A low-profile shock isolating payload mounting assembly comprises a first mount, a second mount, and an isolator. The second mount is movable relative to the first mount and comprises a riser comprising an inclined surface. The isolator comprises an inner frame and an outer frame. The inner frame couples to the first mount and comprises a platform and a leg extending from the platform. The leg is inclined to be complementary to the inclined surface of the second mount. The outer frame couples to the second mount and comprises an opening for accessing the platform of the inner frame. The rail is inclined so as to be complementary to the leg to capture the leg between the rail of the outer frame and the inclined surface of the second mount. The isolator operates to dampen vibrations and shocks propagating between the first and second mounts.

Various embodiments provide a bush for isolating vibrations, the bush comprising: a first anchor part defining a longitudinal axis; a second anchor part disposed coaxially with respect to the first anchor part; a first resilient body operably engaged with the first anchor part; a second resilient body operably engaged with the second anchor part; and an inertial mass element disposed between the first anchor part and the second anchor part. The inertial mass element is independently connected to the first resilient body and the second resilient body. Also, the first resilient body, second resilient body and inertial mass element are arranged to isolate vibrations between the first anchor part and the second anchor part within a predetermined operational frequency range. Further, the inertial mass element is arranged to isolate the first anchor part and second anchor part from dynamic stiffness increases associated with eigenmodes of the first resilient body and the second resilient body in the predetermined operational frequency range.

Methods of attenuating vibration transfer to a body of a vehicle using a dynamic mass of the vehicle via minimizing a particular angular frequency of a wheel. One method includes receiving vehicle information over a time interval and determining, based on the vehicle information, an instantaneous angular velocity that corresponds to a particular angular frequency of the wheel. This method includes generating a gain-and-phase-compensated actuator drive command to counteract a vibration that occurs at the particular angular frequency of the wheel, which is based on the instantaneous angular velocity, and communicating the gain-and-phase-compensated actuator drive command to a hydraulic mount assembly that supports the dynamic mass. This method includes actuating an actuator of the hydraulic mount assembly in response to the gain-and-phase-compensated actuator drive command in order to minimize the vibration transfer to the body due to the vibration that occurs at the particular angular frequency of the wheel.
