The spring is not in place and the cause of failure
In practical work, we often encounter that the spring cannot push the moving object to the set position, which means that the calculated free length of the spring is shortened. The main reason is that there is no initial compression treatment, that is, a manufactured spring is compressed to its compression height or tightening height (if necessary) with a large force, and it cannot be restored to its original state after being released. of free-length operations. The amount of shortening is called "initial compression". Generally, after 3-6 repetitions of compression, the length is no longer shortened, that is, the spring is "positioned". The spring is permanently deformed after initial compression.
