A model is presented of the in-plane behaviour of a radial tyre, suitable to be employed within the simulation of aircraft braking. The model is developed on the basis of an energy-balance approach that allows the determination of the effects of braking on rolling friction and on the lever-arm of vertical load. The model is tuned and validated through the correlation between simulated and experimental results relevant to a large aircraft tyre. The method proposed is tuneable on a specific tyre using a limited number of parameters, that are those usually recorded during standard braking tests and it is extendible to the braking tests of an aircraft. This would overcome the limitations intrinsic of current tyre dynamometer facilities that are able to test large aircraft tyres over a modest range of vertical loads compared with those experienced under service conditions.

Abstract
A model is presented of the in-plane behaviour of a radial tyre, suitable to be employed within the simulation of aircraft braking. The model is developed on the basis of an energy-balance approach that allows the determination of the effects of braking on rolling friction and on the lever-arm of vertical load. The model is tuned and validated through the correlation between simulated and experimental results relevant to a large aircraft tyre. The method proposed is tuneable on a specific tyre using a limited number of parameters, that are those usually recorded during standard braking tests and it is extendible to the braking tests of an aircraft. This would overcome the limitations intrinsic of current tyre dynamometer facilities that are able to test large aircraft tyres over a modest range of vertical loads compared with those experienced under service conditions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
