How to Calculate the Fatigue Limit of Leaf Springs?

AI Thread Summary
To calculate the fatigue limit of leaf springs, one must use stress equations specific to leaf springs to determine the stress values. These stress values can then be applied to the S-N curve relevant to the material being used. There is no shortcut; a thorough understanding of material properties and stress analysis is essential. The process involves correlating cycles to failure with the derived stress values. Accurate calculations are crucial for ensuring the durability and performance of leaf springs.

Hi to all.

How would I go about calculating the fatigue limit of leaf springs?

Is there an equation out there in the form of

N, cycles to failure= f(variables, material properties)


Or will I have to use the Stress equations for leaf springs and use that stress value and
then look up a S-N curve for that particular material??


Tnx in advance.

There are no shortcuts in this life. You will have to use the stress equations for the springs and then use those stresses in the S-N curve for the material. That's what you'll be getting the big bucks to do!

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
