摘要： The present disclosure is related to methods for determining a frequency of an oscillation mode of a wind turbine, comprising: determining a motion of a first mass of a first tuned mass damper in the wind turbine and deriving the frequency of the oscillation mode of the wind turbine at least partially based on the determined motion of the first mass. The present disclosure further relates to methods for operating a wind turbine, and to wind turbines, particularly offshore wind turbines, comprising tuned mass dampers.

摘要： The present disclosure provides a system for estimating tension in a post-tensioned rod, the system comprising an impact device for transversely-impacting a post-tensioned rod and being configured to determine a difference between a first and a second modal frequency corresponding to the vibrational response in the post-tensioned rod. Furthermore, the present disclosure provides a computing device and a non-transitory computer readable medium for determining a frequency difference between a first and a second modal frequency of a post-tensioned rod and a method for determining whether a frequency difference between a first and second modal frequency of a post-tensioned rod can be found.

摘要： The present invention provides a track bed resonator arranging method, characterized by comprising:
step S 1, conduct vibration test on the track line and inside the building at the sensitive point near the track line that is greatly affected by vibration as the train passes through to obtain vibration data;
step S2, calculate and determine the arranging range of the track bed resonators based on the vibration data measured in step S 1;
step S3, perform frequency domain analysis on the vibration data of the sensitive points to determine the indoor vibration resonance natural frequency of building at sensitive point affected by train passing;
step S4, design the track bed resonators based on the indoor vibration resonance natural frequency, so that the natural frequency of the track bed resonator is equal to the indoor vibration resonance natural frequency;
step S5, arrange the track bed resonators along the extension direction of the track line on the track bed within the arranging range.-
