51601.动力吸振器在轿车低频轰鸣声控制中的应用
[汽车制造业] [2015-01-15]
针对某试验车后排右侧乘员处低频轰鸣声的特性及传递路径灵敏度进行了分析,确定发动机的2阶振动是该低频轰鸣声的主要贡献,是通过发动机的后悬置点传递到车身而引起的。提出了安装动力吸振器来减小发动机后悬置点处对振动传递的方法,并通过锤击试验和整车道路模拟试验表明,在该车前副车架后悬置点处安装动力吸振器,能够有效抑制其发动机转速为2 040 r/min时后排产生的低频轰鸣声。

51603.基于扩展卡尔曼滤波的轮毂电机驱动电动汽车状态估计
[汽车制造业] [2015-01-15]
以非线性八自由度车辆模型为基础,利用轮毂电机驱动电动汽车四轮转矩容易获得的独特优势,将车轮转角、各个车轮驱动力矩、侧向加速度及横摆角速度作为算法输入,采用扩展卡尔曼滤波(Extended Kalman Filter,EKF)理论设计了轮毂电机驱动电动汽车行驶中状态估计算法。CarSim和Matlab/Simulink联合仿真结果表明,该算法能有效估计轮毂电机驱动电动汽车行驶中的纵向车速、侧倾角、侧倾角速度等状态。

51606.全球高尔夫球车市场报告（2015-2019年）
[专用设备制造业,文化、体育和娱乐业,汽车制造业] [2015-01-12]
Golf carts are used by golfers to carry heavy golf clubs and equipment. They are also used for daily commuting needs over short distances. Golf carts are usually gasoline-powered or electric, but recently solar-powered golf carts have also been developed. Electric golf carts have more preference among consumers. The global economic recession of 2008-2009 had a negative impact on golf, which subsequently impacted the Golf Cart and Golf Equipment market worldwide. The economic recession impacted consumer preference due to financial instability and, hence, participation in golf declined. Since the economic recession, a subtle change has been observed in consumers' choices, and there is renewed interest in golf. Golf has become an important sport even in the emerging economies such as China and India. The inclusion of golf in the 2016 Olympics, which will be held in Brazil, is expected to positively drive the growth of the Global Golf Cart market.

Electric vehicles are gaining importance because of the rising global fuel prices and the alarming levels of air pollution. There is widespread concern over the negative effects of global warming. In such a scenario, the rapid adoption of electric vehicles is seen as the most viable solution. Earlier, the time taken to charge electric vehicles was one of the major concerns, but with the advent of wireless inductive charging, this issue has been resolved. Inductive wireless charging is considered as a major breakthrough because it has made the use of plugs and cords redundant. Inductive charging takes place when an electromagnetic field transfers energy between two coils.
