Design and spring dimensions

Designing springs involve many sciences; the most important is metals, mechanics and strength theories. Also high knowledge of the application and its standards and specialities is important for an optimal spring design.

Spring dimensions can be calculated with a high degree of accuracy, using theoretical models. We use in-house developed software for all traditional spring types, and we use specially configured FEM software for complicated geometries. High speed shock loading and transient phenomena are areas which are important in some applications. Lesjöfors has prepared a manual which offers basic information about most common spring types and the theories used.

To be able to select stress levels and evaluate creep/relaxation and fatigue performance a high knowledge not only of metals but also about spring manufacturing technology is important. The effect of residual stresses and the control of these stresses are important.

Lesjöfors support customers with high knowledge about springs, spring materials and surface treatments.

With team work together with the customer also the knowledge about the application is added hence the customer spring design and spring dimensions can be optimized in the best way.
