Abstract

Abstract: During the wear monitoring for the aircraft tire, the expansion change on the top of tire crown caused inaccuracy for the monitoring results. Considering the aircraft tire cord with high strength, orthogonal anisotropy and tensile deformation, the main three dimensional nonlinear finite element model of B737-800 passenger aircraft radial tire was built using the Yeoh rubber constitutive model and the Rebar stiffener unit in Abaqus software. The problem of static contact between aircraft tire and road was successfully simulated using adaptive Lagrange algorithm. Radial tire stiffness, ground imprinting, main area of friction losses and sinkage were obtained by simulation. The problem of the dynamic threshold of sensors during the wear monitoring was solved by the variation curve of the top of tire crown inflation; while the accuracy for monitoring results was improved. The simulation results were compared with the calculated data and the result indicated that the model' reliability was fairly good.
