摘　　要：太阳帆可以通过气体驱动支撑管而展开。针对太阳帆充气展开方式,分别对"Z"型8折管整体与分段充气模型建立有中心刚体与无中心刚体约束两种情况的有限元模型;针对分段充气模型,根据充气装置的位置分别建立自由端与固支端充气模型。应用动力学显式求解软件LS-DYNA进行太阳帆支撑管充气展开仿真模拟,并对仿真结果进行了分析。Solar sail can be deployed by gas injected into its support booms.For inflatable deployment mode of solar sail,integral and segmental inflation finite element models of Z-type 8 folded tubes with and without central rigid body restraint are set up respectively in the paper;For the segmental inflation model,both free and fixed end inflation models are separately built according to the location of the inflation device.The dynamics explicit solver software,LS-DYNA,is adopted to simulate the deployment dymamics of solar sail support booms and simulation results are analyzes.
