Electric cars – and their continued sales growth – are expected to have a greener, cleaner influence on air pollution and reduce human mortality in most, if not all, U.S. metropolitan areas, according...
Today’s car navigation systems provide driving instructions in the form of maps, pictograms, and spoken language. However, they are so far not able to support landmark-based navigation, which is the ...
It may be a while yet before we have cars that drive themselves, but in the near future your car may help you drive. In particular, it could warn you when you’re about to do something stupid.Cornell r...
Car drivers’ perceptions of the quality of alternative travel modes have been identified as a barrier for including these alternatives in their choice sets. The present study investigated the accuracy...
One of the main objectives for a rail company is to minimize the size of rail freight car fleet in order to reduce operating costs. The problem of rail freight car fleet composition is aimed at determ...
利用虚拟样机技术和动力学分析软件ADAMS/Car,建立了汽车整车动力学模型,并在Matlab/Simulink环 境下建立了ABS的控制模型。联合仿真结果表明:ABS联合仿真模型具有较高的可行性与有效性。该联合仿真 模型的建立可为加速ABS的研究和开发提供便利和基础。
According to the traditional approach, when estimating changes in transportation policies, the household income level (in all its forms) is perceived as the proper explanatory variable for modeling ...
This paper considers car allocation choice behaviour in car-deficient households explicitly in the context of an activity-scheduling process, focusing on work activities. A decision tree induction met...
This paper aims to provide insights that help transport academics and policy makers appreciate the potentials and limitations of information provision as a means to changing car-drivers’ travel choice...
Several researchers have proposed that drivers do not just respond to the vehicle directly ahead, but also to the second, and even the third, fourth or fifth vehicle ahead. Little empiri-cal evidence ...
According to gerontological mobility research, appropriate settlement structures at the neighbourhood level and car availability are both playing a prominent role in the maintenance of mobility of eld...
利用互易性原理,提出了一种空气声传播路径实验方法。首先测得各声源对于车内噪声的传递函数,进而得到各声源对于车内噪声的贡献度。根据声源识别结果,对汽车车身进行吸声、隔声设计,结果表明,车内地板隔声量从前向后分别提高了1.83~9.74 dB(A),汽车车内噪声下降了4.7 dB(A)。
The paper presents a theory of body collision with pit corner. The theory can be successfully applied in approaching tasks coping with the orientation of details in technological processes and control...
本项目主要研究内容为:完成并逐步完善了W-Car和GL-8、S-Car白车身检测数据集成系统软件,软件已经在金桥车身车间和王港车身车间正常运行,发挥其作用;完成了小样本采样条件下对检测数据进行分离处理和分析,并进行质量评价的正确性的理论验证和实际验证;对白车身焊装质量评价指标的合理性进行了分析、研究,拟定了白车身PASSRATE分析控制流程、白车身焊装质量控制流程、尺寸偏差诊断流程以及基于PMF的...
该产品主要起到连接汽车的发动机和散热器、加热器的作用。项目在橡胶材料配方设计中,选择了由美国埃克森公司生产Vistalon7500牌号的EPDM生胶作为橡胶主体材料;纤维采用美国杜邦公司Kevlar高强度纤维。在选择硫化体系、防护体系及增塑体系等等方面,则是采用高温低变形的硫化体系—过氧化物体系作为硫化体系,并选用分子量大、闪点高的增塑剂以增强耐热性能。
