A mathematical equation system was developed to calculate the natural frequencies of helical springs, and its predictions were compared with finite element simulation. The general equations governing the vibration of helical springs were derived, describing the characteristics of the spring oscillation.
A system of mathematical equations was developed for the calculation of the natural frequencies of helical springs, its predictions being compared with finite element simulation with ANSYS (R). Authors derive the general equations governing the helical spring vibration relative to the Frenet trihedral representing the normal, binormal and tangent unit vectors to the spring medium line. The dispersion relation omega = f (k) has been obtained to model a wave traveling along the axis of the wire.
