    • PURPOSE: A reliability calculating method of a railway vehicle using a simulation scheme is provided to effectively calculate the reliability of the railway vehicle by using a Monte Carle simulation scheme. CONSTITUTION: The reliability relation of a system of a railway vehicle and a subassembly are comprised of an RBD(Reliability Block Diagram)(S110). The RBD is expressed as reliability route matrix(S120) by using adjacent matrix which directly shows the connection relation of spaces. The reliability route matrix is unfolded(S130). Whether the trouble about all subassemblies comprising the system is or not is expressed by using a Monte Carlo simulation scheme(S140). System reliability is calculated through whether the trouble about the subassembly is or not(S150).
    • 目的:提供一种使用模拟方案的铁路车辆的可靠性计算方法,以通过使用蒙特卡勒模拟方案有效地计算铁路车辆的可靠性。 构成:铁路车辆和子组件系统的可靠性关系由RBD(可靠性框图)(S110)组成。 RBD通过使用直接显示空间连接关系的相邻矩阵表示为可靠性路由矩阵(S120)。 可靠性路由矩阵展开(S130)。 包括系统的所有子组件的故障是否通过使用蒙特卡洛模拟方案(S140)来表示。 系统的可靠性是否与组件的故障有关(S150)来计算。
