The unbalance forces due to the lumped eccentric mass are treated as general forces. Meanwhile, the potential energy expression about gravity based on finite element method is presented for convenience. Based on the variational inequalities principle, the finite element is used to determine the film forces produced by fluid film bearing and damper at any moment and its Jacobian matrix with respect to location and velocity of journal and bearing house.

The self-centering mechanism design of bipolar endoprosthesis has advocated the use of offset centers of rotation between the inner and outer joint bearing surfaces to generate a self-centering moment on loading to prevent impingement of polyethylene rim and stem neck or cup fixed at wrong place. The design was used popularly, but the function of self-centering mechanism was discussed in very few papers. Three bipolar endoprosthesis were evaluated: UNIQHIP system, UHR system, and AML system.
