Aerostatic bearings are widely used in the field of ultraprecision machining. It is well known that orifice restrictor with a recess has higher load capacity and stiffness than inherent restrictor. However, it inevitably brings more serious micro-vibration problem, which probably related to large-scale vortices recess. To this end, suppress aerostatic bearing vibration, we have designed novel micro cylindrical array (RMCA-I RMCA-II) smash vortices. Meanwhile, investigated vibration...
The feasibility of a tubercled leading-edge in dynamic stall control has been validated, and the impacts an upstream cylinder wake have already discussed previous research. However, influences coherent characteristics on process are inevitable. To this end, synthetic turbulence method was adopted present study to generate incoming turbulence. suppression could be observed according shrink hysteresis loop aerodynamic lift. Then, mechanisms analyzed with help mode decomposition method....
The interaction between ultrafast, tightly focused lasers and materials has garnered significant interest owing to its distinctive properties. In this study, we present a versatile methodology for the fabrication of tunable plasmonic nanostructures by employing disordered gold nanoisland-dielectric-metal configuration, achieved through femtosecond laser printing. By reshaping nanoislands reconfiguring them into nanograting-like structures, orientation these is influenced polarization light,...
The directional coupler is one of the most important devices in field integrated optics, from which other optical such as polarization splitters and reflectors are derived. In this paper, we present an autodesign method for based on beam propagation golden section method, can decrease amount computation greatly. Using analyze discuss influence Ti-diffusion conditions structural optimization quantitatively. addition, have fabricated a series experimental results consistent with theoretical analysis.
The structure parameters and the Ti-diffusion of Integrated Optical Polarization Splitter (IOPS) affect performance device greatly. By discussing these two factors quantificationally comprehensively, we obtain a series theoretical conclusions, which are important guidance to fabricate high-performance splitters. In particular, because limitation lithophotographical technique, there must be flat at end V-shape between branch waveguides IOPS. has crucial effect on optimization procedure...
