Abstract: Signaling system is the core equipment of railway operation safety guarantee. How to evaluate and improve the reliability of signaling system hardware equipment is an important guarantee to realize the reliable operation of railway signaling system. This paper introduces the multi-dimensional reliability simulation analysis method used in the phases of hardware products schematic design, PCB design, board design and whole machine design, and provides abundant simulation cases. The reliability simulation analysis is carried out from multiple dimensions such as circuit design, signaling integrity, failure physics and environmental stress simulation of the whole machine, so as to provide basis for hardware design optimization of signaling system and effectively improve the reliability and safety of equipment.
