Analysis of Effect of the Tire Inflation Pressure, Inflation Fluids, Load and Speed on Tire Performance 2019-26-0368
There are various losses associated with passenger vehicle that affect its fuel economy as it is being operated. These losses include engine, driveline, aerodynamic and rolling losses. While engine, driveline and aerodynamic losses are inherent with the vehicle due to large number of parts that go into assembling, rolling loss is associated with the vehicle tires and it is the only part of the vehicle that comes in contact with the road. The rolling resistance of inflated tires is an important component of rolling resistance to vehicle motion and contributes to vehicle fuel consumption. Hence the effect of tire parameters such as inflation pressure, speed and load are the subject of much current interest. Also effect of type of inflation fluid on tire performance is a need of investigation.
This work is focused on the design and development of tire testing setup to test the tire performance parameters like rolling resistance and tire temperature by varying the load, speed, inflation pressure and inflation fluids. Tire 135/70 R12 65 S has selected for testing. The test has conducted under various loads, speed, inflation pressure and inflation fluid air and nitrogen. The result of experimental analysis shows that there is increase in rolling resistance and tire temperature with increase in speed and load. Also, the rolling resistance and tire temperature increases with decreasing the inflation pressure.
For determining the better performance of tire between air and nitrogen, the test has conducted by varying the inflation pressure, load and speed. The result of experimental analysis shows that nitrogen gas having lower rolling resistance and tire temperature comparing with the air.
