Method and experimental facility for analyzing and controlling vibration characteristics of flexible joint and flexible armed lever

Abstract

An experimental facility for analyzing and controlling vibration characteristics of a flexible joint and a flexible armed lever comprises a sensor detecting unit (10), a data acquiring and processing unit (20) and an upper computer (30) which are sequentially connected to one another; and the sensor detecting unit (10) comprises a first coder (11), a second coder (12) and a first sensor (13). The method for analyzing and controlling the vibration characteristics of the flexible and the flexible armed lever comprises the following steps of respectively detecting position measurement signals of the flexible joint and bending and vibrating signals of the flexible armed lever by using the coders and the sensor; and performing calculation to respectively obtain vibration quantity data of the flexible joint and vibration quantity data of the flexible armed lever. Accurate data of joint vibration, armed lever vibration and tail end synthesized vibration caused by joint vibration and armed lever vibration can be obtained, the upper computer has an operation interface with a plurality of functions and is quite convenient to operate, and joint flexibility parameters can be recognized by the experimental facility through an experimental result and on the basis of theoretical analysis.
