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.
► A setup is developed for the large-scale testing of composite journal bearings. ► Mixed Lagrangian–Eulerian method is used to simulate the setup. ► The contact area is measured with pressure indicator films. ► Effect of clearance on the contact stress and kinematics is investigated numerically. ► The contact stresses are influenced by a minor variation of the clearance.
