10. Juni 2023 · The term "skeezer" appears in various forms of pop culture, often within the realm of music and film, and typically carries a negative connotation. Let's examine some examples: In the movie Gone Baby Gone (2007), Bubba Ragowski tells Angie Gennaro, "There's reasons why there ain't three inches of plexiglass between us right now.
Bubble dynamics, oscillatory oil squeeze film, cavitation. 1 Introduction . In lubricated mechanical systems, oil is widely used as a thin film to reduce wear and to create damping to eliminate undesirable mechanical vibrations. The phenomenon that oil film may fracture in tensile stress is called cavitation. According to the formation
19. Aug. 2018 · The dynamical characteristics of SFD and dual clearance squeeze film damper (DCSFD) are experimentally investigated in ref. [ 10, 11, 12] Placing an elastic ring inside the oil chamber results elastic ring SFD or ERSFD, as shown in Fig. 1 (a). ERSFD not only retains the advantages of SFD, but also has better performance in suppressing nonlinear ...
5. Sept. 2023 · In order to explore the air ingestion characteristics of the open-ends squeeze film dampers (SFD), a 3D computational fluid dynamics solution model of the SFD was proposed based. The setting of opening boundary conditions was considered, which was verified experimentally by the bidirectional excitation. The results revealed that with the same precession frequency, the smaller radial clearance ...
As a novel structural damper, the unique structural characteristics of the integral squeeze film damper (ISFD) solve the nonlinear problem of the traditional squeeze film damper (SFD), and it has good linear damping characteristics. In this research, the experimental studies of ISFD vibration reduction performance are carried out for various working conditions of unbalanced rotors. Two ball ...
20. Juli 2017 · In dynamic plowing lithography, the sample surface is indented using a vibrating tip in tapping mode atomic force microscopy. During writing, the gap between the cantilever and the sample surface is very small, usually on the order of micrometers. High vibration frequency and small distance induce squeeze film air damping from the air in the gap. This damping can cause variations in the ...
17. Okt. 2013 · In some of the investigations one comes across the application of ferrofluid as a lubricant to analyze the squeeze film performance characteristics of thin film lubricating mechanism [1–5]. Because of the fact that the viscosity of ferrofluid increases when subjected to external magnetic fields, the magnetic fluid lubricated squeeze film results in a higher load carrying capacity as compared ...
