Abstract

Thermoelectric Regenerative Braking System (TERBS) employs an energy recovery mechanism by utilizing the energy conversion at the time of braking in an automobile to generate electricity accordingly. During braking, the kinetic energy of the disc rotor which is transformed into heat energy is recovered using a Thermoelectric Generator (TEG). A comparison of performance between air and water cooled heat sink is made and then the optimum way of cooling is selected for the TERBS. A customized TEG module with water cooled heat sink is designed. The experimental results are analyzed for optimum performance. TERBS evidently increased the life of a battery.

Abstract

At many building sites there isn’t sufficient space to manoeuvre the dumper in various directions to discharge the material to the front and side ways. In such situations, there is a growing demand of multi-axis articulated dumpers. This work deals with the fabrication of scale down prototype of three way dropping dumper wherein the dumper is operated using pneumatic tilting mechanism. There are three hydraulic cylinders which are operated by motor and gearbox to tilt the dumper body in all three directions. To maintain optimum efficiency of pneumatic system, the pressure drop between generation and consumption of compressed air is kept very low. Based on the initial prototype and tilting trials, it is demonstrated that this multi-axis system can be fully implemented in large scale. Further, the proposed pneumatic system can be automated with additional control system replacing the socket-pin arrangement to change the tilt directions with minimum human intervention.
