Analysis of Satellite Coupled Dynamics Simulation Based On the Virtual Lab

摘要

Based on the Virtual. Lab software, this paper used multi-rigid body dynamics and soft multi-body dynamics theory as the foundation to establish the satellite coupled virtual prototype model including rotary table, rotating arm and the antenna. The simulation model is used to analyze the influence of the flexible rotary arm body on the satellite and obtain the rotating arm stress and deformation under the coupled conditions, which provides theory basis for the satellite design, the material selection of satellite rotary arm and other key component, and strength check under coupling dynamic load conditions. At the same time, this provides data support for the fatigue reliability research of future satellite key component.
