摘要
提出了一种基于径向基神经网络、有限元分析和蒙特卡罗(Monte CarloMethod)数值模拟相结合的铁路接触网系统可靠度的计算和可靠性分析,建立了接触网系统可靠度计算的数学模型和神经网络模型.用此方法计算出了接触网接头线夹的可靠度并就外部参数的变化对可靠性影响进行了评价,该方法精度高、简便易行,为复杂的铁路系统可靠性设计和研究提供了一条新的途径.
Calculation and Analysis of reliability based on radial basis neural networks and Analysis of finite element combined with Monte Carlo numerical simulation is presented, Mathematic model of reliability calculation on eatenary system and networks model are established. reliability of eatenary tie-in clamp is calculated by the method and it is evaluated that variety of exterior parameter has an effect on reliability, the method is feasible and effective, It provides a new way for the design and research of reliability in complex system of railway.
