Abstract
The detailed analysis of the tire loading and the subsequent deformations under operational driving conditions is of great importance for the basic investigation of the functionability as well as for the input and verification of the computer simulation of tires. Such data are also required for definition of mission profiles as well as for the derivation of programmes for the durability approval. The principles for the measurement of local strains with adapted strain gauges for large deformations and for the measurement of global tire deformations by spring loaded deflection transducers arranged between the fire crown and the rim are introduced. By combination of those sensors with wheel force transducers the determined tire deformations are referred to the actual service loading conditions. The sensors and transducers are described and examples of field measurements on passenger car and truck tires under distinguished driving conditions are presented.
