Load in Lbs at a Given Deflection and Flat Theoretic Formulas

Disc Spring Load Calculations Index

• Nomenclature used in spring calculations
• Load in Lbs at a Given Deflection and Flat theoretic formulas
• True Radius Factor Shape of the actual edge has an impact.
• Corner Radius Factor A spring does not have square corners
• True Cone Height Factor The flat area at the middle of the spring
• Flattening at Edge Factor The flat area at the edge of the spring
• Precise Load Computing Program​​

Note: The load-deflection formulas were developed by J. Almen and A. Laszio, and published in the Transactions of American Society of Mechanical Engineers, May 1936, and is shown in the figure above.
