摘要：

Nonlinear Quasi-zero stiffness (QZS) mechanisms were studied to overcome the weakness of linear isolators. This paper presents an integrated design of the QZS mechanism. First, various types of QZS vibration mechanisms are analyzed and a generalized model for QZS mechanisms is derived. The generalized model consists of two main parts: link and horizontal spring. The motion equation of the QZS mechanism is a Duffing equation with nonlinear stiffness. Based on the generalized model, the design problem of the QZS mechanism is converted into the kinematic design of a link element. For simplicity, the link is generalized with a cam-roller mechanism. The integrated design approach shows that the QZS mechanism can have desired QZS characteristics with properly designed cam geometry.
