A complete numerical solution to the problem of the EHEL contact is proposed. By means of the inverse solution iterative method, the oil film pressure distribution, oil film thickness and oil film shape under different operating conditions are obtained. In the process of calculation, the deformation matrix is introduced to calculate the elastic deformation, and the deformation of the pressure distribution is corrected by the deformation inverse array. All these have achieved satisfactory results. The proposed calculation method is suitable for solving the heavy-load line contact problem often encountered in engineering practice. The maximum Hertz contact stress and the pressure-viscosity coefficient of lubricating oil in the calculation result are 38.93. The conclusion is basically the same as that of Dowson et al.
