Article Preview

A helical spring has large deformation under the condition of near resonance, in order to obtain the nonlinear vibration characteristics, the single-integral constitutive relations of helical spring based on nonlinear theory are discussed firstly, then nonlinear dynamic characteristics of helical spring are analyzed based on finite element technology. Finally, the dynamic simulation associated with flexible characteristics for helical spring is studied in ADAMS. The results show that the maximum stress of helical spring appears at transition region between different radius which is consistent with fracture position actually. Flexible dynamic response of helical spring mainly behaves low frequency vibration which is different from rigid body dynamics response.
