Which spring steel wire is suitable for which application? Spring steel wire compared to other steels has a higher strength and can be up to a certain voltage ( Elastic limit “Rp” ) are deformed. With this property, the spring
The Goodman diagram enables the representation of the Fatigue strength of coil springs. It can be traced back to the Smith chart. This is used to calculate the fatigue strength of dynamically stressed components where the load is pulsating or
The modulus of elasticity is a material parameter from materials engineering and defines the slope of the graph in the stress-strain diagram. This characteristic describes the relationship between tension and strain in the deformation of a solid body in a
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
Here is an overview of the different eyelet shapes for Extension springs after DIN EN 13906-2: 2013 with the respective loop properties. Extension springs should only be subjected to static loads. If higher loads are planned, bent eyelets should be
In the first part of this two-part series Gutekunst Federn informed about the basics of spring design. In this second part you will find the concrete calculation data for the design of compression springs, extension springs and torsion springs (torsion
List of the most important spring steels with material description, operating temperature, modulus of elasticity (E-modulus) and sliding modulus (G-modulus) as well as price index. Compared to other steels, spring steel has a higher strength and can be deformed up
The term fatigue strength comes from materials science. It describes the deformation and failure behavior of an oscillating (dynamically) loaded material for a defined number of cycles. Especially at heavily used compression springs it is important to record the fatigue
The spring characteristic shows how the metal spring behaves at work. It describes the relationship between spring force ( F ) and spring deflection ( s ). Depending on the type of spring or the spring system used, a distinction
Today’s designers work exclusively with CAD programs. That reinforces the trend too Standard springs . The CAD data is already available here, the designers lose no time: Simply go to the provider’s website, download the data and import it into
