Research on the Engineering Application of Rail Vehicle Structural Health Monitoring System
With respect to the life cycle monitoring and intelligent operation and maintenance requirements of key structures of rail vehicles,this paper develops a structural health monitoring method and system that integrates fiber grating sensing and piezoelectric intelligent perception,uses fiber grating and piezoelectric sensing network to obtain key status information such as strain and damage during the service of the structure,realizes structural damage monitoring and safety assessment,and establishes a communication link with the ground operation and maintenance center to provide support data for the intelligent operation and maintenance of vehicles.It shows that the system can effectively meet the requirements of life cycle monitoring and intelligent operation and maintenance of rail vehicle structures.
