The necessity to obtain greater production, lower fuel consumption and lower emissions of pollutants is typical interest factors in the development of machinery and equipment. For this reason, the pursuit for more efficient machinery has been increased in recent years, aiming to obtain greater productivity and comply with the regulatory standards of consumption and emission. Therefore, th…
Hydrodynamic bearings occupy a prominent place in industry due to their significant influence on the dynamic behavior of the rotating system. Among the types of hydrodynamic bearings, the most widespread is the radial cylindrical bearing, which has low manufacturing cost, high load capacity, low frictional energy losses, and long operating life. Despite the advantages already highlighted,…
Adequate oil supply is mandatory for optimal operation of hydrodynamic bearings, however many rotating systems in operation do not have sensors to individually measure oil supply flowrates and, eventually, identify failures in the bearing lubrication system. On the other hand, measuring the vibration of rotating machines is a basic procedure and present in any maintenance program for this…
Hydrodynamic bearings play a crucial role in the life cicle of rotating machines, as they represent one of the most critical sources of faults in these machines. In addition, the faults identification in hydrodynamic bearings is still challenging in the current scenario, since it is not completely known how these specific faults can influence the rotor dynamic response.Within this context…
This research project aims to develop a new concept of hydrodynamic bearing capable of improving the performance of rotary machines by preventing the condition of fluid-induced instability, reduction in bearing temperature and control of their load capacity. A model of the hydrodynamic bearing will be developed to allow the rotation movement of its surface, thus allowing to change the ave…
Among the faults considered in rotary machines is the cavitation in hydrodynamic bearings, capable of causing serious problems to the rotor, such as increase of vibration, metal-to-metal contact and even bearing wear. For this reason, it becomes imperative to identify, as soon as possible, when a machine is operating in cavitation condition, in order to actuate quickly in the system and t…

Rotating machines demand a precise understanding of their dynamics to assure safe andhigh performance design. Besides the design study, faults can occur during operation andaffect the system dynamic, hence understanding faults effects on such systems areessential to early detection and to reduce maintenance costs. In this context, monitoringvibration patterns and numerical models are usef…
