52031.项目总结报告：汽车废热回收热电技术的发展（2005.5.23——2011.10.31）
[汽车制造业] [2014-03-21]
We conducted a vehicle analysis to assess the feasibility of thermoelectric technology for waste heat recovery and conversion to useful electrical power and found that eliminating the 500 W of electrical power generated by the alternator corresponded to about a 7increase in fuel economy (FE) for a small car and about 6for a full size truck.We obtained critical vehicle level information for these driving cycles that enabled a highlevel design and performance analysis of radiator and exhaust gas thermoelectric subsystems for several potential vehicle platforms, and we identified the location and geometric envelopes of the radiator and exhaust gas thermoelectric subsystems.

52032.基于ANSYS的汽车后视镜振动模态分析和结构优化设计
[汽车制造业] [2014-03-21]
In this paper,we use the finite element software ANSYS to simulate the vibration frequency and vibration modals of the car rear-view mirror under the condition of excitation sources.Based on this and the strength analysis results of the rear-view mirror,we make a optimal design of the rear-view mirror structure.We get five-order vibration modals in working condition and analysis the size of displacement and deformation,and dynamic characteristics.The results show that because of the low modal frequency,the car rear-view mirror is easily inspired by the engine,powertrain system and road to vibrate.

52033.谁最可能购买PHEV：详细的市场细分分析
[汽车制造业] [2014-03-21]
The ORNL MA3T model developed for the U.S. Department of Energy is described and used to project PHEV purchase probabilities by different consumers.It is observed that consumers who have home charging, drive more frequently and live in urban area are more likely to buy a PHEV. Early adopters are projected to be more likely PHEV buyers in the early market, but the PHEV purchase probability by the late majority consumer can increase over time when PHEV gradually becomes a familiar product.

[汽车制造业] [2014-03-21]
The project is designed to modify an existing sensor-based traffic monitoring system so that it serves as a test bed to evaluate the retro-reflector, lighting, and paint treatments of an emergency vehicle to determine whether particular combinations produce improved 'move over' behavior of oncoming traffic.

52035.汽车氧传感器的新型电解质制备与离子导电机制
[汽车制造业] [2014-03-20]
The ionic conductive behavior of the electrolyte was analyzed on the basis of electrochemical impedance spectroscopy (EIS) test,and the interaction of working temperature,defect microstructure and ionic conductivity was investigated.Accordingly,the SDC displayed an ionic conductivity of 0.029 S cm-1 at 750 ℃.It was suggested that the nano-crystalline could shorten the transfer distance of the charge carriers.Furthermore,the structural change of the polycrystal boundaries with the temperature was a key factor which promoted the oxygen ionic conductivity.

52036.利用甲烷生产微波氢实验研究
[汽车制造业] [2014-03-20]
The results of this testing program have been very promising, demonstrating the ability to achieve higher methane conversion than onventional methane steam reforming processes. In addition to the higher conversion efficiencies, the microwave reactor system used for the process is more easily scaled to lower gas production volumes than conventional reforming technologies. This makes the technology well suited to generate hydrogen from natural gas for hydrogen fuel cells in the 1 to 20-kW range.

[汽车制造业] [2014-03-20]
The research content was limited to the effect of cutting parameters on the machined surface quality or cutting forces. It is suggested that high-speed milling with PCD tool should be conducted in order to improve the machined surface quality and material removal rate and decrease the machining cost. Tool life modeling, surface roughness prediction, cutting parameters optimization and high-speed milling data base and the expert system should be greatly noticed by the researchers.

52040.混合动力电动汽车功率分流模式分析
[汽车制造业] [2014-03-20]
EVT transmission in Planetary Gear Hybrid Electric Vehicles makes it available that the engine works on the optimal curves; yet because of the speed limitation of motor MG1,the maximum output power of the engine is a function of vehicle speed.The maximum traction and regenerative braking power is also a function of vehicle speed.Based on this,the vehicle drive modes consist of EV mode,economy mode and power mode,and braking modes include the regenerative braking mode and electromechanical braking mode.
