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).
Abstract:
PURPOSE: A station guidance broadcasting system in a subway passenger room is provided to offer various information to passengers such as historical information related with a subway station. CONSTITUTION: A receiver(110) is included in a subway passenger room. The receiver receives reference information of a transmitter. A controller(120) is connected to the receiver.

Abstract:
PURPOSE: An aramid strip structure reinforcing method and a structure reinforcing member of an aramid strip, which prevents the deterioration of an aramid fibrous layer by a degradation prevention layer, are provided to improve earthquake resistance by using a PC steel wire. CONSTITUTION: An aramid strip structure reinforcing method is as follows. A plurality of steel wires(10) is wrapped with a plurality of aramid fibers. A resin bath(30) penetrates through a gap between the aramid fiber and the steel wire. The steel wire and aramid fiber are pressurized into the interval of guide plates in order to form a steel wire-embedded aramid fiber layer(40).
