51863.并联式混合动力电动汽车动力总成系统的匹配与优化
[汽车制造业] [2014-09-03]
The parameters matching of the hybrid powertrain system of the hybrid electric vehicle has a directly impact on the performance of the vehicle dynamic and the fuel economy.The preliminary match of the powertrain system base on analysis of Driving Cycle is done,then the software of AVL-Cruise and Matlab are integrated with Isight to optimize parameters of match,by using the Multi-Island GA and NLPQL to establish the combinatorial optimization algorithm.The results show that the fuel economy have been improved by 10.92% without sacrificing the dynamic performance and under the premise of ensuring the limits of the state of charge of battery.

51864.THOR-NTATD与HybridIIIATD在实验室的垂直冲击试验比较分析
[汽车制造业] [2014-09-03]
The Hybrid III dummy is a common standard test device for automotive car crash and mine blast (shock) events, which is validated and accepted by the crash test community. The Hybrid III 50th percentile male Anthropomorphic Test Device is also required by STANAG 4569 for injury assessment for mine detonation tests. The Test Device for Human Occupant Restraint (THOR) 50th percentile male advanced crash dummy is a next generation anthropomorphic test device that incorporates significantly improved biofidelity in all major parts and has expanded injury assessment capabilities beyond its predecessors, including the Hybrid III Anthropomorphic Test Device. Comparative evaluation of THOR versus Hybrid III dummies will bring additional insight and understanding of THOR injury prediction capabilities and biofidelity, specifically for vertical shock and mine blast events.

51867.最终报告:计算机辅助工程技术和先进计算机应用的设计,合作研究和开发

Oshkosh Corporation (OSK) is taking an aggressive approach to implementing advanced technologies, including hybrid electric vehicle (HEV) technology, throughout their commercial and military product lines. These technologies have important implications for OSK's commercial and military customers, including fleet fuel efficiency, quiet operational modes, additional on-board electric capabilities, and lower thermal signature operation. However, technical challenges exist with selecting the optimal HEV components and design to work within the performance and packaging constraints of specific vehicle applications. OSK desires to use unique expertise developed at the Department of Energy's (DOE) National Renewable Energy Laboratory (NREL), including HEV modeling and simulation. These tools will be used to overcome technical hurdles to implementing advanced heavy vehicle technology that meet performance requirements while improving fuel efficiency.

51868.中期报告:电动汽车部署克服障碍的方法
[汽车制造业] [2014-09-03]
This report focuses on the light-duty vehicle sector in the United States and restricts its discussion of electric vehicles to plug-in electric vehicles (PEVs), which include battery electric vehicles (BEVs)1 and plug-in hybrid electric vehicles (PHEVs). The common feature of these vehicles is that their batteries are charged by being plugged into the electric grid. BEVs differ from PHEVs because they operate solely on electricity stored in a battery (that is, there is no other power source); PHEVs have internal combustion engines that can supplement the electric power train. The electric vehicle offers many promisesincreasing U.S. energy security by reducing petroleum dependence, contributing to climate-change initiatives by decreasing greenhouse gas (GHG) emissions, stimulating long-term economic growth through the development of new technologies and industries, and improving public health by improving local air quality. There are, however, substantial technical, social, and economic barriers to widespread adoption of electric vehicles, including vehicle cost, small driving range, long charging times, and the need for a charging infrastructure. In addition, people are unfamiliar with electric vehicles, are uncertain about their costs and benefits, and have diverse needs that current electric vehicles might not meet. Although a person might derive some personal benefits from ownership, the costs of achieving the social benefits, such as reduced GHG emissions, are borne largely by the people who purchase the vehicles. Given the recognized barriers to electric-vehicle adoption, Congress asked the Department of Energy (DOE) to commission a study by the National Academies to address market barriers that are slowing the purchase of electric vehicles and hindering the deployment of supporting infrastructure.
