END CONDITION CONSTANTS FOR SPRING STABILTY ANALYSIS |
|
End Condition |
Constant (α) |
|
Spring supported between flat parallel surfaces (fixed ends) |
0.5 |
|
One end supported by flat surface perpendicular to spring axis (fixed);
other end pivoted (hinged) |
0.707 |
|
Both ends pivoted (hinged) |
1 |
|
One end clamped; other end free |
2 |
Note: Ends supported by flat surfaces must be squared and ground.
