Abstract A chaotic vibration isolation device under the condition of small displacement is designed according to the chaotic vibration theory.The device can generate strong nonlinearity under small displacement. The linear part and the nonlinear part are completely separated. The overall stiffness, the ratio of linear term to nonlinear term can be easily adjusted. The engineering application scope of the device turns wider. The numerical simulation is carried out with specific parameters. The design is confirmed.
