Calculations are performed under the action of both constant and time-varying loads. The main ones are calculations for static strength under constant load and endurance under variable loading. Design and verification calculations are carried out by analytical methods of the strength of materials.
In more complex cases of loading and fastening, springs can be calculated by the finite element method, but for this you need to use other modules of the APM WinMachine system , such as APM Structure3D or APM Studio . With the help of these modules, it is possible to calculate the strength, stiffness, stability and dynamics of a spring under arbitrary loading and fastening.
