The boundary element flexibility matrix method is used to solve the frictional contact problem. The solution method and the convergence criterion are discussed. The calculation program is also developed. The method combines the advantages of the BEM method and the flexibility matrix method. The method is simple and easy to solve High accuracy and fast iterative solution process. · The example analysis shows that the influence of the friction coefficient on the size of the contact area, the adhesion and sliding area distribution and the tangential force is greater than that on the normal force. When considering the influence of friction, the normal The force is slightly larger than the normal force which ignores the influence of friction, the contact area is slightly less than the contact area which ignores the friction; when the friction coefficient increases, the contact area decreases, the adhesion area expands relatively, the sliding amount decreases, the tangential force and normal force increase
