Suspended low-frequency horizontal pendulum isolator for vibration isolation systems

摘要

A horizontal frequency vibration pendulum isolator which comprises a pendulum which has an upper end flexibly secured to a vertical isolator. The pendulum is received within a hollow leg and is supported at its lower end by pendulum wires which wires are secured to the hollow leg which is grounded. The wires are specifically angled with reference to the longitudinal axis of the pendulum to impart to the horizontal isolator a known or designed horizontal stiffness.
