| In this paper, two different type antennas are deeply researched,the tools are include MATLAB and ADAMS. The main work will be introduced as follows:1. Based on flexible multi-body analysis method,using the assumed mode method, objecting the characteristic of astromesh antenna,select a parallelogram truss element as the simplest physical moded of system and study on it.Based on lagrange mthod in multibody dynamic system,the flexible body dynamic equation of system has been built and the dynamic respond analysis results also has been.obtained.2. Based on the hoop truss deployable virtual prototype antenna which has been built by the former students,then building the model of simulation platform,including the long mast,short mast and satellite.Studying the dynamic response under three typical deployable types,getting the simulation results.and the results were compared,which to guild the engineering design.3. Using the tool of C++ Builder program language,combing the dynamic analysis software ADAMS and finite element analysis software ANSYS,using parametric modeling techniques.A large space deployable antenna dynamic analysis software were developed,using the software to simulate the dynamic model in detail,the results were obtained which were guilded the engineering design. |
