摘要：

How to achieve the resonance and dynamic stress so as to reduce the residual stress of high stiffness workpieces remains a hot potato because during use the exciting frequency of traditional VSR devices is far lower than the lower order natural frequency of the high stiffness workpiece. A novel VSR device with nonlinear superharmonic vibration and its mathematical model are proposed in this paper. The mechanisms to reduce the residual stress of this device is studied from the points of exciting frequency and exciting force. Then the condition of the device system to happen the superharmonic vibration is obtained. The parametric relations of the system elements are gained from the relation of dynamic stress and the response amplitude of the superharmonic vibration.
