Study on static and dynamic characteristics of metal helical spring

摘要

In order to study the static and dynamic characteristics of metal helical spring, a finite element model of the spring was set up by using Ansys, An experiment was designed to validate the result, the results of the experiment and the Ansys proved that the static stiffness of metal helical spring is changed and remarkable dynamic characteristics existed in metal helical spring, 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 ant-i resonant frequency.
