As an important structure supporting wind turbines, wind turbine towers can reach a height of more than 100 meters and are extremely heavy, so the connections between the various parts of the tower rely on a large number of high-strength bolts. These bolts must not only bear the weight of the tower itself, but also the huge torque and vibration generated when the wind turbine is running.

Problem Analysis:
The main problems faced by wind power tower fasteners are: fatigue fracture caused by long-term alternating loads, performance degradation in corrosive environments, and the complexity of installation and maintenance.

Solution:

· Choose high-strength weathering steel bolts : This material has good corrosion resistance and high strength, suitable for harsh outdoor environments.

· Preload and anti-loosening technology : Use a hydraulic tensioner to apply preload to ensure that the bolts are tightly connected; use locking washers or thread lockers to prevent loosening.

· Corrosion protection : Hot-dip galvanizing or thermal spraying of bolts can extend their service life.

· Intelligent monitoring : Install stress sensors to monitor the stress status of bolts in real time, warn of potential problems in advance, and reduce downtime.
