Today, we are going to discuss the "Allowable bending stress graph for springsHere is a note about "The
Compression spring calculation,In order to determine the maximum stress at which a spring can be used without breaking, it is necessary to know the stress rate.Its stress rate is(Torsional Modified Stress / Allowable Bending Stress)*100 Using the calculation of theStresses that can be used if the calculation result is less than 80 It is good to be aware that this is the case.
As for the flow.
- Find the torsional stress (τo) generated when P (load) is applied to a coil spring of effective diameter D and strand diameter d.
- Since the actual spring has different stresses on the inside and outside of the coil, the torsional stress (torsional modified stress) is recalculated using the Wahl modification factor (K) to account for this effect. (K*τo)
- Confirm that the torsional modification stress is less than 80% of the allowable bending stress presented here.
This is the school of
I will note the allowable bending stress graph of the spring that is used for this purpose, albeit briefly.

That's it.
