As railroad bridge is one of the most important infrastructures of railway, the safety of bridge has a direct effect on railway operation efficiency and safety. In this paper, we propose a distributed railway bridge monitoring platform based on the Internet of Things (IOT) to monitoring the state of bridge safety. We made detailed research on the sensor nodes deployment, sensing data updating and early warning mechanisms of the wireless sensor network. The proposed system achieved the desired purpose of real-time monitoring of railroad bridge safety during test in China Railway Corp. © 2014 SERSC.

The Simplified model of both calculating leakage magnetic field and mechanical force of windings at short circuit condition for a 120MVA/220kV power transformer is set up. The leakage magnetic field, short-circuit force and stress in transformer windings are analyzed and their distributing characteristics are acquired respectively by using FEM. The calculation method and results are validated by withstanding short circuit strength test of the product. A number of useful suggestions are given for design of power transformers.

Information management of road's elementary data will play a more important role for accident treatment, disaster relief, data management, engineering construction and others. In this study, we use the MapX and VB programs, the database of road property is designed and the methods of data's input, edit and building of Geoset object are all analyzed. The functional modules, including file management, view operation, select query, object editor, are established and the embedded procedures are all analyzed, too. Based on this, the information system are developed which can realize the information management of road basic data. © 2013 Asian Network for Scientific Information.

This paper is based on ANSYS finite element analysis software for the platform. It gets the hoister spindle device overall assembly analysis by the finite element theory and method, and gets the overall stress and strain of convective cloud. It is the foundation for further overall structure optimization design and assembly analysis research. It gets topological optimization analysis for the board of the picture of drum, and gives humanoid pore model board important reference value. It provides effective theoretical basis for mine hoist spindle devices the whole optimization design. © (2014) Trans Tech Publications, Switzerland.
