After determining the spring dimensions, the Proof of strength be guided. For this purpose, the existing shear stress is determined. Shear stress for compression springs Shear stress compression spring from force: Shear stress Compression spring from displacement:
Exceeds when the spring is loaded Shear stress the permissible value, a permanent deformation occurs, which manifests itself in the reduction of the unstressed length “L0”. This process is called “setting” in spring technology, which is associated with the properties
Every spring design of a compression spring consists of two stages : 1. The proof of function, with the verification of the dimensions, spring rate, forces, spring travel and vibration behavior. 2. The proof of strength, with the verification of
Description Formula symbol tension springs Before interpreting the extension spring it must be clarified whether the intended type of stress is a static or a dynamic stress acts. No general fatigue strength values can be given for dynamic loads on
