Extension spring design on a new Level
In the IGF research project 22762 BR (01/2023–09/2025), the team led by Prof. Kletzin at TU Ilmenau, together with the Association of the German Spring Industry (VDFI) and numerous member companies, developed new approaches and methods for extension spring design.
The objective was to determine both existing stresses that have so far not been calculable and previously unknown permissible stresses, and to consolidate these into strength verification calculations and diagrams.
