Abstract

A low-cycle fatigue test rig reproduces bearing of turbine engine parts. The test rig includes a support member that is fixed to a frame and defines at least one bearing surface. A test piece is connected to a traction element for loading the test piece so that the test piece bears against the at least one bearing surface of the support member. The at least one bearing surface is supported by a support element that is mounted to rotate about a first axis on the support member. The test piece is connected to the traction element for articulation around a second axis that is perpendicular to the first axis. The test rig is configured to enable adjusting and locking the support element and the test piece in positions around the above-mentioned axes.
