Passive vibration isolator with profiled supports

摘要

A passive vibration isolator that contains a resilient element supported by a first support and a second support. The resilient element reacts with one or more of the supports so that the isolator has a natural frequency versus load curve. The curve has a first portion with a varying natural frequency and a second portion with a relatively constant frequency. The second support may have a profile so that a contact area of the support is approximately constant in the first portion of the curve and varies in the second portion of the curve.
