Spring is made of metal material and thick plate or casting sheet into the truncated cone shape of cross section of the sealing ring type spring.
Spring factory introduction except saucer spring outside gas spring, rubber spring, emerged in the vortex coil spring, abrasive spring, stainless steel plate spring, gas spring, extension spring,
torsion spring, profiled spring memory alloy spring such as the new spring.
Spring is widely used in machinery and electronics industry of a vibration isolator, when spring force to cause a lot of ductile deformation, the mechanical work or mechanical energy is converted to deformation energy, and the deformation of the spring fade after uninstall and respond to their original state, the deformation can be converted to mechanical work or mechanical energy.
Spring at work often suffer the effect of variable load and impact load, so as to ensure that in the spring can be worked on for a long time, the raw materials must have high ductility and ultimate strength limit, the other should have enough ductility and plastic deformation, and its excellent adjustable qualitative reasoning, but the deformation of the spring is full of people don't want to see.
All raw materials are a feature, are in force from zero ascends slowly, at first is proportional to the size of the deformation and force for a period of time, then to gradually return to zero, the object appearance will be fixed, but when the power to do certain hours, will produce plastic deformation, deformation, the appearance design of the object will be a permanent change, while the force and deformation of the association is not direct proportion, and the people living a spring etc, all is to use this a direct ratio of the object, don't expect them to produce permanent deformation, so there is this term deformation category, category of deformation with raw materials of the object, the geometry of the object, the relevant temperature.
Spring deformation: spring in the specific application process, can prevent permanent deformation condition.
Even asked to select raw materials, applications shall not exceed the original working pressure or applied for.
Still can not prevent spring from the condition of deformation.
Therefore, the spring design must fully consider whether effective.
Enhance the level of processing technology.
In addition, there is also a way to reduce the problem of permanent deformation.
It is preloading.
In manufacturing, the deformation of the preloading index is calculated.
Preloading after deformation, and can design specification.
