Reduction of Energy Consumption for a Tire Test Room Through Efficient Heat Management

The current issue highlighted by Continental Tyres (PJ) Sdn Bhd is maintaining temperature stability and the time taken to reach the desired test temperature for the tire test room is long. The problems from Continental originate from the heat generation from the tires during endurance test. In the endurance test, the tires are tested by spinning the tires on a wheel drum with additional load added to the tires with each period, this causes the heat to be generated by the tires due to rolling resistance from the tires at an extended period of time which increases the temperature of tire test room beyond the desired temperature range. It is understood that majority of the rolling resistance is caused by the internal friction or the hysteresis loss of materials, whereas the other factors are road friction or aerodynamic drag. The purpose of this research is to maintain the temperature stability of the tire test room at the most efficient manner and reach the desired test temperature range at the most efficient manner through the study of heat management in rooms. The method of performing the research for this study is mainly by performing Computational Fluid Dynamics (CFD) simulation through ANSYS fluent. In the simulation, the key parameters such as the location of heat sources, heat produced by heat sources, dimensions of room will be used to produce a 3D model, then the airflow and heat distribution in the room will be analyzed and compare to the actual situation using temperature probes to validate the simulated model. Based on the analysis, possible solutions and methods may be identified and then investigated as to their effectiveness. This will be done by modelling the proposed improvements into the existing validated CFD model and simulated to determine the feasibility. If found feasible, the solution will be proposed to Continental for consideration. The expected outcomes from this study is that Continental’s challenge in maintaining the temperature stability in the tire test room in the most efficient manner will be solved. In addition, the time taken to reach the desired temperature range for testing will also be reduced. Both of these outcomes are expected to be achieved with the least possible power consumption.
