It is the most widely used in almost all fields of activity. It is intended to undergo compression deformation. Helical in shape, there are different types : conical, biconical, variable pitch, constant pitch springs...
In the manufacture of compression springs, many parameters are taken into account. Its characteristics will depend on its use and the environment in which it will be used. The wire diameter, inner and outer diameter, number of turns, pitch and other parameters are essential elements for the part to produce a clean and high-quality movement.
When a machine is equipped with springs, they can be used for several purposes :
IIt works on a longitudinal axis. When the diameter is constant, the spring provides constant stiffness. For every additional mm of compression it passes, it delivers the same amount of additional force. When the diameter is variable, it offers a parabolic stiffness, almost exponential.
Thanks to its elastic deformation, it compresses until the coils are fully joined. It then returns to its original shape thanks to the return of the force acquired during its run.
|Kinetic energy||When a mass exerts a force on the spring, it is reduced in volume by compression. When it returns to its natural position, the mass gains speed and is projected further than the end of the spring. This energy is created by movement when it works, this is called kinetic energy.|
|Potential energy||It is the work performed by force that allowed the compression. That is to say, the potential energy is negative when it is in compression work. The energy is positive when the compression spring returns to its natural position because it gives way to its energy. It can be seen that this potential energy is zero when the spring is not compressed.|
Each type of spring operates on the same principles. However, the use varies depending on whether they are tension, torsion or flat springs.
