Compression Springs - Additional Calculation Dialog Box (AutoCAD Mechanical Toolset)

Buckling - Correction Value of Bearing

Is determined according to the spring bearing. The buckling safety is determined on the basis of the correction value of the bearing as well as other geometric characteristics.

Shear Force

The shear spring loading increases stress in the spring.

Shock Velocity

The shock spring loading influences the overall stress in the spring.

Wire Shot - Peened

For increasing of the spring strength, compression spring calculation takes into the consideration also Wire Shot - Peening. It is a kind of the spring wire surface treatment. After activation of this check box the spring fatigue life is selected according to the respective Goodman diagrams.
