Check compression springs for safety against buckling. The required working deflection (given as the percentage ratio of the spring free length L 0 ) must be lower than the limit deflection determined for specified slenderness ratio L 0 /D given by the respective curve, as shown in the image.
For a spring that cannot be designed buckling-safe, use a pin or housing as a guide, or divide it into several short springs.
where:
- curve 1 - Parallel ground ends and guided mounting
- curve 2 - Without guided mounting or without parallel ground ends
