Burst Test Simulation for bias Truck Tire

摘要

A model of a pneumatic bias tire based on the technique of overlaying the orthotropic reinforcing elements on isotropic rubber elements is presented. Incompressibility of hyperelastic rubber, tire contact with the rim as well as thermal shrinkage and non-linear properties of the textile cords were taken into account. The effectiveness of the model was verified in the simulation of a hydrostatic burst test of a bias truck tire. The model is extremely numerically stable and allows assessment of strength of load-bearing elements, i.e. cord plies and bead wires. The influence of neglecting cord shrinkage and cord characteristic linearization on simulation results were also investigated.
