AI Technical Summary
Existing wind turbine vibration damping devices have poor damping effect due to uneven force distribution, and cannot effectively isolate the impact of vibration on the concrete foundation.
An adjustable damping shock absorber is adopted. By setting an adjustable damping unit and multiple adjustable damping components between the bases of the fan, the spring force of the damping spring is adjusted to make the shock absorber uniformly stressed and isolate vibration.
This ensures that the fan vibration value is within the allowable range, effectively isolating the impact of vibration on the concrete foundation and meeting the user's vibration isolation requirements.
