Sliding Contact Bearings

Growing ecological and economic pressure leads to ever higher and more complex stresses in the development of plain bearings. The research at the institute is therefore primarily concerned with the investigation and development of alternative sliding materials and the influence of geometric deviations. The main focus of the investigations is the wear behaviour under the most varied operating conditions (particles, mixed friction, hydrodynamics).

Evaluation, qualification and estimation of wear of plain bearings in the fields of hydrodynamics, mixed friction, dry or solid state friction. In addition to the stress, the geometry and the material, various influencing factors such as layer structure, shape deviations and surface quality are at the centre of the considerations. But also the accompanying material optimization/new development belong to the central research points.

Simulation with ALP3T coupled with ABAQUS and visualization with Matlab to observe structural deformations.
The example shows a roundness deviation in the form of a uniform thickness with orientation changing from 0° to 120°. The pressure and temperature curve are shown. Sliding Contact Bearings Tools
Validation of simulations through tests on the test benches GLP30 and GLP110. Furthermore, the tribological properties and performance in the plain bearing system are evaluated.
