Malrotation of the femoral component is a cause of patellofemoral maltracking after total knee arthroplasty. Its precise effect on the patellofemoral mechanics has not been well quantified. We have developed an in vitro method to measure the influence of patellar maltracking on contact. Maltracking was induced by progressively rotating the femoral component either internally or externally. The ...
It is industry tendency to accurately predict the dynamics of mechanical systems with full consideration errors. Based on Hertz contact theory and general bearing modeling methods, this study proposed a more practical model using numerical method investigate influence assembly error linear guide slide platform. First, methods five types errors are established, based which, nonlinear dynamic dev...
In a recent Letter, Persson [1] suggested a new model of contact between arbitrary randomly rough surfaces. He considered also fractal surfaces which he characterized above the lower cutoff only by their dimension Df and an additional constant. He argued that in the framework of the model, the area of real contact A in most cases is proportional to the load P. However, there are examples which ...
