Abstract
An isolating mount provides vibration isolation for a sensor that is sensitive to external vibration about a rotational axis thereof at low frequencies, and translational vibrations in all axes at high frequencies. The isolation mount comprises a frame surrounding the sensor, and includes a plurality of columnar or beam members which are flexible in shear and stiff in compression. The beam members have longitudinal axes which lie in a common plane, also defined by the X-Y axes of the sensor. Connector members to couple desired beam members between the frame and the sensor and other connector members couple other beam members from the frame to the main support structure. The beam members flex in both the X and Y axis and also the Z axis, which is perpendicular to the common plane, but because the beam members are very stiff in compression, the resistance to any rotational movement about the Z axis is high. The columnar members are made up of a plurality of generally parallel metal shims which are molded together with a suitable elastomeric material and wherein the shims are spaced to obtain the desired flexing in shear and stiffness in compression for the mounting.
