52234.全球农业轮胎市场报告（2014-2018年）
[橡胶和塑料制品业,汽车制造业] [2014-03-24]
Tires are an integral component of automobiles and are manufactured using raw materials such as natural rubber, nylon tire cord fabric, and carbon black. Rubber chemicals and synthetic rubber, including styrene-butadiene rubber and poly-butadiene rubber, are also used in manufacturing tires. Agriculture tires are used in different agriculture vehicles and equipment such as tractors, sowers, and harvesters. The use of advanced equipment has had a significant improvement on crop yield and hence, is leading to cultivators and farmers increasingly using agriculture vehicles and equipment.

52237.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.
