Development of Instrumentation Adapted by C.M.M.S. Dedicate to Poly-articulated Mechanisms (Computer-assisted Maintenance Management System)

In this article three study phases have been discussed: Landing phase of a civil transport aircraft, when part of the flow entering the reactors is redirected by thrust reversers. Phase of the functional and technical study of which reflects on the aircraft maintenance component, without forgetting the phase of synthesis of the landing system mechanisms. The approach presented relates to the description of the different instruments and languages used for the control of vibratory behavior in a maintenance plan. Active devices are used mainly in systems where the excitation acts permanently on the system and the minimization of the amplitude of the vibrations is the dominant criterion. This is the reason why it is important to plan and control the technical aspect which will contain the landing system from the point of view of geometry, torques, positions, speeds and accelerations, and trajectories from the mechanism design phase.
