Abstract:
This article presents a quasi–zero-stiffness isolator with a cam-based negative-stiffness mechanism, where the cam has a user-defined noncircular profile to generate negative stiffness to counterbalance the positive stiffness of the vertical spring and yield the quasi–zero-stiffness characteristic around the equilibrium position. Unlike previous studies, the proposed quasi–zero-stiffness isolator has the preferable feature that the desired cubic restoring force can be directly obtained through the well-designed profile of the cam in the negative-stiffness mechanism with the friction considered

Abstract:
In traditional quasi-zero-stiffness (QZS) isolation system, the negative stiffness part is usually fixed rigidly, lacking of effective amplifying mechanism. For reaching a quasi-zero state, the value of negative stiffness need to be very large to offset the positive stiffness of the structure. This paper proposes a novel isolator incorporating a flexible support to magnify negative stiffness part for effective realization of quasi-zero state. First, the concept and formulation of the innovative quasi-zero isolator are presented. Equivalent model for the flexibly supported negative stiffness pa

Abstract In order to solve the problem of low frequency vibration control more effectively, a new type of inertial actuator is proposed in this paper, which is different from the conventional type in that the linear stiffness is replaced by the quasi-zero stiffness. In this design, the structure mainly consisting of a horizontal spring and connecting rod provides negative stiffness to offset the positive stiffness of the vertical spring, which not only ensures sufficient static load capacity, but also reduces the dynamic stiffness of the mass near the equilibrium position.

Abstract:
Compared with the linear isolation system, the quasi-zero-stiffness (QZS) nonlinear isolation system has the characteristics of high static stiffness and low dynamic stiffness, which has better low-frequency vibration isolation performance. However, most of the existing QZS isolators only consider the quasi-zero-stiffness characteristic at the static equilibrium position achieved by the parallel connection of positive and negative stiffness structures. To optimize the isolation performance of the QZS system, a new isolation device based on the parallel connection of oblique springs and vertica

In this case, the demand for vibration isolation is more and more strict. Traditional passive vibration isolators consist of a linear spring and a viscous damper. Previous studies indicate that the performance of a traditional vibration isolator is enhanced as the stiffness of the associated spring approaches zero. The drawback of zero stiffness is that the system cannot sustain any disturbance. The quais-zero stiffness (QZS) system provides

Abstract:
Vibration is recognised as one of the most significant disturbances to the operation of mechanical systems. Many traditional vibration isolator designs suffer from the trade-off between load capacity and isolation performance. Furthermore, in providing sufficient stiffness in the vertical direction to meet payload weight requirements, isolators are generally overly stiff in the remaining five degrees of freedom (DOF). In order to address the limitations of traditional isolator designs, this thesis details the development of a 6-DOF active vibration isolation approach. The proposed solution is

Various quasi-zero stiffness (QZS) passive vibration isolators were developed for protecting a system against vibration. This paper presents active control of a QZS vibration isolator. First, a unified model of QZS passive vibration isolators with symmetric nonlinearity is presented, which is a Duffing equation with odd power polynomials. Based the unified model, vertical and horizontal actuations are proposed for active control of QZS isolators. Finally, active control scheme for a QZS vibration isolator are presented and the isolation performances are compared with simulations.
