Research on the Vibration Analysis of Cantilever Truss Structure and its Test

Abstract:

Based on the background of rotary platform of launching tower ,the continuum method based on rigidity equivalent principle and mass equivalent principle is used to transform the truss structure to an uniform solid cantilever beam rotating around its edge ,which makes the vibration equations establishment with methods of parameter supposition and numerical analysis possible . The agreement of the calculation results and the test results means method of this paper available in the vibration analysis of cantilever truss structure .
