Measurement of Drive Characteristics of Sideslip Tires : 2nd Report, Measurement of tire characteristics on concrete roads

Abstract

The measurement system described in a previous report was applied to examine the sideslip characteristics of block tires for uneven grounds, driven on concrete roads. Two dimensional polynominal equations were proposed to make approximate expression of the relationships of the slippage and sideslip angle to the driving force, side force and axial torque. The characteristic equations were used for numerical confirmation of the local and wide range stabilities of the measurement system. The approach was, also, found to be effective in analyzing the sideslip behavior of a vehicle. The measurement system proposed in the present study has the following features. (1) Measuremests on real roads are possible without a large equipment. (2) The system operates on simple principles and requires no special component force meters. (3) Measuring four wheels simultaneously, the average characteristics can be obtained.
