Research on the Degradation Process Analysis of the Rail Transit Door System

摘要

The door system is one of the important components of the rail transit, which is critical to the safety of both vehicles and passengers. It is necessary to monitor the degradation process of the door system and implement the maintenance before the failure occurs. However, there is few research on the degradation state analysis of the door system. In this paper, an accelerated life test platform is built for the rail transit door system, and the multiple sensors data of the whole life cycle can be obtained. The key features of the sensor data are extracted and selected. The degradation model of the door system is established by using the Support Vector Machine and the multiple linear regression. The feasibility and effectiveness of the proposed method is verified by experiments.
