1561.空气弹簧非线性横向特性的有限元计算
[铁路、船舶、航空航天和其他运输设备制造业] [2015-04-03]
根据超弹性材料的非线性本构关系,考虑空气弹簧的材料非线性、几何非线性和接触非线性问题,应用MSC.Marc软件建立了空气弹簧的有限元模型,以计算空气弹簧横向载荷与横向位移响应特性,得到其非线性横向刚度曲线,并通过实测数据验证了这一计算的合理性。并据此研究了内压、帘线角、帘线层数、帘布线厚度等空气弹簧参数对横向刚度的影响,以及帘线角对胶囊各铺层应力的影响,为空气弹簧的优化设计和横向特性分析提供了新思路。

1562.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。
