✦ Synopsis

The compensation of wbraUons generated by the rotor of a helicopter and transmitted to the cabin is of great importance for rotorcraft design These vlbraUons occur at discrete, well known frequencies, the so-called rotor-blade harmomc frequencies In this paper the apphcatlon of actwe control technology is investigated for wbratlon compensation The multwarlable model of the hehcopter ~s first decoupled m three subsystems Then, a compensator xs developed, which xsolates the cabin from the oscdlatmg rotor/gear-box umt at the first harmomc frequency and at the same t~me fixes the cabin to the rotor/gear-box unit for ascend or descend maneuvers

## A procedure is developed which uses bond graph modeling and a digital computer to determine if semi-active control can provide a suitable performance in an application where totally active control is considered. The application areas principally addressed are those in which the disturbance inpu

A helicopter gearbox support strut has been set up in the laboratory under realistic loading conditions to investigate the active control of longitudinal and lateral vibration transmission to a connected receiving structure. Three magnetostrictive actuators were clamped to the strut to introduce sec

This paper compares the force feedback and acceleration feedback implementation of the sky-hook damper when it is used to isolate a flexible structure from a disturbance source. It is shown that the use of a force sensor produces always alternating poles and zeros in the open-loop transfer function
