摘要: Drag Detection is provided. A system includes one or more processors of a vehicle, coupled with memory. The one or more processors can determine, for a vehicle, rolling drag based on energy input to one or more motors of the vehicle and a speed of the vehicle. The one or more processors can select, based on the rolling drag and a friction level associated with a surface on which the vehicle traverses, a slip target for the vehicle. The one or more processors can provide the slip target to a traction control system of the vehicle to control the one or more motors.

摘要: A current collector for a non-track-bound, electrically driven vehicle for feeding electrical energy from a two-pole overhead line system with two contact wires. Two upper arms are rotatably connected to an adjustable lower arm by toggle joints. Each upper arm carries a contact rocker for contacting the contact wires. Coupling bars are rotatably connected to the upper arms and articulated so that adjustment of the lower arm forces adjustment of the upper arms. A compensating rocker compensates for a height difference between the contact rockers with a rocker stand and a rocker beam. The rocker stand can be rotatably connected to the vehicle and the rocker beam is connected to the coupling bars by way of compensating joints on either side of the rocker joint. At least one stop element limits a rotational movement of the rocker beam about a rocker joint axis of the rocker joint.

摘要: The present invention provides a graphene copper pantograph pan material for high-speed trains and a preparation method thereof, and the pan uses graphene as a reinforcing material, copper and iron as base materials, coke powder and graphite fiber as self-lubricating wear-resistant materials, and titanium, tungsten and molybdenum as additives. After being uniformly mixed, all the components are directly formed by hot pressing. The pantograph pan prepared by the present invention has the advantages of favorable electrical conductivity, wear resistance, impact resistance, ablation resistance and the like, and has little wear to overhead lines. The pan not only has simple preparation process, but also has much better performance than the conventional carbon pans and metal impregnated pans. The pan material is not only suitable for pantograph pans for high-speed trains such as high-speed rails and bullet trains, but also suitable for electric contact materials for low-speed trains such as subways.

摘要: A surface plasma actuator includes a conducting wire attached to a surface of a target object and electrically insulated from the target object. Surface plasma is generated along a neighborhood of the conducting wire by applying a pulse voltage between the conducting wire and a conductive portion on a side of the target object. An induced gas flow is generated by the surface plasma.

摘要: A monitoring system for an electric vehicle that draws current from a conductor is provided. The monitoring system includes a plurality of sensor modules distributed at spaced intervals throughout a conducting block of a current collector. The conducting block contacts the conductor in operation of the vehicle. Each sensor module comprises a strain sensor configured to output a first optical signal that reflects changes in strain and temperature of the conducting block and a strain-isolated temperature sensor that is configured to output a second optical signal that reflects changes in temperature of the conducting block. The monitoring system also includes an optical source for illuminating each sensor module and an optical signal interpretation module configured to receive first and second optical signals from each said sensor module. The optical signal interpretation module is configured to determine, from the optical signals, a temperature-independent strain measurement for each said sensor module.

摘要: A slider is slightly moved in a direction in which both side surfaces of the slider come in contact with inclined surfaces of impact mitigating parts of neighboring contact strip pieces. For this reason, the inclined surface of the impact mitigating part of the contact strip piece which the slider approaches is relatively downwardly slid with respect to one side surface of the slider. In addition, the inclined surface of the impact mitigating part of the contact strip piece from which the slider moves away is relatively upwardly slid with respect to the other side surface of the slider. As a result, since an impact generated between the contact strip piece and the slider is mitigated by the impact mitigating part without fitting the slider into a stepped section between the neighboring contact strip pieces, the slider is smoothly transferred from the one contact strip piece of the neighboring contact strip pieces to the other contact strip piece.
