Experimental Study on Tyre Dynamics and Properties of Heavy Load Transporting Vehicle

摘要

Tyres of heavy load transporting vehicle are stiffer than the other tyres to withstand heavy loads. Tyre dynamics and properties influence the dynamic qualities of vehicles and have an impact on energy consumption of vehicle (up to 7% due to tyre rolling resistance). Study of dynamics and properties of heavy tyre is nothing but study of performance of the tyre during motion with or without load. The handling performance of vehicle depends on the characteristics of tyre-road contact. The horizontal and vertical forces acting on the vehicle are transferred through tyres as a result of steering, braking and driving. The paper presents the results of the experimental study of tyre properties and dynamic forces and corresponding moments calculated by using various mechanical devices and empirical formulas. Test trails were conducted to explore the changes in dynamics with respect to tyre properties and road conditions by changing payloads on the transporting vehicle.
