Special Issue Information

Dear Colleagues,

Gas lubricated bearings use gas to achieve complete non-contact suspension lubrication, offering advantages such as low friction loss, high precision, adaptability to various working environments, and exceptional stability. Gas lubricated bearings meet the demanding requirements of equipment with extreme performance needs, including ultra-high speeds, precise operation, high efficiency, and long lifespan. Gas lubricated bearings hold promising applications in advanced equipment such as high-speed electric spindles, hydrogen fuel cells, micro-gas turbines, and hydrogen expanders. As the application environments for gas lubricated bearings become increasingly complex, there is a growing emphasis on factors like the lubrication medium, bearing capacity, stability, and adaptability. Lubrication technology for gas bearings encompasses various research areas, including lubrication mechanisms, multi-field coupling flows, structural design and optimization, high-performance manufacturing, performance testing, and system integration.

In this study, in order to reveal the influence mechanism of bearing parameters on pneumatic hammering, an aerostatic bearing with a multi-orifice-type restrictor is analyzed. Firstly, the flow field is investigated, and the vortex-induced excitation is discussed in both the frequency and time domains. Then, the frequency-related displacement impedance is analyzed, and the effects of vortex-induced excitation on pneumatic hammering are discussed. Experiments are also conducted for verification. Moreover, the influence of damping on pneumatic hammering is identified. The results show that with larger damping, the risk of pneumatic hammering can be reduced. Finally, the impacts of design parameters on the damping are discussed in detail using an approximate model. Design optimization is considered to achieve the maximum damping, i.e., the minimum risk of pneumatic hammering. The results show that both the air supply pressure and the pocket volume should be minimized. The analysis process provides a reference for the design of bearings to reduce pneumatic hammering.
