煤矿斜井无轨辅助运输车辆在长距离下坡工况中存在大量的制动能量可供回收,受限于脚踏阀-本安电位计复合型制动踏板的并行结构,传统防爆型电动车辆多采用的机械-再生并行制动控制策略对制动能量的回收程度有限。为此,针对矿山无轨辅助运输电动车辆,提出了一种集成至加速踏板中的再生制动控制策略,以进一步提高再生制动能量回收率,有效增加矿井无轨辅助运输电动车辆的续航能力。基于车辆制动动力学和能量守恒定律,对再生制动过程进行了理论建模。结合辅运电动车辆驱动系统及加速踏板结构特征,建立了加速踏板集成型再生制动控制策略模型,并对车辆加速、滑行及制动过程中控制策略的工作原理依次进行了分析。根据国内某斜井煤矿辅运大巷人车转场运输作业载荷特征,制定了包含车速、坡道2因素在内的循环测试工况,以此为输入条件在Matlab/Simulink数值计算平台上对加速踏板集成型再生制动与制动踏板液压-再生并行制动2种控制策略进行了仿真对比分析,并在双滚筒转鼓式底盘测功机上对加速踏板集成型再生制动控制策略的仿真计算结果进行了实验验证。实验结果表明,加速踏板集成再生制动控制模型总电耗比原系统减少21.06%,等效工况续驶里程延长23 km,仿真与台架测试结果误差不超过5%,具有更好的能耗经济性。

Pb-free Sn-based perovskite solar cells(PSCs) have recently made inspiring progress, and power conversion efficiency(PCE) of 14.8% has been achieved. However, due to the energy-level mismatch and poor interfacial contact between commonly used hole transport layer(i.e., poly(3,4-ethylenedioxythio phene):poly(styrene sulfonate), PEDOT:PSS) and FASnI_(3) film, it is still challenging to effectively extract holes at the interface. Owing to the p-type nature of Sn-based perovskites, the efficient hole extraction is of particular significance to improve the PCE of their solar cells. In this work, for the first time, the role of chiral cations, a-methylbenzylamine(S-/R-/rac-MBA), in promoting hole transportation of FASnI_(3)-based PSCs is demonstrated. The introduction of MBAs is found to form 2D/3D film with lowdimensional structures locating at PEDOT:PSS/FASnI_(3) interface, which facilitates the energy level alignment and efficient charge transfer at the interface. Importantly, chiral-induced spin selectivity(CISS)effect of R-MBA_(2)SnI_(4)induced by chiral R-MBA cation is found to further assist the specific interfacial transport of accumulated holes. As a result, R-MBA-based PSCs achieve decent PCE of 10.73% with much suppressed hysteresis and enhanced device stability. This work opens up a new strategy to efficiently promote the interfacial extraction of accumulated charges in working PSCs.

双电机双轴驱动(front and rear axle independent drive,FRID)可以解决煤矿无轨辅助运输重型车辆排布困难和动力不足等问题,但该结构方式的驱动、制动性能的提升受到转矩分配策略的约束,如何实现双电机转矩协调控制是研究该类问题的重点和难点。针对矿用FRID铰接车辆的驱动转矩分配问题,为提高系统的能耗经济性,提出了一种基于门限的转矩分配策略,以车辆侧向操纵稳定性为约束条件,对门限分配转矩进行了限制,提高了车辆转弯时轮胎的侧偏刚度和侧向动力学性能;为确保车辆在低附着路面上获得最佳驱动力,以轮胎滑转率为控制目标对前后轴电机驱动转矩进行独立控制。在MATLAB/SIMULINK环境下分别建立了矿用双电机双轴驱动铰接车辆转矩分配控制器模型及车辆动力学模型,对不同路面条件下的控制效果进行了仿真分析。基于dSPACE平台,搭建了硬件在环仿真测试系统,对转矩分配控制器的实时控制性能进行了验证。结果表明:硬件在环测试结果与软件仿真结果具有良好的一致性,门限型转矩分配策略是一种简洁有效的经济型转矩分配策略,给定工况下的循环能耗比动力型分配可降低3%~5%;以侧向操纵稳定性为约束条件对门限分配转矩进行限制,内侧车轮的最大滑转率控制在0.2附近,提高了转弯时轮胎的侧偏刚度,从而降低车辆不足转向量,改善了车辆的转向能力。
