TRUSS ANTENNA REFLECTOR DEPLOYMENT DYNAMICS MODELLING METHOD BASED ON MULTI-BODY ANALYSIS TEST |
摘要 |
A truss antenna reflector deployment dynamics modelling method based on a multi-body analysis test, comprising: performing a reflector deployment test to obtain force, force moment and stress data of a key measuring point; constructing multi-body dynamics simulation software; optimizing the multi-body dynamics simulation software according to the comparison of a multi-body dynamics simulation analysis result of a force, a force moment and a stress of the key measuring point with a deployment test result; analyzing the reasonability of a satellite attitude change physical process according to a comparison result; constructing an equivalent mass unit, and performing calculation to obtain inertia time-varying and stress time-varying simplified dynamics models and a corresponding database which are required by satellite control system design, test and analysis simulation software; and comparing a three-axis attitude angle and a three-axis attitude angular velocity which are obtained through simulation analysis of the satellite control system design, test and analysis simulation software with a three-axis attitude angle and a three-axis attitude angular velocity which are obtained by the multi-body dynamics simulation software, and re-checking the simplified models and the database and judging whether engineering properties are met according to a comparison result. |
