1591.改善轮轨接触状态的重载车轮型面优化研究
[铁路、船舶、航空航天和其他运输设备制造业] [2015-04-03]
基于轮轨接触几何关系,以轮径差函数为设计目标,对重载线路75kg/m钢轨型面进行逆向求解,优化出满足轮径差函数的重载车轮型面;对优化前后重载车轮踏面的静态接触、动力学性能和基于磨耗数的车轮损伤函数进行了对比。结果表明:优化后重载车轮踏面与75kg/m钢轨匹配时,轮轨间接触点分布更加合理,接触斑最大正压力有所降低,具有更好的曲线通过性能;优化后的车轮踏面在高低轨呈现出更小的损伤值,可有效降低轮轨磨耗与裂纹损伤。

1592.基于Petri网列车群模型的列车运行冲突分析
[铁路、船舶、航空航天和其他运输设备制造业] [2015-04-03]
列车运行冲突检测是铁路系统安全运营的重要保障。本文首先给出赋时着色Petri网的形式化定义,定义变迁使能和触发规则及状态转移函数;基于赋时着色Petri网,以库表示车站/闭塞分区,托肯表示列车,建立列车群模型,为冲突检测提供模型基础。在经典Petri网冲突定理的基础上,结合库容量约束和时间间隔约束,提出列车运行冲突判定定理,并证明该方法的正确性;在此基础上,设计基于可达树的冲突分析方法,并以太原铁路局部分线路为例,通过实例介绍列车运行冲突和进路冲突检测分析的方法。基于Petri网的列车群模型为铁路系统冲突分析问题的处理提供新的途径。

[计算机、通信和其他电子设备制造业,铁路、船舶、航空航天和其他运输设备制造业] [2015-03-28]
Telemetry allows remote measurement and reporting of information and data. This can be through wired mode (telephone networks and optical links) or wireless mechanisms (radio, infrared, and ultrasonic waves). For aerospace and defense applications, it is generally the transmission of information from space (satellites, spacecraft) or defense systems to a ground control station on Earth or remote space vehicles with transmitting and receiving systems.
