Stability of locking screws in vibration environments

The design of locking screws includes a variety of locking mechanisms, such as locking washers, spring washers and self-locking threads. The combined effect of these mechanisms can provide additional locking force to prevent the screws from loosening when subjected to external vibration. Conventional threaded connections may loosen due to frequent vibrations, while locking screws effectively maintain the tightening state by increasing friction and resistance.
The use of locking washers can increase the contact area between the screw and the parent body, thereby increasing friction. Under high load or impact conditions, this increased contact area can effectively disperse the force applied to the connection and reduce the risk of loosening. The spring washers absorb vibrations through elastic deformation, further enhancing the stability of the connection.
The material selection of locking screws also directly affects their performance in vibration environments. Usually, these screws are made of high-strength steel or corrosion-resistant alloys with good fatigue resistance and durability. In harsh working conditions, such as high temperatures or corrosive environments, the fatigue resistance of these materials is particularly important because they can effectively resist fatigue damage caused by long-term vibration.
In practical applications, the stability of locking screws has been widely verified. In earthquake simulation tests and vibration experiments, connection components using locking screws have shown significant superiority and are able to maintain the integrity of the connection under dynamic loads. For example, locking screws are often used in earthquake-resistant designs in construction projects to ensure the safety and stability of the structure in bad situations such as earthquakes.
