Abstract: Mechanical lifting garage is designed to achieve a variety of vehicles parked automatically and scientific storage storage facilities. Because the traditional design need one drives for each plate, it waste energy and increase the cost. This paper introduces the course of development of the lifting garage, status and various types of three-dimensional garage features. Then it takes two floors with five parking spaces lifting garage as an example, describing the working principle, the mechanical analysis, the main connection point of framework, and the driveline design. The design innovative use "one drive for multi-plate", reasonable design to achieve the lifting of the garage and pan. In addition, in order to ensure the safety of vehicles and personnel of the design also incorporates the gantry fall protection and other safety devices.

Abstract: This paper carried out the control system design of a DFV based on dynamical characteristic analysis, and flight experiments were carried out to validate the performance of the control system. Firstly, the characteristics such as outstanding and control difficulty were pointed out, and then the control strategy such as three forms of translation is proposed. In the end, the controller was realized and tested by a series of experiments, and the excellent performance was demonstrated by the experimental results.

Abstract: In this article, using the method of the separation of cars and platform design to pressure balance work over rig, that is a large welded structure. Work platform components adopt link and structural member is h-section steel, in terms of stress at work is more complex. Through the 3D design software to model and to analyze the stress of the several typical working conditions, to verify the rationality of the design of the structure and put forward the improvement opinion. The analysis also can be widely applied in all kinds of integral welded structure.

Abstract: According to the hazard identification theory, run risks of solid rocket motor waterjet clearing system were identified from three different angles and potential causes of run risks were investigated; based on analysis of accidents that may occur in the running of solid rocket motor waterjet clearing system, fault tree analysis of propellant combustion/explosion and AP wastewater spill was carried out, minimal cut sets (path sets) and structural importance of each basic event were obtained, and furthermore corresponding recommendations in the accident prevention of solid rocket motor waterjet clearing system running were given accordingly.

Abstract: This article derives fuzzy profit models to value the wind power project. The performances of the proposed fuzzy profit models are verified by considering their application to a simulation case. The studied results are consistent with those provided by the conventional crisp models, and provide readily implemented possibility analysis tools for use in the arena of uncertain economics.

Abstract: Integrated transport hub as an important node of urban public transport system, in this paper, in accordance with the need of Integrated transport hub emergency management, based on the concept of public safety priority, the system composition and functional features to conduct a comprehensive analysis of the function, details of the integrated transport hub cooperative scheduling with the goal of building emergency command system, the system function structure, function modules of the logical relationship. The system research to establish integrated transport hub system scheduling and emergency command system has guiding significance and promotion value.
