THE TECHNOLOGY FEM simulation is a means of predicting (and optimizing) the behavior of various complex objects.
It is also possible to simulate temperature distribution and electric or magnetic fields or several factors at the same time with multi -parameter simulation. The R&D focus on simulating the thermal-mechanical behavior of bearing.
USES AND BENEFITS
The key advantage of using FE simulation methods is the ability to visualize the distribution of various properties and based on it gain a detailed understanding of the behavior and connections between various factors affecting a system. This enables us to identify a system’s most important design factors and error sources and make the necessary improvements without timeconsuming mass screening of models or similar.
Hydrodynamic journal bearings are analyzed by using Computational fluid dynamics (CFD) and fluid structure Interaction (FSI). For example Journal bearing models are developed for different speeds and eccentricity ratios to study the interaction between the fluid and elastic behavior of the bearing.
