FED15 - Software for Leaf Springs
FED15 calculates simple leaf springs from rectangular flat spring material. Leaf spring can be fixed clamped or on two bearings, and loaded by only one axial force. The load introduction position must be at the spring end if fixed clamping, and in the middle of the spring if bedded on two bearings.
For complex leaf springs, loaded by various radial and axial forces, bending moments and path load, however, we provide another software: FED10.
Material Database
Material properties of the most important flat spring materials (tensile strength, permissible shear stress and bending stress as function of material thickness, modulus of elasticity, density) are stored at the integrated material database. The dbf file may be extended and modified by the user.
Pre-Dimensioning
FED15 also provides a pre-calculation. Enter one or two loads and deflection, and FED15 calculates dimensions of the leaf spring. Modify ratio of spring length to deflection and safety sigmaz/sigam2 to vary leaf spring dimensions.
Load-deflection diagram
FED15 calculates load-deflection line of the loaded leaf spring.
Goodman-Diagram
If dynamically loaded, Goodman diagram is useful to calculate fatigue strength safety and bearable load cycles of the spring.
Quick View
Load-deflection diagram together with tables of the essential spring data and results are printed on one page.
Printout
Input data and calculation results with spring travel, spring length, spring load and stresses for different spring positions may be printed, saved as text or HTML file, or exported to MS Excel via OLE interface.
Production Drawing
FED15 generates a production drawing of the leaf spring.
HEXAGON-Help System
Auxiliary text and images are available for all dialogue windows. If error messages occur, you can get description and remedy suggestion.
Interfaces
All drawings and diagrams can be saved as DXF or IGES file to be loaded with CAD programs.
The OLE interface lets you import/export data from/to Excel.
Export Formats
DXF, IGES, HTML, TXT, DBF, Excel, F15.
