Abstract: In this paper, according to actual power demands of the bus, its powertrain was designed. In this process, the lowest oil consumption was the goal on the foundation of meeting basic power need. The co-simulation with Plug-in vehicle model was realized in Cruise, using the control strategy model which was established by the Stateflow in Simulink. Simulation results indicated that modified Plug-in hybrid electric bus not only can reach the expectant power indictors, but also improve the fuel economy. So, this research played a leading role in the design and research of hybrid buses’ parameters

Abstract: This paper is quoted from empirical equation of accumulating icing by sea sprays to analyze its sport mode and calculate the accumulation amount and distribution of 80000 DWT bulk carriers. It also analyzes the effect of sea spray and icing to the ship structure in ice zone, which reinforces to know the danger of icing. Therefore, this paper has a significant influence and reference value for evaluating the hull strength of ice zone going ships.

Abstract: Improving airspace and runway utilization is the key to reducing flight delays with the rapid development of the air transport industry. Current flight separation standards generally take excessive interval margin, resulting in unnecessary waste of airspace resources and runway resources. Wake accidents still happended even with strictly wake separation standards compliance, which is mainly due to the imperfect separation standards affected by the wake complexity and modeling imperfections. Refering to Chinese and international main wake models, we propose to improve the existing wake standard, usage of modern wake separation systems and dynamic wake detection strategy with automated judgment method. Purpose is reducing flight delays and improving the utilization of the airspace and runway on the basis of keeping safety.

Abstract: The aircraft deicing process is discussed to establish the airlines cooperative game model. The characteristic function and the core of the airlines coalition game model are analyzed, and then the solution of the model is proposed based on Shapley value. Finally, the result of the simulation shows that the cooperative game model motivates the cooperative action. The algorithm based on the Shapley value can meet both individual rationality and collectivity rationality. The results show the distribution is more reasonable and better.

Abstract: As the example of Leveling and lifting Electric Liquid Servo System of Tamp train, the mathematical model of system is established, dynamic characteristics are simulated and analyzed，parameters are corrected by means of MATLAB software, simulation effect has proved that servo system became reliable and stable.

Abstract: The composite trimaran is characterized by adding the hydrofoils with different aspect ration in the main hull and sides of the conventional trimaran hull. Regarding the programmable automatic controller as the core, the paper designed the unmanned intelligent control system of the composite trimaran ship model, used VB.NET language to design the maneuverability simulation platform on MMG. And designed six rudder blades with different aspect ratio, and carried out a series of manipulation turning tests of the ship model under different speed and rudder angle. Through comparing with experimental data and the simulation results, it has verified the reliability of the simulation platform. Then with the system identification methods, the paper has discussed the aspect ratio of the rudder which has influence on the manipulation rotary motion of the composite trimaran ship model, and the manipulation rotary performance of the composite trimaran ship model in different speed and rudder angle.

Abstract: This research focuses on the effect manufacture factors about the brightness and uniformity of multi-stage reflector. Trace-pro and 3D CAD model were used for optical simulations. The optical simulation results of grating lens and reflector were done as well as successfully developed the LED fog lamp. The results meet the regulations, R19 CLASS F3, of Economic Commission for Europe (ECE) at the test distance of 25 meters, and central zone under line6 achieves average over 3200cd. The optimal design of reflector is of third-order paraboloidal one to improve the brightness and uniformity. The acuter the microstructure’s tip is(R below 0.1mm), the better the apparent improving of eliminating stray light. In accordance with microstructure of grating lens, Moldex-3D is used to help the mold flow filling simulation and mold design. The mold cavity with microstructure was manufactured by the wire cutting and polishing processing. And the molding plastic was optics level PC (Polycarbonate). Both Taguchi’s method applied in Moldex-3D and real injection molding experiments showed that high melt temperature, low injection speed and suitable holding time can reduce warpage; in addition, using higher melt temperature, mold temperature and injection pressure can achieve higher degree of replication of micro features.

Abstract: In Taiwan, 3% ethanol (E3) blending fuel was introduced to the market to lessen the pressure of energy deficit and carbon reduction from global warming. This study is aimed at discovering the environmental impacts of exhaust emissions imposed by ethanol blending fuels. The tested fuels are 0%, 5%, 10%, 15% and 20% of ethanol blending, and engine testing set rotation speeds at 1500, 2500 and 3500 rpm to simulate slow, normal and fast speeds of vehicle driving. Gaseous emissions from engine exhaust were collected to determine the concentrations of CO, NOx, HC, BTEX, formaldehyde and acetaldehyde. Ethanol blending fuels were found able to reduce the emission of regulated air pollutants (CO, NOx and HC) and containing toxic compounds (BTEX) more or less. However, formaldehyde and acetaldehyde emissions were greatly enhanced due to ethanol combustion in the engine. With the use of ethanol blending fuels, the environmental impact on the release of formaldehyde should be aware and carefully controlled.

Abstract: Basing on the status quo of the development of electric vehicle and electric vehicle’s Charging/battery swap infrastructure, Discussion and analysis is made with focus on the battery swap mode and it’s practising method of electric passenger car. According to the body structure of different types of electric passenger car and the Situation that the battery pack is equipped with, Electric passenger car are divided into two types: chassis battery type and battery rear-equipped type. Respectively, analyzed the battery swap mode for the two types of electric passenger cars; And two feasible battery swap projects are advanced , analysed and compared.Then pointed out the difficulties and problems with the construction of the battery swap station for electric passenger car; Finally, suggestions and methods to solve the problems were offered.

Abstract: Obtained requirements by analysis of the business functions of the electric vehicle operations management to form four types of applications, and then design the physical architecture and logical architecture of electric vehicle operations management system(EVOMS), adopted the three level management system, fully construct operation monitoring system of support electric vehicle smart charging and battery swapping service network.
