Abstract: With the large scale high speed railway construction and higher running speed, the complicated electromagnetic environment poses issues on the reliable and safe operation of high speed train. Also, serious impact appears in the energy feeding power system. Harmonics generated by electrified railway and negative sequence injected into three-phase power system result in more heating in rotation machinery, shortened lifetime of power transformer, higher capacity requirement of transmission line, multifunction of relay protection device and abnormal operation of safety automation equipment. Focusing on designing highly reliable high speed railway and meeting the limits of harmonics and power quality, this paper investigates the impact of high power electric machinery based CHR2 high speed train on the power grid. Various traction condition of the train is analysed by simulation, as well as the influence of different rectifier PI parameters on the power quality. The results of analysis and simulation is verified through a practical case study.

Abstract: With the economic globalization and knowledge-based increasingly grim today, more and more enterprises begin to use the team as a unit of work, the team becomes the indispensable one form of our work. How to get a higher team performance, it is one of the problems in today's scholars constantly explore. Existing research shows that team psychological safety can improve the performance of team, information sharing also affects the team performance in some way. From information sharing this new perspective, we combed the existing research both at home and abroad, then we establish the theoretical model of this study and put forward the hypothesis of this article. Through the empirical analysis, we discuss the relationship between team psychological safety and information sharing and team performance, and we verify the intermediary role of information sharing between team psychological safety and team performance. This study concludes that: team psychological safety can effectively predict the information sharing; information sharing can effectively predict team performance; team psychological safety can effectively predict team performance; information sharing plays an intermediary role between team psychological safety and team performance, but not completely mediation. Through this study, we can provide theoretical support for the team management, we can also provide constructive suggestions and referential countermeasures for the advance of team performance.

Abstract: The old industrial buildings have a remarkable culture, utilization and landscape value, re-use of old industrial buildings is a complex problem involving multiple interests and multiple theories. We should quickly establish eco-consciousness and the concept of re-use for turning the old industrial buildings to urban open space, cultural creativity and commercial office space, etc. Furthermore, the interior renovation of old industrial buildings should focus on the using of materials, lighting and landscape. Structure of old industrial buildings should be heritage for that should be utilized more reasonable under the using of new material and the improvement of design process.

Page No: 242-250

Abstract: Harmonic drive is a new driving method emerged with the development of space technology that utilizes the elastic deformation wave of a flexspline to achieve power transmission. The major failure mode of a harmonic drive is the fatigue wear of gear teeth in flexspline. In order to investigate the fatigue strength of flexspline during transmission, this paper designs a new contact fatigue testing system for harmonic drive to simulate the meshing process of flexspline and circular spline. The finite element model of the testing system is built by ABAQUS, and a dynamic simulation is conducted to analyze the stress distribution for critical positions of the model. The stress analysis results are compared with the simulation results of a simplified structure of harmonic drive.

Abstract: As well as the development of conventional gas fields, accurate analysis of shale gas dynamic and shale gas reservoir characteristics and forecasting capacity is the basis of the scientific development. The average open-flowcapacity is obtained by the multi-point back pressure method, and putting it into the empirical productivity formula to obtain the bottom hole flow pressure under different test gas systems. Getting the fitting of the horizontal well binomial deliverability equation under the condition of ideal gas reservoir with those already known. In the fitting formula, the daily production capacity of gas well is mainly related to the difference of production pressure and the length of horizontal section. After determining the length of the horizontal section and the average formation pressure, the shale gas production capacity prediction can be completed by using this formula.
