This paper presents a novel underwater localization algorithm fusing the Attitude and Heading Reference System (AHRS) with underwater altimeters to localize the underwater welding vehicles (UWV) in the spent fuel pool of the nuclear power station. The SFP is divided into multi regions according to the attitude of the UWV and the coordinate of the UWV is calculated by corresponding method in each region...
It's considered as a task that a robot welds under the state of emergency and patrols daily in the nuclear reaction pool. A design scheme of underwater welding robot with cables is proposed, which move in all direction, has a function of pitching and absorb on the wall surface by thrust of propellers. In this paper in order to achieve for the precise control of the underwater robot, a dynamic equation...
The stratum of Paleogene System at Shahejie formation 3rd Middle sub-member in Jizhong depression is universal distribution. On the base of the welldrilling, core and quake data etc. as characterization and quantification, the lithofacies paleogeography maps of Paleogene System at Shahejie formation 3rd Middle sub-member in Jizhong depression are compiled with the single factor analysis and multifactor...
