This paper deals with hydrodynamic bearing stability analysis based on a parametric model in the scope of monitoring intended for rotating machinery under transient operating conditions. The aim of the presented approach is to provide diagnostic symptoms of faulty conditions. The study is supported by analytical consideration, laboratory measurements, physics-based and data-based models. Mathematical model and test rig were used to simulate vibrations of a shaft supported with hydrodynamic bearings under normal and malfunctioned operation. The conducted simulations for a single mass system were utilized to validate the proposed diagnostics approach. Advanced signal processing is realized with the rapid prototyping tool, i.e. Matlab and digital signal processing hardware.
