Analysis of Bearing Damage Using a Multibody Model and a Test Rig for Validation Purposes
Abstract
Intensive research, performed over the last five decades, focuses on fault diagnosis of bearings. To investigate the generation of these fault symptoms, this paper discusses the development of a multibody model of a bearing. Localized faults are introduced in the model, aiming to analyse vibration signals of damaged bearings. The paper compares different possibilities to implement these defects. Simultaneously, a test rig is built to validate the model. The rig allows applying a fully controlled multiaxial static and dynamic load on different types of bearings. Therefore, it is a powerful tool to load a bearing as built into a real machine, and measure its response.
