AbstractDynamic analysis of flexible multibody systems is complex. Several successful methods have been demonstrated. However, few works discussed the dynamic performance of the flexible multibody under different temperatures. This paper uses the absolute nodal coordinate formulation to analyze the flexible body dynamics of deployment structures under different temperatures to simulate space environments. The dynamic equations of finite element in temperature field are developed. Then a computer-aided simulation of flexible multibody systems in temperature field is implemented. A general four-bar mechanism under different temperatures as a simulation example is demonstrated, and the deployment characteristics of a special four-bar mechanism as a basic module of the hoop truss deployable antenna is analyzed under different temperatures in order to evaluate the dynamic performance of the deployable antenna in space environments. The simulation results indicate the influence factors of deployment dynamic characteristics include the structural form, material properties, geometric parameters and deployment planning in ambient and thermal/vacuum environments.
