• Polymeric composite bearing
• Clearance
• FEM

The effect of the clearance on the contact stresses and kinematics of a polymeric composite journal bearing is investigated. To this purpose a test rig is devised, which is capable to measure the tribological characteristics of the large-scale composite bearings. Kinematics of the setup is simulated by a 2D FE model. Moreover, to evaluate the contact area between the bearing and shaft, pressure indicator films are used and a simplified 3D model is provided. Simulation results correspond closely to the experiments and it is shown that the clearance variation can have a big impact on the contact stresses distribution.
