Abstract

We present an analysis of the transfer function of a very low frequency folded pendulum resonator. It is shown that performance depends critically on centre of percussion tuning of the pendulum arms. Experimental measurements of the transfer function are shown to agree well with theory. The isolator achieves 90 dB isolation at 7 Hz.

    In that case, small changes in the payloads close to the buckling limit can significantly alter the response of the isolator [30]. Low frequency horizontal vibration isolators or horizontal QZS isolators can be realized with different means based on crossed-wire suspensions [1], Roberts linkages [11], folded pendulums [2,9] and inverted pendulums/elastic instability [10,30-32]. The current study focuses on designs which are on the verge of elastic instability.

    In the literature, there are various low-frequency vibration isolator designs [1–7]. These systems can be used to isolate instruments such as gravitational wave detectors, seismographs, laser Doppler vibrometers and atomic force microscopes from low frequency excitations [1–3]. They can also be used as pre-isolator systems for further stages of isolation processes [4–5].

    Citation Excerpt :

    An HSLDS isolator can be designed by paralleling the negative stiffness with the positive stiffness element. Many negative stiffness mechanisms have been studied in recent years, such as oblique springs [19–23], Euler buckled beams [24,25], cam-roller-spring mechanisms [26,27], inverted pendulums [28,29] and magnetic springs [30–33]. These mechanisms have been applied to passive nonlinear vibration isolators, with good performance for low-frequency vibration isolation.
