Finding Spring Constant in horizontal direction

Click For Summary
SUMMARY

The discussion focuses on calculating the spring constant K' for a helical spring when subjected to transverse loads, particularly in a Shale Shaker application. The standard formula for spring constant, K = Applied Force/Resulting Deflection, applies, but the suitability of helical springs for transverse loading is questioned due to potential nonlinearity and risk of damage. The conversation emphasizes the need for direct measurements to accurately determine K' in this orientation, especially given the 45-degree vibration direction.

PREREQUISITES
  • Understanding of spring mechanics and constants
  • Familiarity with helical spring design and applications
  • Knowledge of vibration analysis in mechanical systems
  • Experience with experimental measurement techniques
NEXT STEPS
  • Research methods for measuring transverse spring constants in helical springs
  • Study the effects of nonlinearity in spring behavior under transverse loads
  • Explore literature on spring applications in Shale Shakers
  • Investigate alternative spring designs suitable for transverse loading
USEFUL FOR

Mechanical engineers, vibration analysts, and anyone involved in the design and application of springs in machinery, particularly in contexts involving transverse loads and dynamic systems.

Hello All,
Again, a funny question is raised:

From the following site, I can determine the spring constant K for a compression spring at vertical axis.

However, I wonder is there any equation to find the spring constant k' at horizontal position, as shown in following picture:

Thanks for your kind help!

Hi there Su :smile: I might be mistaken, but I would presume that a helical spring is not intended to bear a load in the transverse direction as you have pictured. It would probably at best show nonlinearity at large deflections and at worst damage the spring. That being said, if you still want to calculate some sort of 'transverse spring constant' it would be defined the same way.

K = Applied Force/Resulting Deflection

I am not sure what the best way to model this would be though. Taking direct measurements would probably be best but I am not sure.

Thanks for your Reply.
The spring is used in a Shale Shaker.
Since the vibration direction is 45deg to the ground level, I am curious about the spring constant K' in transverse direction.
I am wonder whether there is any literature about it.

P.s. Small amplitude only compares to the Spring Length
