| Abstract: | The 3 -freedom mathematical model is deduced for the contact stress of the hub bearing unit.On the basis of this and DFP iterative method,the numerical computations on the contact stresses are carried out for second generation hub bearing unit,and the computational results are obtained under different loads.The computed contact stresses, the radial and axial load capacity are analyzed and discussed,and the effects of the load on contact stress and suggestions are given. |
