A comparison of tire rolling resistant testing machine using force and torque calculation

Abstract

This research aims to study and compare the test results obtained from the rolling resistance tester of automobile tires based on force method and torque method system. The four newly manufactured tires were sampled from two tire classes, namely passenger car tires (Class C1) and light truck tires (Class C2). The tire rolling resistance test according to the international standard UN ECE Regulation No.117 was used as an important research process. The experimental work discovers that the rolling resistance of the same tire obtained from the test between the two different methods of testing machines was not more than 6 percent different. The testing results that used the torque method system calculation are high reliability because of the principle of calculation from the measurement value directly results in. and suitable for research testing. However, the force method tester can perform more than a tire simultaneous test, which is suitable for working in industrial applications where time is limited.
