摘要：
Rotor blade monitoring of wind turbines. This work describes the development of a structural health monitoring system (SHM) which monitors the condition of rotor blades of wind turbines, and detects and locates structural Changes before final failure. It is based on a combination of measuring techniques with guided waves in the ultrasound range and low frequency modal analysis. The combination of both techniques has been applied promisingly in rotor blade investigations so far. Modal analysis allows for statements regarding the structural behaviour of the rotor blade structure. Areas of higher risk and stress are additionally monitored by guided waves in the ultrasound range.
