims to reduce the vibrations of the transmission throughout the implementation of an active vibration control(AVC) system. The idea is to let the AVC system take care of all vibrations produced by the gearbox, allowing a cheap, light and efficient design of the transmission. The investigationof the overall potentialof weight-, cost-and energy consumptionreductionthroughout the integration of an AVC system into the transmission is one part of the workplan. In order to enable this kind of investigation, one has to implement such a system first. The design of a suited AVC system is the main focus of this project. Many questions arise considering the implementation of such a system which have to be tackled within the project:
- What is the vibration pattern of the gearbox?
- What kind of actuators are suited for this task?
- Where should the actuators and sensors be placed?
- How many actuators and sensor are required?
- What is a suitable control approach?
- How can the system be integrated smart into the transmission?
In order to answer all these questions, simulations will be carried out first. These allow toinvestigate different control strategies and the effect of model uncertainties. Promising approaches will then be implementedon a single stage proof of concept gearbox.
