“…For clarity, the contact formulation is briefly presented here based on the methodology previously published for CoC bearings (Liu et al, ). The IMPACT function in Adams was used for both the edge loading and the articular bearing contact of the cup and head (MSC, ), which can be expressed as follows

F = ({, \begin{matrix} 0, if x > x_{1} \\ k {(x_{1} - x)}^{e} - c_{\max} \overset{x}{true} \cdot STEP ((), x, x_{1} - d, 1, x_{1}, 0), if x \leq x_{1} \end{matrix})

where F is contact force generated at the contact interface either of the cups and head articular bearing surfaces or between the cup rim and the head bearing surface, k is a generalized stiffness, e is nonlinear force exponent, x 1 is the distance calculated by Adams based on the contacting geometry above which there is no contact force, x is the approaching distance between the two contacting objects, d is the penetration at which to apply the maximum damping coefficient c max , the STEP function takes 1 for x = x 1 − d , 0 for x = x 1 , and a cubic polynomial interpolation for ( x 1 − d ) < x < x 1 , and

is penetration velocity.…”

Edge loading that occurs in hip joint replacements due to dynamic separation of the joint bearings has been shown to cause severe wear for meal-on-metal bearings. In the present study, the multibody dynamics model for metal-on-metal (MoM) hip joints with a medial-lateral translational mismatch in the centers of rotation of the cup and head has been developed to predict the dynamic separation and contact force of edge loading under gait loading conditions. The effects of larger head diameters (28-55 mm), in combination with the translational mismatch (0-4 mm) and varied cup inclination angles (45 -65 ), on edge loading of MoM bearings have been computationally investigated. For the given translational mismatch, increasing head diameters results in negligible effects on the dynamic separation, contact force and severity of edge loading. Increasing head size also leads to increased offset loading torque which has been found to reach at the level that may cause cup loosening under larger translational mismatch at 4 mm. The result highlights the importance of the cup inclination angle of 45 and a lower translational mismatch to avoid severe edge loading.

“…Over the past 30 years, many researchers have conducted several efforts to develop bearing of hip joint arthroplasty using the finite element method under walking condition. Several computational simulation software selected to conduct finite element analysis, like ANSYS [ 57 ], ABAQUS [ 65 ], COMSOL Multiphysics [ 38 , 54 ], MATLAB [ 44 ], Adams [ 66 ], and AnyBody Modelling System [ 67 ]. Both bearings of total hip arthroplasty and hip resurfacing have been studied, but mostly doing investigations on total hip arthroplasty [ 68 , 69 , 70 ].…”

The existing artificial joint implants using bioceramic materials face problems of difficulty in manufacturing and premature failure due to wear. This paper investigated a rapid preparing process of ultra-smooth surfaces of yttria-stabilized tetragonal zirconia polycrystal bioceramics based on the dual-axis wheel polishing (DAWP) system. Friction and wear tests were conducted to prove that the prepared ultra-smooth surface can effectively reduce wear. The effects of process parameters on polishing performances were investigated. The XRD and SEM analysis and micro-hardness testing were used to characterize the prepared surface in material behaviors.Tribological tests were carried out on a ball-on-plate reciprocating tribometer to comparatively study the tribological behavior and wear mechanism of the prepared ultra-smooth surfaces and the conventional surface at sub-microscale. The used finishing technology can steadily achieve fast preparation of ultra-smooth bioceramic surfaces, and with a high material removal rate (the highest value was 1.14 mg/min).Besides, in contrast to the conventional surface (Ra 129 nm), the prepared ultra-smooth surface (Ra 0.38 nm) achieved a much smaller friction coefficient, and much less wear volume, indicating that the wear resistance of the ultra-smooth surface was significantly improved.
