Abstract: With the loss of the advantage of the demographic dividend, investment and cost of Chinese modern industrial life cycle will be subject to more attention, thus, modern streetcar security operations electrification, automation and digitization increasingly seem urgent importance. Based on the positive line in Jiangsu Province, Suzhou Modern Line 1 tram depot and project scheduling control center for digital applications electrification project, design of digital integrated intelligent integration of the key technology development programs. Breaking the big railway, subway semi-automated routine traditional design proposed digital, green, low-carbon technologies of the new design concept, creating a modern Chinese city tram electrification digital intelligence information systems security operation of a new design pattern.

Abstract: As one of the six thematic sessions on the topic of the “the Belt and Road International Cooperation Forum”, infrastructure connectivity with the theme of “Connectivity and Prosperity”, has cooperated with all sides to discuss transportation, energy and telecommunication in China. In the future, the global infrastructure upgrades and interoperability, transportation, energy and telecommunication technology integration development, will have new power to stimulate economic growth. In the construction of a new generation of infrastructure network system, the late-developing countries face a rare opportunity for leapfrog development, and the experience of China’s infrastructure development is of great significance.

Abstract: The main bridge of the Second Penang Bridge in Malaysia [1-2] is a two-pylon three-span prestressed concrete cable-stayed bridge, with span arrangement of (117.5+240+117.5) m.The pylons and the main girder are monolithic. The main girder, which is 34.6m wide, adopts the ladder type concrete deck section comprising top slab, transverse diaphragms and edge beams. The pylons are H-form pylons, and the stay cables are formed of parallel strands and are arranged in fan cable planes. Each pylon column carries 18 pairs of stay cables that are anchored by the deviation saddles in the pylons and anchor blisters in the main girder. The foundations consist of large diameter bored piles, varying from 2.3m to 2.0m in diameter. An optimized design scheme is tailored for the bridge, in which the main girder has the cross-section built up by a combination of slab, diaphragm and edge beam structuresand was constructed by using the rear supported form traveler and incorporating an optimization of construction timing. The scheme resolved the problems of load-bearing capacity verification for bridge deck and the verification of main girder prestress under the heavy vehicle loads prescribed in the BS5400. Meanwhile, a meticulous calculation method was put forward for the design and analysis of the main girder, to obtain the real load bearing conditions of the main girder and the bridge deck. The diaphragms were calculated by the spatial grillage analysis method, aimed at guaranteeing the load-bearing safety of the structure.

Abstract: The importance of the research about ship motion model has become more prominent with the improvement of economic level. Mastering ship motion model is a necessary basis for studying ship's divisibility. The hydrodynamic parameters obtained by parameter identification methods are more precise, which is dissimilar from the parameters obtained by classical methods. In this paper, a SWATH-USV was taken as the research object to accomplish a series of pitch decay tests on the condition that the SWATH-USV was in different drafts and tilts angles in the hydrostatic state. And a mathematical model by the method of system identification based on genetic algorithms has been established, adopting VB language to program a systematic identification software. With this, the author obtained the pitch motion differential equations, and the changing regularities of hydrodynamic coefficients with draft and initial tilt angle of the model in different drafts and initial tilt angles and their kinematic equation. Using this equation to predict, the results are proved to be well matched with the experimental results. And the feasibility of the identification method is also confirmed. The analysis results and methods can provide essential technical support for the in-depth analysis of the wave resistance and the design of the boat.
