2Fuel Consumption Potential of the Pushbelt CVT显示文摘The efforts to further reduce fuel consumption of vehicles equipped with a pushbelt type Continuously Variable Transmission(CVT) focus on different sources of loss.In this paper the magnitude of these losses and their potential for reduction is described.Inside the CVT,the variator,its control strategy and the hydraulic actuation circuit can be distinguished as the main potentials.A major opportunity is offered by a new control strategy that takes the actual slip between belt and pulley as the control parameter.The resulting decrease of clamping forces on the pushbelt leads to a reduction of variator and actuation losses.Further potential is found in the hydraulic actuation circuit by an improved tuning of the power supply to the actual power requirement.Outside the CVT additional potential is found in start-stop functionality as supported by measures inside the transmission.The paper describes the theoretical background as well as practical fuel savings of up to 5.5% that were obtained in tests on vehicle level.Slip control adds an inherent robustness to the operation of the pushbelt and opens up the fuel saving potential of the CVT thus reinforcing its position as the benchmark for the near future.Van der Sluis, Francis Van Dongen, Tom Van Spijk, Gert-Jan Van der Velde, Arie Van Heeswijk, Ad 2011重庆理工大学学报(自然科学)2011,25,7:5
3Understanding and managing the morphology of branches incising into sand-clay deposits in the Dutch Rhine Delta显示文摘在在荷兰的西南的部分的 Rhine-Meuse 三角洲,河分支的形态学高度依赖于心土的 erodibility。在 Haringvliet 河口的闭合以后被开始的侵蚀过程由一个水坝分叉(在 1970 ) ,引起了几个连接分支的一个强壮的切口。由于这个区域的地质的进化,心土的岩性学显示出大变化在高度 erodible 沙并且糟糕 erodible 泥炭和泥土层。这研究显示出地质的信息怎么能被用来创造心土的 erodibility 的 3D 地图,并且这个信息怎么能被用来扼要表示在为词法模拟的计算模型的心土。在区域与之间的沙补丁的本地切入糟糕, erodible 床原因深搜索洞,因此在河岸不稳定性(流动幻灯片) 和象丁提,码头,隧道,和管道那样的构造的损坏上增加风险。数学模型的各种各样的类型,从 1D (SOBEK )到 quasi-3D (Delft3D ) 被使用了学习河床和可能的管理选择的未来发展。这些途径的结果证明模型为心土 schematization 要求一条层簿记途径的包括,不一致的沉积部分(沙泥) ,潮汐并且河分泌物边界条件,和能力减小搬运当模特儿。为减少风险的河管理,河床的发展怎么能在大规模和小规模上被探讨,被显示出。例如,沉积喂和床的固定的使用能为大规模管理被建议,当监视时,当对超过的小规模的开发的反应预先规定干预层次,在侵蚀的开始的干预能被建议。Kees SLOFF(C.J.)
