Software for Calculation of Torsion Bars

(C) Copyright 1996-2017 by HEXAGON, Berlin


Calculation

FED8 calculates displacement angle, torques, shearing stress, spring operation and sliding for torsion bars in accordance with DIN 2091. Characteristic curves and scale drawings can be displayed graphically and exported as DXF files to CAD and text programs. Torsion bars of rectangular or elliptic profile may also be calculated by FED8.

Pre-dimensioning

In pre-dimensioning, one torque and the displacement angle are entered, or two torques and the elevation angle are entered. FED8 then calculates an appropriate torsion bar.

Dimensioning

In dimensioning, FED8 calculates the length of the torsion bar from the torque, elevation angle and bar diameter.

Re-calculation

In re-calculation, all dimensions for the torsion bar are entered. Loads and shearing stress for different displacement angles are calculated.

Printout

The result printout incudes all input and result data. The excerpt shows the most important spring data, abbreviated, on one page. There is also a feature for output as HTML document for Intranet/Internet. FED8 is equipped with an interface to Excel for data exchange.

Spring Drawing

FED8 generates scale spring drawings in accordance with DIN 2091, which can be exported to CAD as DXF or IGES files.

Diagrams

Spring characteristic curves and spring operation are shown as a diagram on screen. The diagramms can be printed, or exported to CAD or text programs via DXF and IGES interfaces.

Quick Output

The Quick output allows the characteristic spring curve to be displayed on one screen along with the most important spring data.

Material Data Base

The characteristic data of the most important spring materials (tensile strength, perm. shearing stress in relation to bar diameter, shearing modulus, E-modulus, density) is taken by FED8 from the integrated data base. The DBF file can be edited and appended by the user.

Help System

You can display a help window for each input value. There are also auxiliary pictures for each symbol used, and each calculation formula. FED8 displays warnings when values are exceeded. For each error message you can display a more detailed description of the error and a remedy suggestion.

Hard and Software Requirements

FED8 is available as 32-bit and 64-bit application for Windows 10, Windows 7, Windows 8, Windows XP.

Scope of Delivery

The FED8 program (incl. sample data, auxiliary pictures, help texts), user manual, input forms, license for unlimited time use.
