Design of Artificial Hip Joint Test Rig
Dočkal, Kryštof ; Košťál, David (referee) ; Vrbka, Martin (advisor)
In this thesis, is described one of possible approachs to the design of the hip joint simulation rig, primarily designed for analysis of the lubricant film thickness at the contact of two conformally curved surfaces (femoral head and acetabulum). In relative motion of those two components of artificial hip joints is necessary to observe the behavior of lubrication film between them. The observation is also related to choice of appropriate observational method. In the design of the artificial hip joint is today primarily used wear simulations on smulations rig with very accurate simulation of kinematics of biological hip joints. For description of the behavior of the lubricants between conformall surfaces is used a simplified kinematics along with optical interferometry. The simulation rig will be able to study behavior of lubricant layer using optical inteferometry,
