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
Spring steel wires and their properties
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
Design spring body
Metal springs are used in various designs. In addition to the cylindrical design, which is most commonly used, there is also the conical, barrel-shaped design or for special ones dynamic Compression spring applications the beehive spring. Each design has a
Design of metal springs – Part 2 “Calculation
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
Fatigue strength
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
Spring characteristic
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
Spring work
In the spring work “ W “ becomes through when tensioning the spring Deformation work potential energy generated and stored, which is released again when the spring is released. The spring work always results as the area below the Spring
Information compression springs
Compression springs or coil springs are mechanical energy accumulators that absorb forces when they are compressed and release the forces when they are released. Gutekunst Federn offers quick selection and procurement of compression springs in its catalog program on Federnshop.com
