Growing attention has been paid to surface texture owing to its significance in bearing lubrication, load capacity, and wear resistance. In this paper, research emphasis is placed on the influence of texture distributions on bearing vibration and rotor stability. With microfabrication techniques, three kinds of textures configurations (0–90° partial distribution, 0–160° partial distribution, and 0–160° full distribution) are designed and applied on the lower pad surface. The experiment of journal bearings is carried out. The experiment results show that there is a significant decrease in acceleration amplitude of the textured bearings compared to nontextured bearings. Furthermore, the 0–160° partially distributed journal bearings have better vibration damping effect than another two kinds of textures, which can be verified by the shaft center orbits, Fourier spectrums, and waterfall plots.
Reservoir resettlement management is the fundamental project to the success of construction of reservoir. Due to the diversity of types of engineering data and trivial content as well as wide range of covers, modern technologies like GIS are required to build the information system and to achieve systematic management of data which can be displayed through diverse methods in order to satisfy requirements of people from different backgrounds. This paper introduced the application module of reservoir management system and gave an example of practical application in Guangdong Province, aiming at demonstrating high effectiveness, systematicness and convenience of modern technologies in reservoir resettlement project management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
