232.基于遗传算法的汽车动力传动系统多目标优化研究
[汽车制造业] [2014-03-24]
Simulation model of automobile power train has been built using ADVISOR,on the basis of Genetic Algorithm Tool Box,the paper takes a mini car as example to carry out performance simulation calculation and power train parametric optimization design.The result show that automobile power performance and fuel economy and emission performance have been greatly improved. It is an important approach to optimize its matching parameters on reducing the fuel wastage,improving dynamical performance and decreasing the emission of waste gas. It is a better approach to cope with automobile power train match optimization by integrating ADVISOR's accurate simulation with Genetic Algorithtn's searching optimization with high efficiency.

235.车辆碰撞相容性协议增强的评价：皮卡和SUV首要及次要能量吸收结构的有效性
[汽车制造业] [2014-03-21]
The Enhancing Vehicle-to-Vehicle Crash Compatibility Agreement (EVC) was established in 2003 as a voluntary measure to reduce occupant fatalities of passenger cars in crashes with light trucks and vans, including pickup trucks, SUVs, minivans, and full-size vans, generically abbreviated as LTVs.these results provide some evidence that the EVC has reduced fatalities but are not sufficiently strong to permit an unequivocal conclusion that it has been effective in reducing fatality risk to car occupants.

236.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.
