Abstract：Aiming at the inaccuracy of the finite element analysis(FEA)of heavy-duty engineering wheels under the radial loading condition,a new simulation analysis model based on the results of wheel-tire contact pressure test was established.Firstly,a stress data corresponding to the wheel under inflation pressure condition alone undergo testing,and a loading model for inflation pressure was formulated using a Gaussian function of 4th order.Secondly,a stress data collected while the wheel experiences combined inflation pressure and radial load were analyzed.The influence of inflation pressure was isolated,allowing for the development of a circumferential loading model and an axial loading model for the radial load,using a Fourier function of 4th order and a sinusoidal function of 4th order,respectively.Finally,the validation of the loading model was conducted through Ansys simulation.The outcomes demonstrate the calculation error of mere-approximately 1.943%in relation to the measured data for the key calibration points.Additionally,the observed stress distribution manifests a remarkable degree of consistency.This substantiates the accuracy and reliability inherent in the proposed radial contact pressure distribution model.
