    Abstract
  • In order to study the dynamic characteristics of metal helical spring and its dynamic stiffness response to driving frequency, a finite element model of the spring was set up by using FEM, its steady-state response was computed, its frequency-amplitude characteristic curve was analyzed, and an equivalent algorithm of its stiffness was proposed.Computation result shows that the dynamic stiffness of the spring increases with the increase of driving frequency in general tendency, it is minimal and smaller than the static stiffness of the spring corresponding to resonant frequency, however, it is maximal and greater than the static stiffness corresponding to anti-resonant frequency; the stiffness-frequency curves of finite element model and equivalent algorithm almost overlap, so the dynamic characteristic of the spring is remarkable, and the algorithm is feasible.
