Software for Calculation of Rubber Springs

(C) Copyright 2003-2017 by HEXAGON Software, Berlin


Calculation of Rubber Springs

FED12 calculates characteristic line of spring (load-path diagram), pressure and deformation of cylindrical compression springs with and w/o bore, made from rubber or elastomere material. Material can be selected from integrated database. Load-path curve of rubber springs is progressive due to variation of pressure area and form factor at deformation process. Modulus of elasticity for elastomere materials depends on form factor. Form factor k is the ratio of pressure area to free deformation area. Under load, rubber spring deforms from cylindrical to barrel shape.

Material Database

The material database of FED12 provides material properties and parameters of modulus of elasticity as function of form factor for most essential elastomere materials. The user can add new materials to database.

Diagrams

FED12 calculates characteristic line of spring (load-path diagram) as function of spring travel and spring length. FED12 plots the curves of spring rate (spring load / spring travel) in dependance of spring travel, and modulus of elasticity as function of form factor k.

Quick-View

Quick-View provides spring drawing, load-path diagram, and a table with essential results on one screen.

Printout

Calculation results with spring loads, pressure and deformation data can be printed, saved as text or HTML file, or exported to MS-Excel.

Spring Drawing

FED12 generates a true-scale drawing of the rubber spring ready for export to CAD. Or set spring length between L0 and Ln, FED12 draws deformed rubber spring in barrel shape.

Production Drawing

FED12 generates a production drawing of the rubber spring, ready for printout.

.

Animation

Deformation of a rubber spring between two spring positions can be simulated on screen.
