On the Stress Distribution in Slotted Cylinder Springs

SUMMARY

A critical analysis of the scientific literature shows that, contrary to helical and other springs widely used in practice, slotted cylinder springs have been insufficiently documented to date. Currently, given the under exploited potential of their particular mechanical properties, a further investigation is much necessary in order to extend their use to as many as possible areas of technology. This is quite possible thanks to the most recent state of mechanical design research and technology. This paper is a part of a project that aims at developing specific computer software tools allowing precise analytic stress state determination. It develops a statically indeterminate approach of the problem of the stress behaviour of such springs, following which previously and three newly proposed models are compared one with another on the basis of ratios between Von Mises’ stresses. Finally, for the case of two slots per section slotted cylinder springs, it is concluded that the analytical solution of the two degrees of freedom proposed primary system is in good agreement with empirical and Computer Aid Design res-olutions. A generalization to higher number of slots per section springs is foreseen using the same methodology.
