随着经济全球化趋势的持续升温,轮胎行业不可避免地受到冲击和挑战。国际化的竞争使轮胎产品的制造和销售不再单纯限于某一国家或地区,而是与全球轮胎生产技术的发展和市场供求直接相关,任何轮胎企业都无法孤立于外。在全球经济一体化的今天,我们从外资轮胎企业投资战略向并购重组这一变化不难发现,目前跨国轮胎公司在中国的战略变化和中国轮胎企业投资并购的新趋势。 相似文献

交通拥堵收费是解决道路拥堵问题的有效措施。假设使用小汽车到达拥挤收费区域边界的出行者可通过2种方式到达拥挤收费中心区:小汽车直达及停车换乘公共交通(P&R)。对于出行者甲(对小汽车出行需求偏刚性)、乙(对小汽车出行需求偏弹性),采用进化博弈的方法,建立效益矩阵,分析在不同政府定价条件下两者出行方式选择行为的演化模型。结果表明,政府交通拥堵收费对出行者出行方式选择行为的演化起着重要作用,不同的定价区间会使得出行方式向不同的稳定状态演变。分析各种定价区间下出行者出行方式选择行为。 相似文献

A bond graph model of a mountain bike and rider is created to develop baseline predictions for the performance of mountain bikes during large excursion maneuvers such as drops, jumps, crashes and rough terrain riding. The model assumes planar dynamics, a hard-tail (front suspension only) bicycle and a rider fixed to the bicycle. An algorithm is developed to allow tracking of a virtual tire-ground contact point for events that separate the wheels from the ground. This model would be most applicable to novice mountain bikers who maintain a nearly rigid relationship between their body and the bicycle as opposed to experienced riders who are versed in controlling the bicycle independent of the body. Simulations of a steep drop are performed for various initial conditions to qualitatively validate the predictions of the model. Results from this model are to be compared to experimental data and more complex models in later research, particularly models including a separate rider. The overarching goals of the research are to examine and understand the dynamics and control of interactions between a cyclist and mountain bike. Specific goals are to understand the improvement in performance afforded by an experienced rider, to hypothesize human control algorithms that allow riders to perform manoeuvres well and safely, to predict structural bike and body forces from these maneuvers and to quantify performance differences between hard-tail and full suspension bicycles. 相似文献

The objective of this research is to identify factors associated with crashes due to overcorrection or oversteering of vehicles. Crash data was collected from 2011 to 2013 for the State of North Carolina in the United States. Logistic regression modeling was used to analyze crash data because of the dichotomous nature of the dependent variable (overcorrection or oversteering). The crash involvement due to overcorrection or oversteering of a vehicle decreased as the age of the driver increased. Drivers are 2.22 times more likely to overcorrect or oversteer when ill, 3.44 times more likely to overcorrect or oversteer when under fatigue, and 1.61 times more likely to overcorrect or oversteer when fallen asleep compared to normal physical conditions. Overall, driver characteristics and speed limit tend to play a major role in overcorrection or oversteering of vehicles. Programs to reduce impaired driving might help in the reduction of overcorrection or oversteering related crash fatalities or injuries. Additionally, training and driver education programs focusing on identified factors associated with crashes due to overcorrection or oversteering of vehicles will benefit drivers on how to respond during emergency or panic situations. 相似文献
