Magnetorheological Fluid Based Kinetic Energy Recovery System

Hindustan Univ.-Vishnu Gopal

Published 2011-10-06 by The Automotive Research Association of India in India
It has become the need of the day for the evolution of newer and better technologies for various applications. In this paper we introduce a new technique of recovering the kinetic energy which is wasted during the process of braking in Formula one cars. In previous techniques of kinetic energy recovery, the kinetic energy is converted to electrical energy which is stored and later utilized. In this paper we propose a new approach of recovering the energy wasted due to braking by using a flywheel mechanism coupled through magnetorheological(MR) fluid. During the process of braking, the energy is transferred from the wheel to the flywheel(recovery) and during the process of acceleration the energy is transferred from the flywheel to the wheel(reuse). Due to this recovery of energy there is an improved acceleration and a comparatively lesser fuel consumption. The novelty of this proposed mechanism lies in the use of no electrical components such as motor, generator, or battery thereby reducing the overall weight and electrical losses.

Future Main Battle Tank - Mobility Requirement Poses a New Dimension to the Tank Design

Combat Vehicles Research and Development Establishment, Avadi, Chennai 600 054, India-J. Roopchand, B. Rajagopalan
Published 2005-10-23 by The Automotive Research Association of India in India
The Main Battle Tank (MBT) is a mobile weapon platform and its design is dictated by its strategic / tactical and battlefield mobility requirement in the battlefield. Strategic / tactical mobility of the current MBT is by rail or road transportation. The tank dimensions are arrived based on this requirement. The battlefield mobility requirement dictates the vehicle performance like speed, acceleration, obstacle crossing ability etc. But the likely operational requirement of the Future MBT is that it should be rapidly deployable with air transportation capability and high agility. This mobility requirement poses a new dimension to the battle tank design. The Future Main Battle Tank needs to be lighter, smaller, faster and yet it should offer maximum punch on the enemy. This paper describes the current design philosophy, future operational requirement, change in the Mobility concepts of the future MBT, choice and technologies of the propulsion system and suspension.
