A CAD Program for the automated checkout and design of Belleville springs

A CAD method for the checkout and design of Belleville springs is presented. The method eliminates the need to resort to conventional trial-and-error techniques. In a matter of seconds, it rapidly and accurately checks out and designs Belleville springs, outputting the load-deflection characteristics in graphic and table formats and can generate a dimensioned drawing. To enable the designer to work in the same environment, the software has been provided with a user-friendly interface for fatigue calculation along with the characteristics of parallel/series assemblies. The algorithms developed and used for each calculation module are illustrated.
