Definitions

  • an assembly for adaptively controlling vibration, shock, acceleration and position of an item mounted to the assembly independent of the varying operating characteristics of the item or a support platform for the assembly.
  • the assembly comprises a vibrating item to be controlled, a support platform for supporting the item, a viscous spring damper mechanically intercoupled between the item and the platform, first sensing means for sensing vibration, shock, acceleration and position of the item, second sensing means for sensing vibration, shock, acceleration and position of the support platform, a gas supply source for selectively supplying gas to the viscous spring damper, a fluid supply source for selectively supplying fluid to the viscous spring damper, and, logic control means operatively engaged to the first and the second sensing means, the gas supply source and the fluid supply source for comparing vibration, shock, acceleration and position of the item and the support platform.
  • the logic control means adjusts the inputs from the gas supply source and the fluid supply source to selectively adjust the operation of the viscous spring damper and the dynamic mechanical coupling of the
  • the logic control means compares an output of the first sensing means and the second sensing means with preselected reference values for selectively operating the servovalve in response to the output of the sensing means.
  • Elastomeric shear spring 26 supports a portion of the item or load being carried by the damper 20 and additionally serves as a seal for main fluid chamber 34 between the inner and outer members 22, 24.
  • the use of the elastomeric shear spring 26 as a seal between the inner and outer members has the advantage over most damping units in that no sliding surfaces are involved. Thus, the durability of the seal is greatly increased in comparison with most commercial units. Additionally, by using an elastomeric shear spring 26, the device can take a degree of conical and torsional misalignment which cannot be tolerated in many other types of damping devices.
