The paper takes a type of flexible air bearing as the research object, and structure is analyzed in detail. Combined with traditional analysis method tilting pad fluid-solid coupling theory, new model for performance prediction was established. inner diameter 70mm calculated by changing input pressure or inlet capillary diameter. optimized analyzing calculation results, separate nozzle added. A...

In the broad framework of degradation assessment bearing, final objectives bearing condition monitoring is to evaluate different states and estimate quantitative analysis degree performance degradation. Machine learning classification matrices have been used train models based on health data real time feedback. Diagnostic prognostic driven perspective in prior research work improve assessment. ...

Rolling bearing is main part of rotary machine. It is frail section of rotary machine. Its running status affects entire mechanical equipment system performance directly. Vibration acceleration signals of the third finishing mill of Anshan Steel and Iron Group wire plant were collected in this paper. Fourier analysis, power spectrum analysis and wavelet transform were made on collected signals....

Soil reinforcement can be considered as the combination of two parts. One part is soil for compressive stress capacity and another part is some material such as geosynthetics such as steel belts and fibers for tensile stress capacity. Soil improvement is one of the useful methods to increase the strength parameters of the soil. The main goal of this study is to evaluate the effects of GFRP on t...

Air bearings are used in precision machines and measurement equipments for recently years. Unlike conventional ball or roll bearings, there is no physical contact between the sliding surfaces and the moving surface. Therefore, the structure with air bearings can glide smoothly on the other surface to avoid generating the small particles from the friction contact and also minimize the control ef...
